Summary:-

 

This document contains the steps of  SAP oracle upgrade 10G to 11G on AIX (Operating system) using oracle DBUA menthod.

 

Author: Brindavan Mookaiah

Designation: SAP BASIS Consultant

 

Pre-requisite steps


Backup


  1) Before starting the ORACLE Upgrade 11g please take the backup of ORACLE_HOME (102_64) and oraInventory folder.

 

  2) /oracle/SID/102_64 -- Please take backup of entire 102_64 folder to some secured location.


  3) /oracle/SID/oraInventory -- Please take the backup of entire oraInventory folder to some secured location.

 

   4)  Before starting the upgrade make sure you have run a FULL ONLINE backup of the database

 

Filesystem and Tablespace

 

      1) Check  the for ‘CIO’ option.

 

      2) File system need space “/oracle/stage” -- Needs to be mounted with enough space (around 15GB)

 

      3) Filesystem need space” oracle//11203” --  Needs to be mounted with enough space (around 12GB)

 

      4) If you are mounting the ORACLE_HOME filesystem with /oracle//11203 then please create a softlink of /oracle//112_64 linking to            /oracle//11203  with oraas follows: ln –s  /oracle//11203  112_64

 

  4) Export TEMP_DIR to a filesystem which has enough space (around 5GB).

 

  5) Extend  SYSTEM TABLESPACE & SYSAUX TABLESPACE (Mandatory) Enough space of around 2 GB in SYSAUX and  around 3GB in SYSTEM TABLESPACE)

 

 

Filesystem

 

Steps 1

 

Stop SAP appliaction

 

 

Login into OS level with root or oraSID user.

 

Check  the for ‘CIO’ option in all filesystem started with "/oracle".

 

All the above filesystem’s “options” should be WITHOUT “CIO” option. If it’s with CIO option than the upgrade to oracle 11g or the oracle patch set upgrade will fail at the time of relinking of the binaries phase. This is only specific to IBM AIX systems.

 

Check the oracle environment variable for oracle. use Echo command like


ORASID> echo $ ORACLE_HOME

ORASID> echo $ ORACLE_BASE

ORASID> echo $ ORACLE_SID



Now change the environment variable like below command  with orasid user.


Execute the below command


Export  ORACLE_HOME_SRC & ORACLE_HOME_TGT as below

 

export ORACLE_HOME_SRC=/oracle/SID/102_64

export ORACLE_HOME_TGT=/oracle/SID/11203

export  TEMP=/oracle/stage/11203/tmp

 


In AIX we need to run the “rootpre.sh” script as shown below before running the actual upgrade and should fix the possible error if any as per the logs.


You can find the rootpre.sh script in the extracted oracle software folder (“/11203/database”)


We have added the user “oraSID” into the group “hagsuser” and again run the script.

Below screen shows the group subsystems service is not active. We have to ask Unix guy to start the services.


 

Now run the ./RUNINSTALLER from ora user as shown in below screen. From the location /oracle/stage/11203/database/SAP



 

Click Next

 

 

 

Click Yes

 

 

 

Select Skip option and then click Next

 

Select option Upgrade an existing database and click Next

 

Click Next

 

 

Select Enterprsie Edition and then click Next

 

 

Click Next

 

 

Click on YES and continue.


Keep the defaults and Click Next

 

 

Click on “Fix and Check again” to fix the Warnings.


 

After click on OK button the prerequisite check will run again.

We had the below check which failed in 2nd run.


 

 

All these are “Warning” we decided to continue with this by selecting Ignore all button as shown below.


Click Next

 

 

Click Install

 

 

Login into OS level with root user and run the "root.sh"

After running the root.sh script as shown from the above location click on the OK button on the above screen.

 

Before executing the root.sh script please take a copy of all the three files (dbhome, oraenv, coraenv)

 

cp -pr  dbhome  dbhome.original

cp -pr  oraenv  oraenv.original

cp -pr  coraenv  coraenv.original

 

 

 

Then continue from the point of stop,click on ok

 

 

select" Perform typical configuration" and click Next

 

Before pressing Next please check below:

 

Running the Pre-Upgrade Scripts

 

You run the Oracle pre-upgrade scripts, which automatically perform various tasks and checks on your database. See SAP Note 1431793.

