Applies to:
Oracle Server - Enterprise Edition - Version: 8.1.7.4 to 10.2.0.5 - Release: 8.1.7 to 10.2
Oracle Server - Standard Edition - Version: 8.1.7.4 to 10.2.0.5   [Release: 8.1.7 to 10.2]
Information in this document applies to any platform.

Purpose
This document is created for use as a guideline and checklist when manually upgrading Oracle 8i, Oracle 9i or Oracle 10gR1 to Oracle 10gR2 on a single server.

If the database instance is being moved from one server to another as part of the upgrade process, additional steps for that move may need to be performed which are not included in this checklist.

This document is divided into three major sections.
-- Preparing to Upgrade
-- Upgrading to the New Oracle Database 10g Release 2
-- After Upgrading a Database

Please read the whole article before starting to perform an upgrade

Additional Note:

These instructions are incomplete for taking an 8i OPS cluster into a 10gR2 RAC cluster due to the differences in OPS vs RAC.

Please also note that Oracle have made an "Oracle10g Upgrade Companion" available. For further information, please review:

Note:466181.1 "10g Upgrade Companion"

The above document is continually updated as new information becomes available.

Compatibility Matrix

Minimum Version of the database that can be directly upgraded to Oracle 10g Release 2
8.1.7.4 -> 10.2.X.X.X
9.0.1.4 or 9.0.1.5 -> 10.2.X.X.X
9.2.0.4 or higher -> 10.2.X.X.X
10.1.0.2 or higher -> 10.2.X.X.X

The following database version will require an indirect upgrade path.

7.3.3 (or lower) -> 7.3.4 -> 8.1.7 -> 8.1.7.4 -> 10.2.X.X.X
7.3.4 -> 8.1.7 -> 8.1.7.4 -> 10.2.X.X.X
8.0.n -> 8.1.7 -> 8.1.7.4 -> 10.2.X.X.X
8.1.n -> 8.1.7 -> 8.1.7.4 -> 10.2.X.X.X

Steps for Upgrading the Database to 10g Release 2
Preparing to Upgrade
In this section all the steps need to be performed to the previous version of Oracle.  Please note that the database must be running in normal mode in the old release.

Step 1:

Log in to the system as the owner of the new 10gR2 ORACLE_HOME and copy the following files from the 10gR2 ORACLE_HOME/rdbms/admin directory to a directory outside of the Oracle home, such as the /tmp directory on your system:

ORACLE_HOME/rdbms/admin/utlu102i.sql
ORACLE_HOME/rdbms/admin/utltzuv2.sql

Make a note of the new location of these files.

Step 2:

Change to the temporary directory that you copied files to in Step 1.

Start SQL*Plus and connect to the database instance you are intending to upgrade (running from the original ORACLE_HOME) as a user with SYSDBA privileges. Then run and spool the utlu102i.sql file. sqlplus '/as sysdba'

SQL> spool Database_Info.log
SQL> @utlu102i.sql
SQL> spool off
Please note:  The instance can be running in normal mode and does not need to be running in a restricted (migrate / upgrade) mode to run the script. Also, the instance must not be running in read-only mode.  A few registry$ tables may be created, if they do not already exist, and some rows may be inserted into existing Upgrade tables.

Then, check the spool file and examine the output of the upgrade information  tool. The sections which follow, describe the output of the Upgrade Information Tool (utlu102i.sql).

NOTE: If you are upgrading from 8.1.7.4, the utlu102i.sql script will fail with an ORA-1403 error. Please follow the workaround in Note:5640527.8 (or Note:407031.1) to enable utlu102i.sql to run.

Database:

This section displays global database information about the current database such  as the database name, release number, and compatibility level. A warning is displayed if the COMPATIBLE initialization parameter needs to be adjusted before the database is  upgraded.

Logfiles:

This section displays a list of redo log files in the current database whose size is  less than 4 MB. For each log file, the file name, group number, and recommended size  is displayed. New files of at least 4 MB (preferably 10 MB) need to be created in the current database. Any redo log files less than 4 MB must be dropped before the database is upgraded.

Tablespaces:

This section displays a list of tablespaces in the current database. For each tablespace, the tablespace name and minimum required size is displayed. In addition, a message is  displayed if the tablespace is adequate for the upgrade. If the tablespace does not have enough free space, then space must be added to the tablespace in the current database. Tablespace adjustments need to be made before the database is upgraded.

Update Parameters:

This section displays a list of initialization parameters in the parameter file of the  current database that must be adjusted before the database is upgraded. The adjustments need to be made to the parameter file after it is copied to the new Oracle Database 10g release.

Deprecated Parameters:

This section displays a list of initialization parameters in the parameter file of the  current database that are deprecated in the new Oracle Database 10g release.

Obsolete Parameters:

This section displays a list of initialization parameters in the parameter file of the  current database that are obsolete in the new Oracle Database 10g release. Obsolete initialization parameters need to be removed from the parameter file before the database is upgraded.

Components:

This section displays a list of database components in the new Oracle Database 10g release that will be upgraded or installed when the current database is upgraded.

Miscellaneous Warnings:

This section provides warnings about specific situations that may require attention before and/or after the upgrade.

SYSAUX Tablespace:

This section displays the minimum required size for the SYSAUX tablespace, which is required in Oracle Database 10g. The SYSAUX tablespace must be created after the new Oracle Database 10g release is started and BEFORE the upgrade scripts are invoked.

