-----ORACLE12.2 升級之路 之 08(11.2.0.4本機升級12.2.0.1后插入PDB)-----
#升级后数据库信息
SQL> select cdb,NAME,dbid from v$database;
CDB NAME DBID
--------- --------------------------- ----------
NO MPACC 3165604684
CDB数据库信息
SQL> startup
SQL> select * from v$version;
Oracle Database 12c Enterprise Edition Release 12.1.0.1.0 - 64bit Production 0
CORE 12.1.0.1.0 Production 0
SQL> show pdbs;
SQL> select con_id,dbid,NAME,OPEN_MODE from v$pdbs;
no rows selected
二、查看表空间及数据文件信息：
SQL> select * from v$tablespace;
0 SYSTEM YES NO YES 0
1 SYSAUX YES NO YES 0
2 UNDOTBS1 YES NO YES 0
4 USERS YES NO YES 0
3 TEMP NO NO YES 0
SQL>
set line 300
col file_name format a40
col tablespace_name format a10
select tablespace_name,file_name from dba_data_files;
TABLESPACE FILE_NAME
---------- ----------------------------------------
SYSTEM /u01/app/oracle/oradata/MPACC/system01.dbf
UNDOTBS1 /u01/app/oracle/oradata/MPACC/undotbs01.dbf
SYSAUX /u01/app/oracle/oradata/MPACC/sysaux01.dbf
USERS /u01/app/oracle/oradata/MPACC/users01.dbf
TABLESPACE FILE_NAME
---------- ----------------------------------------
三、创建用于生成PDB的XML文件
SQL>
shutdown immediate
startup mount
alter database open read only;
SQL> exec dbms_pdb.describe(pdb_descr_file => '/home/oracle/mpacc.xml');
SQL> host ls -rtl /home/oracle/mpacc.xml
-rw-r--r-- 1 oracle oinstall 7237 Aug 31 17:34 /home/oracle/mpacc.xml
SQL> set serveroutput on;
SQL>
declare
compat boolean := FALSE;
begin
compat := dbms_pdb.check_plug_compatibility(pdb_descr_file => '/home/oracle/mpacc.xml');
if compat then
dbms_output.put_line('YES');
else
dbms_output.put_line('No');
end if;
end;
/
--------------------------------------------------------------------------
ERROR at line 1:
ORA-65090: operation only allowed in a container database
ORA-06512: at "SYS.DBMS_PDB", line 24
ORA-06512: at line 4
----------------------------------------------------------------------------
SQL> select name from v$database;
NAME
---------------------------
MPACC
SQL> shutdown immediate;
创建CDB数据库
5.1 执行dbca创建cdb数据库
查看当前pdb信息
[oracle@db01 ~]$ export ORACLE_SID=MPCDB
SQL> show pdbs;
2 PDB$SEED READ ONLY NO
3 PDB01 READ WRITE NO
SQL> select con_id,dbid,NAME,OPEN_MODE from v$pdbs;
2 1952393588 PDB$SEED READ ONLY
3 3441784768 PDB01 READ WRITE
SQL> set serveroutput on;
SQL>
declare
compat boolean := FALSE;
begin
compat := dbms_pdb.check_plug_compatibility(pdb_descr_file => '/home/oracle/mpacc.xml');
if compat then
dbms_output.put_line('YES');
else
dbms_output.put_line('No');
end if;
end;
/
--------------------------
No
---------------------------
七、将non-cdb数据库插入到cdb中成为一个pdb
SQL> show parameter compatible;
NAME TYPE VALUE
------------------------------------ ---------------------------------
compatible string 12.2.0
noncdb_compatible boolean FALSE
SQL> alter system set compatible='12.2.0.1.0' scope=spfile;
重啟db
SQL> CREATE PLUGGABLE DATABASE MPACC USING '/home/oracle/mpacc.xml' NOCOPY;
CREATE PLUGGABLE DATABASE MPACC USING '/home/oracle/mpacc.xml' NOCOPY
*
ERROR at line 1:
ORA-27038: created file already exists
ORA-01119: error in creating database file
'/u01/app/oracle/oradata/MPACC/temp01.dbf'
[oracle@XAG140 ~]$ rm /u01/app/oracle/oradata/MPACC/temp01.dbf;
SQL> CREATE PLUGGABLE DATABASE MPACC USING '/home/oracle/mpacc.xml' NOCOPY;
九、插入完成后查看pdbs信息
SQL> show pdbs;
SQL> select NAME,OPEN_MODE from v$pdbs;
PDB$SEED READ ONLY
PDB01 MOUNTED
MPACC MOUNTED
SQL> alter pluggable database MPACC open;
Warning: PDB altered with errors.
SQL> show pdbs;
2 PDB$SEED READ ONLY NO
3 PDB1 MOUNTED
4 MPACC READ WRITE YES
十、执行noncdb_pdb脚本
SQL> alter session set container=MPACC;
SQL> show pdbs;
CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
4 MPACC READ WRITE YES
SQL> shutdown immediate;
SQL> @$ORACLE_HOME/rdbms/admin/noncdb_to_pdb.sql
更新完之后需要同步pdb信息
SQL> show pdbs;
CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
5 MPACC MOUNTED
SQL> alter pluggable database open restricted;
SQL> show pdbs;
CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
5 MPACC READ WRITE YES
SQL> exec dbms_pdb.sync_pdb();
SQL> alter pluggable database close immediate;
SQL> alter pluggable database open;
确定no-cdb plug cdb 成功
[oracle@XAG140 database]$ sqlplus / as sysdba
SQL> show pdbs;
2 PDB$SEED READ ONLY NO
3 PDB01 MOUNTED
5 MPACC READ WRITE NO
到这里已经完全完成了11.2.0.4数据库插入到12.1.0.1中,实现把11GR2转化为CDB数据库中的一个PDB
說明：臨時表空間需要重新整理（默認添加的比較小）