This section only applies if your source database is Oracle 10.2.0.410.2.0.5, or 11.2.0.1. The scripts do the following on your pre-upgrade database:

Provide information on the database

Suggest any changes that you need to make to the database before you start the upgrade

Perform some of the pre-upgrade tasks on the database

 

NOTE

You always execute these scripts as the ora user connected to the database as sysdba in the Oracle 10.2 environment.

 

Prerequisites

You are logged on as user ora in the Oracle 10.2 environment with the database also started up.

The directory where the upgrade scripts are installed is called ora_upgrade.

By default, the scripts are installed as part of the SAP bundle patch in the relevant Oracle 11.2 software home directory:

 

64-bit: /oracle//112_64/sap/ora_upgrade

32-bit: /oracle//112_32/sap/ora_upgrade

 

OR

 

You need to download it from the latest SAP bundle patch on service market place.

 

 

Procedure

Change to the correct directory by entering the relevant command (since the scripts have been extracted to the Oracle 11.2 software home):

64-bit: cd /oracle//112_64/sap/ora_upgrade/pre_upgrade

32-bit: cd /oracle//112_32/sap/ora_upgrade/pre_upgrade

 

Execute the following commands to check the pre-upgrade status of your database:

sqlplus / as sysdba

SQL> @pre_upgrade_status.sql

 

Execute the following commands to perform pre-upgrade tasks, which can improve the performance of the upgrade process:

sqlplus / as sysdba

SQL> spool pre_upgrade_tasks.log

SQL> @pre_upgrade_tasks.sql

SQL> spool off

 

 

Result

You can check the results of the pre-upgrade scripts by looking at the following log files:

pre_upgrade_status.log

pre_upgrade_tasks.log

 

You can run the pre-upgrade scripts as often as you like on the pre-upgrade Oracle 10.2 database.

 

CAUTION

Make the changes listed in the log file, otherwise you might have problems during the upgrade. However, you must ignore the warning regarding the database parameter remote_os_authent, which is reported as DEPRECATED.

Do not touch this parameter. The post-upgrade script sets it to TRUE again after the database upgrade. This parameter must be set to TRUE for the SAP logon mechanism to work correctly after the database upgrade.


IF YOU CANNOT FIND SAP FOLDER IN ORACLE_HOME FOR THE PRE-UPGRADE & POST-UPGRADE SCRIPTS THEN PLEASE REFER NOTE: Note 1431793 - Oracle 11.2.0: Upgrade Scripts

 

As of 2012-Jun-22 the scripts are included in the patch 9584028 updated for release 11.2.0.3.

You can find the above patch 9584028 in the current SAP Bundle Patch file located  in service market place http://www.service.sap.com

Download the above latest SAP Bundle Patch on your local machine extract on your server host


Loginto into oslevel with orasid and login to sql



The following scripts are provided for the database upgrade of an SAP/Oracle database:

 

  Pre-Upgrade-Scripts

 

  create_restore_point.sql  --  (Not required to do this step)

 

This script lets you create a guaranteed restore point before the upgrade.

Creating a guaranteed restore point enables you to flashback the database. This feature is useful especially during upgrade testing to quickly reset the database. For more information about FLASHBACK DATABASE, see SAP note 966117.

 

The use of this script is optional.

 

pre_upgrade_checks.sql

 

This script contains database pre-upgrade checks.

 

Run this script before the upgrade.

 

  pre_upgrade_status.sql

 

This script performs pre-upgrade checks, the result is written into a log file.

 

Run this script before the upgrade.

  pre_upgrade_tasks.sql

 

This script contains database pre-upgrade tasks like recompile invalid objects or gather Oracle Dictionary Statistics to reduce the number of warnings in the pre-upgrade check and to improve upgrade performance (minimize upgrade time).

 

Run this script before the upgrade.

 

  utlu112i.sql

 

Oracle Pre-Upgrade Information Utility

 

(My Oracle Support article 884522.1)

  utlu112i_sap.sql

 

Oracle Pre-Upgrade Information Utility for SAP

This script is run when running pre_upgrade_checks.sql or pre_upgrade_status.sql.

