primary库新增数据文件后，standby库无法创建文件并终止数据同步

主库是RAC环境，使用asm存放数据文件，备库是操作系统本地文件系统存放数据文件。
在主库执行以下操作：

SQL> alter tablespace ysdv add datafile '+data' size 1024m autoextend on next 100m maxsize 10240m;

备库的alert日志报以下错误：

查看备库参数设置：

SQL> show parameter convert

------------------------------------ ----------- ------------------------------

------------------------------------ ----------- ------------------------------
standby_file_management              string      AUTO
SQL> 

原因是主备库的文件路径不一样，备库在自动转换文件名称时失败。

 

修改方案：
1.将stndby_file_management设置为manual

SQL> show parameter standby_file_management

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
standby_file_management              string      AUTO
SQL> alter system set standby_file_management='MANUAL';

2.找出unname的数据文件

SQL> select name from v$datafile;

NAME
--------------------------------------------------------------------------------
/d01/app/oracle/oradata/dvstby/datafile/system.293.930567941
/d01/app/oracle/oradata/dvstby/datafile/sysaux.294.930567941

/d01/app/oracle/oradata/dvstby/datafile/dv.327.931996267

10 rows selected.

3.重命名/重建数据文件，指定正确的名称

SQL> alter database create datafile '/d01/app/oracle/dvuct/11.2.0/dbhome_1/dbs/UNNAMED00007' as '/d01/app/oracle/oradata/dvstby/datafile/dv.328.950783567';

4.再次查看

SQL> select name from v$datafile;

NAME
--------------------------------------------------------------------------------
/d01/app/oracle/oradata/dvstby/datafile/system.293.930567941
/d01/app/oracle/oradata/dvstby/datafile/sysaux.294.930567941
/d01/app/oracle/oradata/dvstby/datafile/undotbs1.323.937148625
/d01/app/oracle/oradata/dvstby/datafile/users.296.930567941
/d01/app/oracle/oradata/dvstby/datafile/undotbs2.324.937148779
/d01/app/oracle/oradata/dvstby/datafile/dv.306.930571875
/d01/app/oracle/oradata/dvstby/datafile/dv.328.950783567

/d01/app/oracle/oradata/dvstby/datafile/dv.326.931996261
/d01/app/oracle/oradata/dvstby/datafile/dv.327.931996267

10 rows selected.

5.将stndby_file_management设置为auto

SQL> ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT=AUTO scope=both;

6.开启mrp

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

7.验证mrp已经启动

SQL> select process, status , sequence# from v$managed_standby;

PROCESS   STATUS        SEQUENCE#