Step 3:

Check for the deprecated CONNECT Role

After upgrading to 10gR2, the CONNECT role will only have the CREATE SESSION privilege; the other privileges granted to the CONNECT role in earlier releases will be revoked during the upgrade. To identify which users and roles in your database are granted the CONNECT role, use the following query:

 

SELECT grantee FROM dba_role_privs
WHERE granted_role = 'CONNECT' and
grantee NOT IN (
'SYS', 'OUTLN', 'SYSTEM', 'CTXSYS', 'DBSNMP',
'LOGSTDBY_ADMINISTRATOR', 'ORDSYS',
'ORDPLUGINS', 'OEM_MONITOR', 'WKSYS', 'WKPROXY',
'WK_TEST', 'WKUSER', 'MDSYS', 'LBACSYS', 'DMSYS',
'WMSYS', 'OLAPDBA', 'OLAPSVR', 'OLAP_USER',
'OLAPSYS', 'EXFSYS', 'SYSMAN', 'MDDATA',
'SI_INFORMTN_SCHEMA', 'XDB', 'ODM');
If users or roles require privileges other than CREATE SESSION, then grant  the specific required privileges prior to upgrading. The upgrade scripts  adjust the privileges for the Oracle-supplied users.

In Oracle 9.2.x and 10.1.x CONNECT role includes the following privileges:

SELECT GRANTEE,PRIVILEGE FROM DBA_SYS_PRIVS
WHERE GRANTEE='CONNECT'

GRANTEE PRIVILEGE
------------------------------ ---------------------------
CONNECT CREATE VIEW
CONNECT CREATE TABLE
CONNECT ALTER SESSION
CONNECT CREATE CLUSTER
CONNECT CREATE SESSION
CONNECT CREATE SYNONYM
CONNECT CREATE SEQUENCE
CONNECT CREATE DATABASE LINK

In Oracle 10.2 the CONNECT role only includes CREATE SESSION privilege.

Step 4:

Create the script for dblink incase of downgrade of the database.

During the upgrade to 10gR2, any passwords in database links will be encrypted.  To downgrade back to the original release, all of the database links with encrypted passwords  must be dropped prior to the downgrade. Consequently, the database links will not exist in the downgraded database. If you anticipate a requirement to be able to downgrade back to your  original release, then save the information about affected database links from the SYS.LINK$ table,  so that you can recreate the database links after the downgrade.

Following script can be used to construct the dblink.

SELECT
'create '||DECODE(U.NAME,'PUBLIC','public ')||'database link '||CHR(10)
||DECODE(U.NAME,'PUBLIC',Null, U.NAME||'.')|| L.NAME||chr(10)
||'connect to ' || L.USERID || ' identified by '''
||L.PASSWORD||''' using ''' || L.host || ''''
||chr(10)||';' TEXT
FROM sys.link$ L,
sys.user$ U
WHERE L.OWNER# = U.USER# ;
Step 5:

Check for the TIMESTAMP WITH TIMEZONE Datatype. Please this step is only required for the 10gR1 The may affect existing data of TIMESTAMP WITH TIME ZONE datatype.
For example, if users enter TIMESTAMP '2003-02-17 09:00:00 America/Sao_Paulo', we convert the data to UTC based on the transition rules in the time zone file and store them on the disk. So '2003-02-17 11:00:00' along with the time zone id  for 'America/Sao_Paulo' is stored because the offset for this particular time is '-02:00'. Now the transition rules are modified and the offset for this particular time is changed to '-03:00'. when users retrieve the data, they will get  '2003-02-17 08:00:00 America/Sao_Paulo'. There is one hour difference compared to the  original value.

Change to the temporary directory that you copied files to in Step 1.

Start SQL*Plus and connect to the database instance as a user with SYSDBA privileges. Then run and spool the utltzuv2.sql file.

$ sqlplus '/as sysdba'

SQL> spool TimeZone_Info.log
SQL> @utltzuv2.sql
SQL> spool off

If the utltzuv2.sql script identifies columns with time zone data affected by a database upgrade, then use the solution to solve this problem.

create tables with the time zone information in character format  (for example, TO_CHAR(column, 'YYYY-MM-DD HH24.MI.SSXFF TZR'), and recreate  the TIMESTAMP data from these tables after the upgrade.

For example, user scott has a table tztab:
create table tztab(x number primary key, y timestamp with time zone);
insert into tztab values(1, timestamp '');

Before upgrade, you can create a table tztab_back, note column y here is defined as VARCHAR2 to preserve the original value.

create table tztab_back(x number primary key, y varchar2(256));
insert into tztab_back select x,
to_char(y, 'YYYY-MM-DD HH24.MI.SSXFF TZR') from tztab;

After upgrade, you need update the data in the table tztab using the value in tztab_back.
update tztab t set t.y = (select to_timestamp_tz(t1.y,
'YYYY-MM-DD HH24.MI.SSXFF TZR') from tztab_back t1 where t.x=t1.x);

Step 6:

Starting in Oracle 9i the National Characterset (NLS_NCHAR_CHARACTERSET) will be limited to UTF8 and AL16UTF16. Any other NLS_NCHAR_CHARACTERSET will no longer be supported.

For more details, refer to Note:276914.1 "The National Character Set in Oracle 9i and 10g"

NOTE: If you are upgrading from Oracle9i to 10g, skip to step 7.

When upgrading from Oracle8i to 10g the value of NLS_NCHAR_CHARACTERSET is based on value currently used in the Oracle8i version.

If the NLS_NCHAR_CHARACTERSET is UTF8 then new it will stay UTF8. In all other cases the NLS_NCHAR_CHARACTERSET is changed to AL16UTF16 and -if used- N-type data (= data in columns using NCHAR, NVARCHAR2 or NCLOB ) may need to be converted.

The change itself is done in step 38 by running the upgrade script.

To check whether there are any N-type objects in a database, run the following query:

    select distinct OWNER, TABLE_NAME
    from DBA_TAB_COLUMNS
    where DATA_TYPE in ('NCHAR','NVARCHAR2', 'NCLOB')
    and OWNER not in ('SYS','SYSTEM','XDB');

If no rows are returned it should mean that the database is not using N-type columns for user data, so simply go to the next step.

