Oracle 12c nocdb转换成cdb

环境说明：

OS:Oracle Linux Server release 6.3

DB:Oracle 12.2.0.1.0

DBName:dapuchai

场景：

Oracle 11.2.0.4.0升级到Oracle 12.2.0.1.0，默认是no-cdb模式，升级后根据需要将no-cdb转换成cdb里，即将之前的11.2.0.4.0数据完全迁移到PDB(Creating a PDB Using a Non-CDB)；

实施方案：

一：连接non-CDB(dapuchai)，生成XML格式数据库描述文件

二：DBCA新建cdb数据库(cjcdb)

三：Plug in the non-CDB (cjcpdb)

四：执行noncdb_to_pdb.sql

五：验证数据

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

Oracle 12c nocdb怎么转换成cdb

一：连接non-CDB(dapuchai)，生成XML格式数据库描述文件

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

root 3057 2634 0 22:37 pts/1 00:00:00 grep pmon