 

Once the script are completed then go back the DBUA and then click next

 

 

 

Click Yes

 

Select “Recompile invalid objects at the end of upgrade” & “Upgrade Timezone Version and TIMESTAMP WITH TIME ZONE Data”. Click NEXT


Click Yes

 

 

Click Next

 

 

Click Next

 

Unselect the above “Configure the Database with Enterprise Manager” option


 

 

KEEP AN EYE ON ORAARCH DIRECTORY AFTER YOU PRESS FINISH (DURING STARING OF THE ORACLE UPGRADE PROCESS)

 

Click ok

 

 

Click Close

 

 

Click close

 

 

 

From Oracle 11g the Runtime Oracle_Home should point to /oracle//112_64 and the Installation Oracle_Home should point to /oracle//11203



Please change the below profile parameters so that it points to 112_64

Change from 102_64 to 112_64

 

grep -R 102_64 /oracle/CS8/ --  to search for 102_64 in all the profiles

grep -R 102_64 /home/cs8adm --  to search for 102_64 in all the profiles

 

Command to change in profile parameter files

:1,$s/102_64/112_64/g


 

You might need to change on below parameters as well based on the list which is present.


After the above changes ORACLE_HOME is pointing to /oracle//112_64. So export the oracle home to /oracle//11203 and shutdown the database because the database is still running with 11203 installation home.


oracSID> export ORACLE_HOME=/oracle/SID/11203


oracSID> sqlplus / as sysdba

APPLYING SBP

With ORACS8 user

 

Make a copy of the original MOPatch OPatch

 

Copy the MOPatch and OPatch folder from the SBP folder to /oracle/SID/112_64


export PATH=$PATH:/oracle/SID/112_64/OPatch

 

Copy mopatch.sh from /oracle/SID/112_64/MOPatch to /oracle/SID/112_64



You have to zip the SBP folder as the mopatch.sh only recognizes the zip folder of SBP in order to extract the required patches from it and install it into ORACLE_HOME.


 

 

Installing the SAP Bundle Patch

Follow the steps below.

  1. 1.       Stop all database applications, in particular all SAP applications.
  2. 2.       Shut down the database instances, the listeners, and other processes associated with the Oracle Home.
  3. 3.       After having shut down all database processes as described in the previous step, use thefuser OS command to check for stale SQL*Plus sessions

   $SBPFUSER $OHRDBMS/bin/oracle

If that command reports running processes, these are stale SQL*Plus sessions, which you can safely terminate with the kill command

  1. 4.       For IBM AIX on POWER Systems only:

Run the slibclean command under /usr/sbin as super user:

#temporarily change to super user

      su root -c slibclean

 

 

SQLPLUS> SHUTDOWN IMMEDIATE;

 

TEST MODE:

/bin/sh $ORACLE_HOME/mopatch.sh -v -d -s /oracle/stage/11203/ORACLE_11_2_0_3_Upgrade_Media/SAP_112031_201203.zip

 

ACTUAL SBP RUN COMMAND:

/bin/sh /oracle/SID/112_64/mopatch.sh -v -s

/dbexport_ecc/Oracle11g_media_AIX/ SAP_112033_201209_AIX.zip



Run

opatch lsinventory

from the path /oracle/SID/11203/OPatch to check whether patches are applied or not.

 

 

 

 

POST STEPS AFTER APPLYING SBP

 

 

The post steps described here are based on SBP level SAP Bundle Patch 11.2.0.3.2 – 201206

 

 

Check the generated MOPatch report for errors or unresolved conflicts. To resolve them, refer to section "Resolving Patch Conflicts and Errors" of SAP Note 1027012 MOPatch - Install Multiple Oracle Patches in One Run.

 

 

Start up the database instances, the listeners, and other processes associated with the Oracle Home.