If you have N-type columns for user data then run the following query:

SQL> select * from nls_database_parameters where parameter ='NLS_NCHAR_CHARACTERSET';

If you are using N-type columns AND your National Characterset is UTF8 or is in the following list:

JA16SJISFIXED , JA16EUCFIXED , JA16DBCSFIXED , ZHT32TRISFIXED
KO16KSC5601FIXED , KO16DBCSFIXED , US16TSTFIXED , ZHS16CGB231280FIXED
ZHS16GBKFIXED , ZHS16DBCSFIXED , ZHT16DBCSFIXED , ZHT16BIG5FIXED
ZHT32EUCFIXED

then also simply go to point next step. The conversion of the user data itself will then be done in step 38

If you are using N-type columns AND your National Characterset is NOT UTF8 or NOT in the following list:

JA16SJISFIXED , JA16EUCFIXED , JA16DBCSFIXED , ZHT32TRISFIXED
KO16KSC5601FIXED , KO16DBCSFIXED , US16TSTFIXED , ZHS16CGB231280FIXED
ZHS16GBKFIXED , ZHS16DBCSFIXED , ZHT16DBCSFIXED , ZHT16BIG5FIXED
ZHT32EUCFIXED

(your current NLS_NCHAR_CHARACTERSET is for example US7ASCII, WE8ISO8859P1, CL8MSWIN1251 ...)

then you have to:

change the tables to use CHAR, VARCHAR2 or CLOB instead the N-type
or
use export/import the table(s) containing N-type column and truncate those tables before migrating to 10g
The recommended NLS_LANG during export is simply the NLS_CHARACTERSET, not the NLS_NCHAR_CHARACTERSET

Step 7:

When upgrading to Oracle Database 10g, optimizer statistics are collected  for dictionary tables that lack statistics. This statistics collection can be time consuming for databases with a large number of dictionary tables,  but statistics gathering only occurs for those tables that lack statistics  or are significantly changed during the upgrade.

To decrease the amount of downtime incurred when collecting statistics, you can collect statistics prior to performing the actual database upgrade.

As of Oracle Database 10g Release 10.1, Oracle recommends that you use the DBMS_STATS.GATHER_DICTIONARY_STATS procedure to gather these statistics. You can enter the following:

$ sqlplus '/as sysdba'

SQL> EXEC DBMS_STATS.GATHER_DICTIONARY_STATS;

For Oracle8i and Oracle9i, use the DBMS_STATS.GATHER_SCHEMA_STATS procedure to gather statistics.

Current Statistics if desired, can be backed up prior to gathering current statistics and is useful if you want to revert back the statistics post upgrade.
Process to backup the existing statistics as follows:

$ sqlplus '/as sysdba'
SQL>spool sdict

SQL>grant analyze any to sys;

SQL>exec dbms_stats.create_stat_table('SYS','dictstattab');

SQL>exec dbms_stats.export_schema_stats('WMSYS','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('MDSYS','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('CTXSYS','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('XDB','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('WKSYS','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('LBACSYS','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('OLAPSYS','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('DMSYS','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('ODM','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('ORDSYS','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('ORDPLUGINS','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('SI_INFORMTN_SCHEMA','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('OUTLN','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('DBSNMP','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('SYSTEM','dictstattab',statown => 'SYS');
SQL>exec dbms_stats.export_schema_stats('SYS','dictstattab',statown => 'SYS');

SQL>spool off
This data is useful if you want to revert back the statistics
For example, the following PL/SQL subprograms import the statistics for the SYS schema after deleting the existing statistics:

exec dbms_stats.delete_schema_stats('SYS');
exec dbms_stats.import_schema_stats('SYS','dictstattab');

To gather statistics run this script, connect to the database AS SYSDBA using SQL*Plus.

$ sqlplus '/as sysdba'

SQL>spool gdict

SQL>grant analyze any to sys;

SQL>exec dbms_stats.gather_schema_stats('WMSYS',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('MDSYS',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('CTXSYS',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('XDB',options=>'GATHER',

SQL>exec dbms_stats.gather_schema_stats('WKSYS',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('LBACSYS',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('OLAPSYS',options=>'GATHER',

method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('ODM',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('ORDSYS',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('ORDPLUGINS',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('SI_INFORMTN_SCHEMA',options=>'GATHER',

method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('OUTLN',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('DBSNMP',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('SYSTEM',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
SQL>exec dbms_stats.gather_schema_stats('SYS',options=>'GATHER',
estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);

SQL>spool off

Step 8:

Check for invalid objects in the database:

spool invalid_pre.lst
select substr(owner,1,12) owner,
substr(object_name,1,30) object,
substr(object_type,1,30) type, status from
dba_objects where status <> 'VALID';
spool off

Run the following script as a user with SYSDBA privs using SQL*Plus and then requery invalid objects:

% sqlplus '/as sysdba'
SQL> @?/rdbms/admin/utlrp.sql

This last query will return a list of all objects that cannot be recompiled before the upgrade in the file 'invalid_pre.lst'

If you are upgrading from Oracle9iR2 (9.2), verify that the view dba_registry contains data. If the view is empty, run the following scripts from the 9.2 home:

% sqlplus '/as sysdba'
SQL> @?/rdbms/admin/catalog.sql
SQL> @?/rdbms/admin/catproc.sql
SQL> @?/rdbms/admin/utlrp.sql

and verify that the dba_registry view now contains data.

Step 9:

Check for corruption in the dictionary, use the following commands in sqlplus connected as sys:

 

Set verify off
Set space 0
Set line 120
Set heading off
Set feedback off
Set pages 1000
Spool analyze.sql

Select 'Analyze cluster "'||cluster_name||'" validate structure cascade;'
from dba_clusters
where owner='SYS'
union
Select 'Analyze table "'||table_name||'" validate structure cascade;'
from dba_tables
where owner='SYS' and partitioned='NO' and (iot_type='IOT' or iot_type is NULL)
union
Select 'Analyze table "'||table_name||'" validate structure cascade into invalid_rows;'
from dba_tables
where owner='SYS' and partitioned='YES';

spool off

This creates a script called analyze.sql.
Now execute the following steps.

