Oracle 19.3 dataguard环境下同步新增pdb

备库相关的pdb_test01文件为offline状态，该pdb为mounted状

备份新增pdb（主库端执行）

BACKUP as compressed backupset incremental level 0 PLUGGABLE DATABASE pdbXXXX;

使备库待恢复pdb_test01处于disable recovery状态，不影响现有备库其他pdb进行mgr日志应用（备库端执行)

alter PLUGGABLE DATABASE pdb_test01 disable recovery;

SELECT name, open_mode, recovery_status FROM v$pdbs

备库执行单个pdb恢复（备库端执行）,数据库恢复操作：

catalog start with '/backup‘；

restore PLUGGABLE DATABASE pdbXXXX;

恢复完执行新增同步pdb enable recover

SELECT name, open_mode, recovery_status FROM  v$pdbs;
alter session set container=pdb_test01
alter pluggable database pdb_test01 enable recovery;
alter database recover managed standby database using current logfile disconnect from session;
