Oracle 12c nocdb轉(zhuǎn)換成cdb

環(huán)境說明：

OS:Oracle Linux Server release 6.3

DB:Oracle 12.2.0.1.0

DBName:dapuchai

場景：

Oracle 11.2.0.4.0升級到Oracle 12.2.0.1.0，默認是no-cdb模式，升級后根據(jù)需要將no-cdb轉(zhuǎn)換成cdb里，即將之前的11.2.0.4.0數(shù)據(jù)完全遷移到PDB(Creating a PDB Using a Non-CDB)；

實施方案：

一：連接non-CDB(dapuchai)，生成XML格式數(shù)據(jù)庫描述文件

二：DBCA新建cdb數(shù)據(jù)庫(cjcdb)

三：Plug in the non-CDB (cjcpdb)

四：執(zhí)行noncdb_to_pdb.sql

五：驗證數(shù)據(jù)

參考：https://docs.oracle.com/database/121/ADMIN/cdb_plug.htm#ADMIN13598

一： 連接non-CDB(dapuchai)，生成XML格式數(shù)據(jù)庫描述文件

Connect to the non-CDB, and run the DBMS_PDB.DESCRIBE procedure to construct an XML file that describes the non-CDB.

[root@cjc ~]# ps -ef|grep pmon

oracle    2677     1  0 22:35 ?        00:00:00 ora_pmon_dapuchai

---生成xml格式的數(shù)據(jù)庫描述文件

SQL> BEGIN

  DBMS_PDB.DESCRIBE(pdb_descr_file => '/home/oracle/20200113.xml');

END;  2    3 

  4  /

PL/SQL procedure successfully completed.

二：DBCA新建cdb數(shù)據(jù)庫(cjcdb)

[oracle@cjc ~]$ dbca

三：Plug in the non-CDB (cjcpdb)

[oracle@cjc oracle12]$ ps -ef|grep pmon

oracle    3106     1  0 22:38 ?        00:00:00 ora_pmon_dapuchai

oracle    5651  3249  0 23:16 pts/1    00:00:00 grep pmon

[oracle@cjc ~]$ export ORACLE_SID=cjcdb
