主库添加数据文件后，备库因为创建文件失败而停止数据同步。

 

1.查看主库环境的数据文件

SQL> select file#,status,name from v$datafile;

     FILE# STATUS  NAME
---------- ------- --------------------------------------------
         1 SYSTEM  +ABCE/test/datafile/system.293.930567941

        11 ONLINE  +ABCE/test/datafile/dtest.327.931996267

　

2.查看备库的数据文件

SQL> select file#,status,name from v$datafile;

     FILE# STATUS  NAME

修复方案

在备库执行以下操作

SQL> show parameter STANDBY_FILE_MANAGEMENT

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
standby_file_management              string      AUTO
SQL> show parameter db_file_name_convert 

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
db_file_name_convert                 string      +ABCE/test/DATAFILE/, /t01/app/oracle/oradata/teststby/datafile/, 
						 +ABCE/test/TEMPFILE/, /t01/app/oracle/oradata/teststby/tempfile/
SQL> alter system set standby_file_management=manual;

System altered.

SQL> alter database create datafile ‘/t01/app/oracle/testuct/11.2.0/dbhome_1/dbs/UNNAMED00008‘ as ‘/t01/app/oracle/oradata/teststby/datafile/dtest.295.981369995‘;

Database altered.

SQL> alter system set standby_file_management=auto;

　　

然后重启MRP

SQL> alter database recover managed standby database cancel;
alter database recover managed standby database cancel
*
ERROR at line 1:
ORA-16136: Managed Standby Recovery not active

SQL> alter database recover managed standby database disconnect from session;

　　

可以再次查看alert日志
