SOLUTION

PDB instance_name ‘wd1‘ will always exists within in the CDB instance_name ‘ct1‘. Configure the SID for PDB service name wd1 has shown below.

SID_LIST_LSNRPD =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = ct1)
(ORACLE_HOME = d:\orasfw\prd1)
(SID_NAME = ct1)
)
(SID_DESC =
(GLOBAL_DBNAME = wd1) <<<< PDB Instance_name
(ORACLE_HOME = d:\orasfw\prd1)
(SID_NAME = ct1) <<<< CDB Instance_name
)
)

---实际操作过程

---停 OGG
stop mgr
stop *

--停DG

--主库
alter system set log_archive_dest_state_2=defer;

---备库取消应用
alter database recover managed standby database cancel;

2.停监听