$ sqlplus '/as sysdba'
SQL> @$ORACLE_HOME/rdbms/admin/utlvalid.sql
SQL> @analyze.sql

This script (analyze.sql) should not return any errors.

Step 10:

Ensure that all Materialized views / Snapshot refreshes are successfully completed, and that replication must be stopped (ie: quiesced).

$ sqlplus '/ as sysdba'
SQL> select distinct(trunc(last_refresh)) from dba_snapshot_refresh_times;

You can also use:

SQL> select distinct owner, name mview, master_owner master_owner, last_refresh from dba_mview_refresh_times;

Step 11:

Stop the listener for the database:

$ lsnrctl
LSNRCTL> stop

Ensure no files need media recovery:

$ sqlplus '/ as sysdba'
SQL> select * from v$recover_file;

This should return no rows.

Step 12:

Ensure no files are in backup mode:

SQL> select * from v$backup where status!='NOT ACTIVE';

This should return no rows.

Step 13:

Resolve any outstanding unresolved distributed transaction:

SQL> select * from dba_2pc_pending;

If this returns rows you should do the following:

SQL> select local_tran_id from dba_2pc_pending;
SQL> execute dbms_transaction.purge_lost_db_entry('');
SQL> commit;

Step 14:

Disable all batch and cron jobs.

Step 15:

Ensure the users sys and system have 'system' as their default tablespace.

SQL> select username, default_tablespace from dba_users
where username in ('SYS','SYSTEM');

To modify use:

SQL> alter user sys default tablespace SYSTEM;
SQL> alter user system default tablespace SYSTEM;

Step 16:

Ensure that the aud$ is in the system tablespace when auditing is enabled.

SQL> select tablespace_name from dba_tables where table_name='AUD$';

If the AUD$ table exists, and is in use, upgrade performance can be effected depending on the number of records in the table. 

Please refer to the following note for information on exporting and truncating the AUD$ table:

Note.979942.1 Ext/Pub Database upgrade appears to have halted at SYS.AUD$ Table

 

Step 17:

Note down where all control files are located.

SQL> select * from v$controlfile;

Step 18:

If table XDB.MIGR9202STATUS exists in the database, drop it before upgrading the database (to avoid the issue described in Note:356082.1)

Step 19:

Shutdown the database

$ sqlplus '/as sysdba'
SQL> shutdown immediate;

Step 20:

Perform a full cold backup (or an online backup using RMAN)

You can either do this by manually copying the files or sign on to RMAN:

$ rman "target / nocatalog"

And issue the following RMAN commands:

RUN

}

Upgrading to the New Oracle Database 10g Release 2
Step 21:

Update the init.ora file:

- Make a backup of the old init.ora file

- Copy it from the old (pre-10.2) ORACLE_HOME to the new (10.2) ORACLE_HOME

    On Unix/Linux, the default location of the file is the $ORACLE_HOME/dbs directory

- Comment out any obsoleted parameters (listed in appendix A).

- Change all deprecated parameters (listed in appendix B).

- Set the COMPATIBLE initialization parameter to an appropriate value. If you are
upgrading from 8.1.7.4 then set the COMPATIBLE parameter to 9.2.0 until after the
upgrade has been completed successfully. If you are upgrading from 9.2.0 or 10.1.0
then leave the COMPATIBLE parameter set to it's current value until the upgrade
has been completed successfully. This will avoid any unnecessary ORA-942 errors
from being reported in SMON trace files during the upgrade (because the upgrade
is looking for 10.2 objects that have not yet been created)

- If you have the parameter NLS_LENGTH_SEMANTICS currently set to CHAR, change the value
to BYTE during the upgrade (to avoid the issue described in Note:4638550.8)

- Verify that the parameter DB_DOMAIN is set properly.

- Make sure the PGA_AGGREGATE_TARGET initialization parameter is set to
at least 24 MB.

- Ensure that the SHARED_POOL_SIZE and the LARGE_POOL_SIZE are at least 150Mb.
Please also the check the "KNOWN ISSUES" section

- Make sure the JAVA_POOL_SIZE initialization parameter is set to at least 150 MB.

- Make sure the STREAMS_POOL_SIZE is set to at least 50 MB (200 MB is ideal)

- Ensure there is a value for DB_BLOCK_SIZE

- On Windows operating systems, change the BACKGROUND_DUMP_DEST and USER_DUMP_DEST initialization parameters that point to RDBMS80 or any other environment variable
to point to the following directories instead:

BACKGROUND_DUMP_DEST to ORACLE_BASE/oradata/DB_NAME
and
USER_DUMP_DEST to ORACLE_BASE/oradata/DB_NAME/archive

- Comment out any existing AQ_TM_PROCESSES and JOB_QUEUE_PROCESSES parameter settings, and add new lines in the init.ora/spfile.ora that explicitly set AQ_TM_PROCESSES=0 and JOB_QUEUE_PROCESSES=0 for the duration of the upgrade. The "startup upgrade" command (see step 30) should ensure that these settings are used, but it's worth making sure. 

- If you have defined an UNDO tablespace, set the parameter UNDO_MANAGEMENT=AUTO (otherwise, either unset the parameter or explicitly set it to MANUAL). See Note:135090.1 for further information about the Automatic Undo Management feature.

- Make sure all path names in the parameter file are fully specified. You should not have relative path names in the parameter file.

- If you are using a cluster database, set the parameter CLUSTER_DATABASE=FALSE during the upgrade.

