18c dataguard主库添加pdb导致从库报错误

1.主库添加了pdb
SQL> create pluggable database pdb5 admin user jiangt identified by "oracle";

Pluggable database created.

SQL> alter pluggable database pdb5 open;

Pluggable database altered.

 

2.从库报如下错误

这个时候从库的mgr进程也是自动停掉了。

 

3.找到主库新增的pdb5对应的文件

SQL> column con_id format 99;
SQL> column guid format a32;
SQL> column pdb_name format a8;
SQL> column file_id format 99;
SQL> column file_name format a100;
SQL> select a.CON_ID, a.guid, a.name as pdb_name, b.FILE# as file_id, b.NAME as file_name
  2    from v$pdbs a, v$datafile b
  3   where a.CON_ID = b.CON_ID
  4     and a.name='PDB5';

CON_ID GUID                             PDB_NAME FILE_ID FILE_NAME
------ -------------------------------- -------- ------- ----------------------------------------------------------------------------------------------------
     7 C34A5522517E2082E0536F38A8C01CFA PDB5          34 +DATA/SLNNGK/C34A5522517E2082E0536F38A8C01CFA/DATAFILE/system.434.1073613013
     7 C34A5522517E2082E0536F38A8C01CFA PDB5          35 +DATA/SLNNGK/C34A5522517E2082E0536F38A8C01CFA/DATAFILE/sysaux.435.1073613013
     7 C34A5522517E2082E0536F38A8C01CFA PDB5          36 +DATA/SLNNGK/C34A5522517E2082E0536F38A8C01CFA/DATAFILE/undotbs1.433.1073613013

 

 4.从库修改db_file_name_convert参数

SQL> create pfile='/tmp/pfile.txt' from spfile;
找到db_file_name_convert对应的项(注意不能换行)
*.db_file_name_convert='+DATA/slnngk/datafile/','/u01/app/oracle/oradata/ora18c/','+DATA/slnngk/tempfile/','/u01/app/oracle/oradata/ora18c/','+data/slnngk/C21CCC2F26B343B4E0536F38A8C01387/datafile/','/u01/app/oracle/oradata/ora18c/pdb1/','+data/slnngk/C21CD091742C46B3E0536F38A8C09100/datafile/','/u01/app/oracle/oradata/ora18c/pdb2/','+data/slnngk/64A52F53A7693286E053CDA9E80AED76/datafile/','/u01/app/oracle/oradata/ora18c/pdbseed/','+DATA/SLNNGK/C346A9F364EC42C8E0536F38A8C026FA/DATAFILE/','/u01/app/oracle/oradata/ora18c/pdb4/'

在原来的基础上加上新增的pdb5的映射关系
SQL>alter system set db_file_name_convert='+DATA/slnngk/datafile/','/u01/app/oracle/oradata/ora18c/','+DATA/slnngk/tempfile/','/u01/app/oracle/oradata/ora18c/','+data/slnngk/C21CCC2F26B343B4E0536F38A8C01387/datafile/','/u01/app/oracle/oradata/ora18c/pdb1/','+data/slnngk/C21CD091742C46B3E0536F38A8C09100/datafile/','/u01/app/oracle/oradata/ora18c/pdb2/','+data/slnngk/64A52F53A7693286E053CDA9E80AED76/datafile/','/u01/app/oracle/oradata/ora18c/pdbseed/','+DATA/SLNNGK/C346A9F364EC42C8E0536F38A8C026FA/DATAFILE/','/u01/app/oracle/oradata/ora18c/pdb4/','+DATA/SLNNGK/C34A5522517E2082E0536F38A8C01CFA/DATAFILE/','/u01/app/oracle/oradata/ora18c/pdb5/' scope=spfile;

 

5.重启动从库

SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup
ORACLE instance started.

Total System Global Area 2466249080 bytes

Database opened.

6.从库应用日志

SQL> alter database recover managed standby database using current logfile disconnect from session;

Database altered.

SQL> show pdbs;

CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
2 PDB$SEED READ ONLY NO
3 PDB1 READ ONLY NO