 

 

For each database instance running from the Oracle home*, connect to the database instance as SYSDBA using SQL*Plus and run the post-installation script catsbp.sql:

 

 

  $ cd /oracle/SID/11203/rdbms/admin

  $ sqlplus / as sysdba

  SQL> @/oracle/SID/11203/sapbundle/SBP_112032_201206/catsbp.sql

  SQL> quit

 



Executing Post-Installation Instructions

 

 

Follow the instructions listed below after installation of this SAP Bundle Patch. Except when otherwise stated, execute the instructions after starting the database instances.

Patch 13943375 (CBO Merge Patch), added in SBP 11.2.0.3.2 201205

Please use the following statements to adjust your _fix_control and event

settings in your spfile according to SAP note 1431798 with the new SBP:

 

 

ALTER SYSTEM SET "_FIX_CONTROL"=

'5099019:ON','5705630:ON','6055658:OFF','6399597:ON','6430500:ON','6440977:ON',

'38087',

'44951 level 1024',

'31991'

COMMENT='SAP_112030_201112 RECOMMENDED SETTINGS'

SCOPE=SPFILE;

 

 

Please restart the database after you have adjusted these parameters.

 

 

Patch 13575265, added in SBP 11.2.0.3.1 201203

For Database Vault systems, if Database Vault is already installed,

run the following script (for RAC systems, run the script on one of the nodes):

 

 

sqlplus / as sysdba                                                    

spool patch_13575265.log                                          

@/oracle/SID/11203/rdbms/admin/prvtlbac.plb                                       

spool off                                                         

exit  

 

 

The following error message can be ignored:

'ORA-00955: name is already used by an existing object'

Execute utlrp

  @/oracle/SID/11203/rdbms/admin/utlrp.sql.

 

 

 

 

Now all of the above steps are done hence shutdown and startup the database

 

 

 

 

 

 

Just to add in the end and to avoid problem if occurred regarding listener.

 

 

Please do the following to avoid any listener pointing problems for oracle 11g database.

 

 

Edit the Listener.ora file

The listerner.ora file contains server side network configuration parameters. It can be found in the "$ORACLE_HOME/network/admin" directory on the server.

e.g.: /oracle/SID/11203/network/admin/listener.ora

 

 

Add the below extra lines in listener.ora file

 

 

SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (GLOBAL_DBNAME = SID.WORLD)

      (ORACLE_HOME = /oracle/SID/11203)

      (SID_NAME = SID)

    )

  )

--------------------------------------------------------------------------------------------------------------------------------

 

 

Now do the below to avoid ORACLE error “ORA-28002: the password will expire within string days”

 

 

On SQLPLUS level please perform the below steps to set “PASSWORD_LIFE_TIME” from “180” to “UNLIMITED”

 

 

SQL> select resource_name,resource_type, limit from dba_profiles where profile='DEFAULT';

 

 

The above query will give the output something like below:

 

 

RESOURCE_NAME                    RESOURCE LIMIT

-------------------------------- -------- ----------

COMPOSITE_LIMIT                  KERNEL   UNLIMITED

SESSIONS_PER_USER                KERNEL   UNLIMITED

CPU_PER_SESSION                  KERNEL   UNLIMITED

CPU_PER_CALL                     KERNEL   UNLIMITED

LOGICAL_READS_PER_SESSION        KERNEL   UNLIMITED

LOGICAL_READS_PER_CALL           KERNEL   UNLIMITED

IDLE_TIME                        KERNEL   UNLIMITED

CONNECT_TIME                     KERNEL   UNLIMITED

PRIVATE_SGA                      KERNEL   UNLIMITED

FAILED_LOGIN_ATTEMPTS            PASSWORD 10

PASSWORD_LIFE_TIME               PASSWORD 180

 

RESOURCE_NAME                    RESOURCE LIMIT

-------------------------------- -------- ----------

PASSWORD_REUSE_TIME              PASSWORD UNLIMITED

PASSWORD_REUSE_MAX               PASSWORD UNLIMITED

PASSWORD_VERIFY_FUNCTION         PASSWORD NULL

PASSWORD_LOCK_TIME               PASSWORD UNLIMITED

PASSWORD_GRACE_TIME              PASSWORD UNLIMITED

 

 

 

 

Now fire the below SQL command to set parameter “PASSWORD_LIFE_TIME” TO “UNLIMITED”

 

 

SQL> ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;

SQL> commit;