- If you are upgrading a cluster database, then modify the initdb_name.ora  file in the same way that you modified the parameter file.

- Verify the parameter FIXED_DATE is not set.  If it set during the upgrade catalog and catproc will report as invalid even if there are no invalid sys or system objects.  See Note: 745183.1 for further information.

Step 22 :

Check for adequate freespace on archive log destination file systems.

Step 23 :

If needed in your environment, ensure the environment variable NLS_LANG variable is set correctly:
To verify the current setting:
     $ env | grep $NLS_LANG

For additional information on NLS_LANG settings, please refer to the following notes:

Note 158577.1  NLS_LANG Explained (How does Client-Server Character Conversion Work?)
Note 179133.1 The correct NLS_LANG in a Windows Environment
Note 264157.1 The correct NLS_LANG setting in Unix Environments

Step 24:

If needed copy the SQL*Net files like (listener.ora,tnsnames.ora etc)  to the new location (when no TNS_ADMIN env. Parameter is used)

$ cp $OLD_ORACLE_HOME/network/admin/*.ora /network/admin

Step 25:

If your Operating system is Windows (NT, 2000, XP or 2003) delete your services With the ORADIM of your old oracle version.

Stop the OracleServiceSID Oracle service of the database you are upgrading,  where SID is the instance name. For example, if your SID is ORCL, then enter the following at a command prompt:

C:/> NET STOP OracleServiceORCL

For Oracle 8.0 this is:
C:/ORADIM80 -DELETE -SID

For Oracle 8i or higher this is:
C:/ORADIM -DELETE -SID

Also create the new Oracle Database 10gR2 service at a command prompt using the ORADIM command of the new Oracle Database release:

C:/> ORADIM -NEW -SID SID -INTPWD PASSWORD -MAXUSERS USERS
-STARTMODE AUTO -PFILE ORACLE_HOME/DATABASE/INITSID.ORA

Step 26:

Copy configuration files from the ORACLE_HOME of the database being upgraded  to the new Oracle Database 10g ORACLE_HOME:

If your parameter file resides within the old environment's ORACLE_HOME,  then copy it to the new ORACLE_HOME. By default, Oracle looks for the parameter file in ORACLE_HOME/dbs on UNIX platforms and in ORACLE_HOME/database on  Windows operating systems. The parameter file can reside anywhere you wish, but it should not reside in the old environment's ORACLE_HOME after you upgrade to Oracle Database 10g.

If your parameter file is a text-based initialization parameter file with  either an IFILE (include file) or a SPFILE (server parameter file) entry,  and the file specified in the IFILE or SPFILE entry resides within the old  environment's ORACLE_HOME, then copy the file specified by the IFILE or  SPFILE entry to the new ORACLE_HOME. The file specified in the IFILE or SPFILE entry contains additional initialization parameters.

If you have a password file that resides within the old environments  ORACLE_HOME, then move or copy the password file to the new Oracle Database 10g ORACLE_HOME.

The name and location of the password file are operating system-specific.
On UNIX platforms, the default password file is ORACLE_HOME/dbs/orapwsid.
On Windows operating systems, the default password file is
ORACLE_HOME/database/pwdsid.ora. In both cases, sid is your Oracle instance ID.

If you are upgrading a cluster database and your initdb_name.ora file resides  within the old environment's ORACLE_HOME, then move or copy the initdb_name.ora file to the new ORACLE_HOME.

Note:
If you are upgrading a cluster database, then perform this step on all nodes
in which this cluster database has instances configured.

Step 27:

Update the oratab entry, to set the new ORACLE_HOME and disable automatic startup:

SID:ORACLE_HOME:N

Step 28:

Update the environment variables like ORACLE_HOME and PATH

$. oraenv

Step 29:

Make sure the following environment variables point to the new release (10g) directories:

- ORACLE_HOME
- PATH
- ORA_NLS10
- ORACLE_BASE
- LD_LIBRARY_PATH
- LD_LIBRARY_PATH_64 (Solaris only)
- LIBPATH (AIX only)
- SHLIB_PATH (HPUX only)
- ORACLE_PATH

$ env | grep ORACLE_HOME
$ env | grep PATH
$ env | grep ORA_NLS10
$ env | grep ORACLE_BASE
$ env | grep LD_LIBRARY_PATH
$ env | grep ORACLE_PATH

AIX:
$ env | grep LIBPATH

HP-UX:
$ env | grep SHLIB_PATH

Note that the ORA_NLS10 environment variable replaces the ORA_NLS33 environment  variable, so you should unset ORA_NLS33 and set ORA_NLS10.

As per Note:77442.1, you should set ORA_NLS10 to point to $ORACLE_HOME/nls/data

Step 30:

Startup upgrade the database:

$ cd $ORACLE_HOME/rdbms/admin
$ sqlplus / as sysdba
Use Startup with the UPGRADE option:
SQL> startup upgrade

Step 31:

Create a SYSAUX tablespace. In Oracle Database 10g, the SYSAUX tablespace is  used to consolidate data from a number of tablespaces that were separate in  previous releases.

The SYSAUX tablespace must be created with the following mandatory attributes:

- ONLINE
- PERMANENT
- READ WRITE
- EXTENT MANAGEMENT LOCAL
- SEGMENT SPACE MANAGEMENT AUTO

The Upgrade Information Tool(utlu102i.sql in step 4) provides an estimate of the minimum required size for the SYSAUX tablespace in the SYSAUX Tablespace section.

The following SQL statement would create a 500 MB SYSAUX tablespace for the database:

SQL> CREATE TABLESPACE sysaux DATAFILE 'sysaux01.dbf'
SIZE 500M REUSE
EXTENT MANAGEMENT LOCAL
SEGMENT SPACE MANAGEMENT AUTO
ONLINE;

Step 32:

NOTE: Before performing the next action, disable any third party procedures that check the complexity of schema passwords. During the upgrade, new schemas may be created and these may initially have an insecure password (but only for a very short period of time, because the SQL script that creates the new schema will then immediately expire the password and lock the schema). If procedures are in place to enforce password complexity, the "create user" statement may fail and cause configuration of a component to fail.  

