25.5.3.4 Duplicating a PDB to a New CDB

初始化环境准备
克隆pdb01 到新的cdb test1.
1.配置test1静态监听

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = test1)
    )
  )

LISTENER =
  (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP)(HOST = db02)(PORT = 1521))

2，配置test1 启动参数文件

//test1配置auxiliary instance
inittest1.ora
*.db_name='test1'
*.enable_pluggable_database=true

3，启动test1到nomount状态

[oracle@db02 dbs]$ export ORACLE_SID=test1
[oracle@db02 dbs]$ sqlplus / as sysdba