Run the catupgrd.sql script, spooling the output so you can check whether any errors occured and investigate them:

SQL> spool upgrade.log
SQL> @catupgrd.sql

The catupgrd.sql script determines which upgrade scripts need to be run and then runs each necessary script. You must run the script in the new release 10.2 environment.

The upgrade script creates and alters certain data dictionary tables. It also upgrades and configures the following database components in the new release 10.2 database (if the components were installed in the database before the upgrade).

Oracle Database Catalog Views
Oracle Database Packages and Types
JServer JAVA Virtual Machine
Oracle Database Java Packages
Oracle XDK
Oracle Real Application Clusters
Oracle Workspace Manager
Oracle interMedia
Oracle XML Database
OLAP Analytic Workspace
Oracle OLAP API
OLAP Catalog
Oracle Text
Spatial
Oracle Data Mining
Oracle Label Security
Messaging Gateway
Expression Filter
Oracle Enterprise Manager Repository

Turn off the spooling of script results to the log file:

SQL> SPOOL OFF

Then, check the spool file and verify that the packages and procedures compiled successfully. You named the spool file earlier in this step; the  suggested name was upgrade.log. Correct any problems you find in this file and rerun the appropriate upgrade script if necessary. You can rerun any  of the scripts described in this note as many times as necessary.

Step 33:

Run utlu102s.sql, specifying the TEXT option:

SQL> @utlu102s.sql TEXT

This is the Post-upgrade Status Tool displays the status of the database  components in the upgraded database. The Upgrade Status Tool displays output similar to the following:

Oracle Database 10.2 Upgrade Status Utility 04-20-2005 05:18:40

Note - in RAC environments, this script may suggest that the status of the RAC component is INVALID when in actual fact it is VALID (as shown in the output from DBA_REGISTRY)

NOTE: As per Note:456845.1, the output from the utlu102s.sql script may differ from the output from DBA_REGISTRY. To check the current status of each component, run the following SQL statement:

SQL> select comp_name, status, version from dba_registry;

Step 34:

Restart the database:
SQL> shutdown immediate (DO NOT use "shutdown abort" !!!)
SQL> startup restrict

Executing this clean shutdown flushes all caches, clears buffers and performs  other database housekeeping tasks. Which is needed if you want to upgrade specific components.

Step 35:

Run olstrig.sql to re-create DML triggers on tables with Oracle Label Security policies.
This step is only necessary if Oracle Label Security is in your database.
(Check from Step 33).

SQL> @olstrig.sql

Step 36:

Run utlrp.sql to recompile any remaining stored PL/SQL and Java code.

SQL> @utlrp.sql

Verify that all expected packages and classes are valid:

If there are still objects which are not valid after running the script run the following:

spool invalid_post.lst
Select substr(owner,1,12) owner,
substr(object_name,1,30) object,
substr(object_type,1,30) type, status
from
dba_objects where status <>'VALID';
spool off

Now compare the invalid objects in the file 'invalid_post.lst' with the invalid objects in the file 'invalid_pre.lst' you create in step 9.

NOTE: If you have upgraded from version 9.2 to version 10.2 and find that the following views are invalid, the views can be safely ignored (or dropped):

SYS.V_$KQRPD
SYS.V_$KQRSD
SYS.GV_$KQRPD
SYS.GV_$KQRSD

You can also ignore or drop the following public synonyms
V$KQRPD
V$KQRSD
GV$KQRPD
GV$KQRSD

As they are based on

SYS.V_$KQRPD
SYS.V_$KQRSD
SYS.GV_$KQRPD
SYS.GV_$KQRSD

NOTE: If you have used OPatch to apply a CPU patch to the 10.2.0.x home, you now need to review and follow the post-installation steps in the README file of the CPU patch to apply the CPU patch to the upgraded database. This may require running the catcpu.sql and other scripts and will vary depending on the version of the CPU installed.

NOTE:  After the upgrade there may be invalid views with the prefix x_$.  These views are created by third party applications and are pointing to non-existent or modified x$ tables.  Third parties should not create SYS owned views, particular not SYS owned views based on internal X$ tables.  Since these are not Oracle created objects, they should be dropped before upgrade, since they cannot be validated or dropped after upgrade using normal methods.

 Additional information can be found in...
Note 361757.1  Invalid x_$ Objects After Upgrade.

 

After Upgrading a Database
Step 37:

Shutdown the database and startup the database.

    % sqlplus '/as sysdba'
    SQL> shutdown
    SQL> startup restrict

Step 38:

Complete the Step 38 only if you upgraded your database from release 8.1.7
Otherwise skip to Step 40.

A) If you are not using N-type columns for user data, ie. the query

    select distinct OWNER, TABLE_NAME
    from DBA_TAB_COLUMNS
    where DATA_TYPE in ('NCHAR','NVARCHAR2', 'NCLOB')
    and OWNER not in ('SYS','SYSTEM','XDB');

did not return rows in Step 6 of this note then:

    % sqlplus '/as sysdba'
    SQL> shutdown immediate

and go to step 40.

B) IF your version 8 NLS_NCHAR_CHARACTERSET was UTF8:

You can look up your previous NLS_NCHAR_CHARACTERSET using this select:

    select * from nls_database_parameters where parameter ='NLS_SAVED_NCHAR_CS';

then:

    % sqlplus '/as sysdba'
    SQL> shutdown immediate

and go to step 40.

C) IF you are using N-type columns for *user* data *AND* your previous NLS_NCHAR_CHARACTERSET was in the following list:

JA16SJISFIXED , JA16EUCFIXED , JA16DBCSFIXED , ZHT32TRISFIXED
KO16KSC5601FIXED , KO16DBCSFIXED , US16TSTFIXED , ZHS16CGB231280FIXED
ZHS16GBKFIXED , ZHS16DBCSFIXED , ZHT16DBCSFIXED , ZHT16BIG5FIXED
ZHT32EUCFIXED

then the N-type columns *data* need to be converted to AL16UTF16:

To upgrade user tables with N-type columns to AL16UTF16 run the script utlnchar.sql:

    % sqlplus '/as sysdba'
    SQL> @utlnchar.sql
    SQL> shutdown immediate;

go to step 40.

D) IF you are using N-type columns for *user* data *AND * your previous NLS_NCHAR_CHARACTERSET was *NOT* in the following list:

JA16SJISFIXED , JA16EUCFIXED , JA16DBCSFIXED , ZHT32TRISFIXED
KO16KSC5601FIXED , KO16DBCSFIXED , US16TSTFIXED , ZHS16CGB231280FIXED
ZHS16GBKFIXED , ZHS16DBCSFIXED , ZHT16DBCSFIXED , ZHT16BIG5FIXED
ZHT32EUCFIXED

then import the data exported in point 8 of this note. The recommended NLS_LANG during import is simply the NLS_CHARACTERSET, not the NLS_NCHAR_CHARACTERSET

After the import:

    % sqlplus '/as sysdba'
    SQL> shutdown immediate;

go to step 40.

Step 39:

If your database has TIMESTAMP WITH TIMEZONE data, you must update  the data so that it is converted and stored based on the new time zone rules that come with the upgrade. (Step 6).

If you used the export utility to export a copy of the affected tables,  you should now use the import utility to import your data from these tables back into your database. The import utility will update the timestamp data as it imports.

If you used the manual script method, you will need to update the affected timestamp data based on your backed up table. For example, if you previously backed up your table, you need to run an update statement similar to the one below to update your timestamp data.

UPDATE tztab t SET t.y =
(SELECT to_timestamp_tz(t1.y,'YYYY-MM-DD HH24.MI.SSXFF TZR')
FROM tztab_back t1
WHERE t.x=t1.x);

Step 40:

Now edit the init.ora:

- If you changed the value for NLS_LENGTH_SEMANTICS from CHAR to BYTE prior to the upgrade (see step 21), set it back to CHAR. Otherwise, do not change the value of the parameter to CHAR without careful evaluation and testing. Switching to CHAR semantics can break application code. See Note:144808.1 for further information about the usage of this parameter.

- If you changed the value for CLUSTER_DATABASE from TRUE to FALSE prior to the upgrade, set it back to TRUE

Step 41:

Startup the database:
SQL> startup

Create a server parameter file with a initialization parameter file
SQL> create spfile from pfile;

This will create a spfile as a copy of the init.ora file located in the
$ORACLE_HOME/dbs directory.

Step 42:

Modify the listener.ora file:
For the upgraded intstance(s) modify the ORACLE_HOME parameter to point to the new ORACLE_HOME.

Step 43:

Start the listener
$ lsnrctl
LSNRCTL> start

Step 44:

Enable cron and batch jobs

Step 45:

Change oratab entry to use automatic startup
SID:ORACLE_HOME:Y

Step 46:

Upgrade the Oracle Cluster Registry (OCR) Configuration.
If you are using Oracle Cluster Services, then you must upgrade the Oracle Cluster Registry (OCR)keys for the database.

* Use srvconfig from the 10g ORACLE_HOME. For example:

% srvconfig -upgrade -dbname <db_name> -orahome <pre-10g_Oracle_home>

If the output from the $ORACLE_HOME/bin/ocrdump command references the pre-10g home, it may be necessary to do the following:

From the pre-10g home, run the command:

% svrctl remove database -d <db_name>

From the 10g home, run the commands:

% srvctl add database -d <db_name> -o <10g_Oracle_home>
% srvctl add instance -d <db_name> -i <instance1_name> -n <node1>
% srvctl add instance -d <db_name> -i <instance2_name> -n <node2>

Step 47:

Use the DBMS_STATS package to gather new statistics for your user objects. Using statistics collected from a previous Oracle version may lead CBO to generate less optimal execution plans.

SQL> EXEC DBMS_STATS.GATHER_DICTIONARY_STATS ;

Note:114671.1 "Gathering Statistics for the Cost Based Optimizer"
Note:262592.1 "How to tune your Database after Migration/Upgrade"

Step 48:

Enterprise Manager Grid Control (EMGC) will show that the upgraded database does not have an inventory. To re-discover the database, do the following:

1. Go to EMGC => Targets => Databases

2. Select the upgraded database and remove it

3. Click "Add", enter the name of the host and click "Continue" to allow EMGC to re-discover
the database in the correct home with the correct inventory

Useful Hints
** Upgrading With Read-Only and Offline Tablespaces (Database must be in archive log mode)

The Oracle database can read file headers created prior to Oracle 10g, so you do not need to do anything to them during the upgrade. The only exception to this is if  you want to transport tablespaces created prior to Oracle 10g, to another platform.  In this case, the file headers must be made read-write at some point before the transport.  However, there are no special actions required on them during the upgrade.

The file headers of offline datafiles are updated later when they are brought online,  and the file headers of read-only tablespaces are updated if and when they are made read-write sometime after the upgrade. In any other circumstance, read-only tablespaces never have to be made read-write.

To decrease the time needed for a recovery in case of issues with the migration, users can OFFLINE NORMAL all user or application created tablespaces prior to migration. This way if migration fails only the Oracle created tablespaces and rollback datafiles need to be restored rather than the entire database.

You can not OFFLINE any Oracle created tablespaces including those containing rollback/UNDO tablespace prior to migration.

Note: You must OFFLINE the TABLESPACE as migrate does not allow OFFLINE files  in an ONLINE tablespace.

Note: If you are upgrading from Oracle9i, the CWMLITE tablespace (which contains OLAP objects) will need to be ONLINE during the upgrade (so that the OLAP objects can be upgraded to 10g and moved to the SYSAUX tablespace)

** Converting Databases to 64-bit Oracle Database Software

If you are installing 64-bit Oracle Database 10g software but were previously  using a 32-bit Oracle Database installation, then the databases will automatically be converted to 64-bit during the upgrade to Oracle Database 10g except when upgrading from Release 1 (10.1) to Release 2 (10.2).

The process is not automatic for the release 1 to release 2 upgrade, but is automatic for all other upgrades. This is because the utlip.sql script is not run during the release 1 to release 2 upgrade to invalid all PL/SQL objects. You must run the utlip.sql script as the last step in the release 10.1 environment, before upgrading to release 10.2.

** If error occurs while executing the catupgrd.sql

If an error occurs during the running of the catupgrd.sql script, once the problem is fixed you can simply rerun the catupgrd.sql script to finish the upgrade process and complete the
the upgrade process.

Known issues
1)   While doing a upgrade from 9iR2 to 10.2.0.X.X, on running the utlu102i.sql  script as directed in step 2
Its output informs to add streams_pool_size=50331648 to the init.ora file. While adding the parameter Oracle gives streams_pool_size as invalid parameter.

STREAMS_POOL_SIZE, was introduced in release 10gR1.  This message may be ignored for database version 9iR2 or less

2) One of the customer has reported on keeping the shared_pool_size at 150 MB, catmeta.sql fails with insuffient shared memory during the processing of view KU$_PHFTABLE_VI.

Please set the shared_pool_size at 200M.

3) While upgrade following error was encountered.
create or replace
*
ERROR at line 1:
ORA-06553: PLS-213: package STANDARD not accessible.
ORA-00955: name is already used by an existing object

Please make sure to set the following init parameters as below in the spfile/init file or comment them out to their default values, at the time of upgrading the database.

PLSQL_V2_COMPATIBILITY = FALSE
PLSQL_CODE_TYPE = INTERPRETED # Only applicable to 10gR1
PLSQL_NATIVE_LIBRARY_DIR = ""
PLSQL_NATIVE_LIBRARY_SUBDIR_COUNT = 0

Refer to Note 170282.1 PLSQL_V2_COMPATIBLITY=TRUE causes STANDARD and DBMS_STANDARD to Error at Compile

@

Always disconnect from the session which issues the STARTUP and connect as a fresh session before doing any further SQL. eg: On upgrade to 10.2 startup the instance with the upgrade option, exit sqlplus , reconnect a fresh SQLPLUS session as SYSDBA and then run the upgrade scripts.

If this is not a RAC instance, but DBA_REGISTRY shows the RAC component and it is invalid the following bite can be used to remove the reference from  DBA_REGISTRY.

NOTE:312071.1 - RAC Option Invalid After Migration

5) Upgrade log shows process errors with ORA-28031 "maximum of 148 enabled roles" when creating queue table.

The number of DEFINED roles (enabled and disabled) that SYS has must not exceed the maximum number of roles defined for the database as defined by the instance parameter max_enabled_roles.

To correct, reduce the number of DEFINED roles to less then 148 then re-run the catupgrd.sql script.

Symptoms

 

After applying a 10.1 or a 10.2 patchset and running catpatch.sql (10.1)  or catupgrd.sql (10.2) the following error is received:

select dbms_java.full_ncomp_enabled from dual
*
ERROR at line 1:
ORA-29558: JAccelerator (NCOMP) not installed. Refer to Install Guide for
instructions.
ORA-06512: at "SYS.DBMS_JAVA", line 236

 

Or if during the running of the utlu102i.sql script you are warned that the JAccelerator (NCOMP) is not installed.

Cause
The Oracle Companion CD was either not installed or specifically the Natively Compiled Java Libraries (NCOMP) were not installed.

The Installation documentation is not explicit; however, the NCOMPs are optional and the error, ORA-29558 is informational not an actual error.  NCOMPs do not have to be installed and the error can be ignored.  The drawback is the potential of slower performance due to javabyte code having to be translated into machine code when used, but has no effect on an upgrade or migration.  The Database Upgrade Assistant (DBUA) and the utility script utlu102i.sql will show that the NCOMPs are not installed but it will not affect the upgrade or migration.

Also, for clarification purposes, an Oracle Application Server 10g, version 10.1.2.0.2 Metadata Repository installation, JAccelerator (NCOMP) is not used for the Oracle Applicaton Server.

Solution
 Video - [The installation steps available in Video] (04:57) 
If you wish to address the informational message (ORA-29558) and install the NCOMPs then follow these steps:

Note: If you have one-off patches on top of a 10.1.0.x or 10.2.0.x patchset they do NOT need to be rollback and reapplied, they can remain.

1) You will need to install Natively Compiled Java Libraries (NCOMP) from the 10.1 or 10.2 Companion CD depending on your base release, for 10.1 please refer to 10.1 Companion CD Guide for Unix for specific details and for 10.2 refer to your OS platform specific Companion CD Installation Guide

2) Start up the runInstaller once again and select the 10.1 or 10.2 patchsets products.xml file once again in the "Specify File Locations" screen. The OUI will see the new components installed and only install the 10.1 or 10.2  patches associated to the new products.

3) Click on 'Install' on the Summary Screen (There should be roughly 29 items that are being installed)

4) After this then re-run catpatch (10.1) or catupgrd (10.2) once again and this will correct the situation.

Otherwise, the only other way would be to deinstall the software via the OUI and then reinstall 10.1 or 10.2 then install NCOMP via the Companion CD and then install 10.1 or 10.2 patchset depending on your base release version.
