RFS[22349]: Database mount ID mismatch

今天检查数据库发现一套主库上面报大量RFS[22349]: Database mount ID mismatch之类的错误

[oracle@hisdb2 trace]$ tail -f alert_hisdb2.log 
LNS: Standby redo logfile selected for thread 2 sequence 133319 for destination LOG_ARCHIVE_DEST_2

RFS[27082]: Database mount ID mismatch [0x7afb8c50:0x70b2cf7b] (2063305808:1890766715)

这种错误表示rfs进程在传输的时候检测到database mount id不匹配(也就是认为这个库不是主库该传输或者接受日志的),出现类似这样的错误,大概率是由于这个dg成员(主库和备库)中应该有不匹配的库,回想这个库近期的操作,突然想到对这个主库在虚拟化平台的备库做了一次克隆,然后吧克隆库激活作为测试库的操作.基于此种情况,先判断该库是否和上次克隆的库之间创建有会话连接

--主库
[oracle@hisdb2 trace]$ netstat -natp|grep 192.168.106.63
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)

--克隆库
[oracle@HIS_DG ~]$ netstat -atpn|grep 192.168.115.12
(Not all processes could be identified, non-owned process info

两个库之间确实存在会话,检查克隆库相关的dg配置

该库的dg配置没有清除,当该库变为主库时,log_archive_dest_2刚好指向主库,从而使得主库上出现了类似RFS[22349]: Database mount ID mismatch的错误.处理方法是清除掉克隆库上面dg备库相关配置

SQL> alter system set log_archive_dest_2='';

System altered.

SQL> alter system set fal_server='';

System altered.

主库日志中未再出现类似错误

ORA-10485: Real-Time Query cannot be enabled while applying migration redo.

对于数据库打psu和jvm patch之后,dg备库同步会出现类似ORA-10485: Real-Time Query cannot be enabled while applying migration redo.异常

这种情况,是由于数据库在upgrade模式下产生日志无法正常被adg实时应用,我一般是临时rman应用备库日志解决,官方解决方案:MRP process getting terminated with error ORA-10485 (Doc ID 1618485.1)

11g CASE

---------

1> Stop DG broker (if used)
   i.e., on primary and standby

SQL> alter system set dg_broker_start = false scope = both sid = '*' ;
2> Stop managed recovery in the standby, shutdown the standby and startup mount.
    start managed recovery without real time apply.

SQL> alter database recover managed standby database disconnect ;
3> Wait until all the redo is applied to the standby and the standby is in sync.
     Do a couple of log switches on the primary, all instances if RAC, and let them apply to the standby.

4> Shutdown the standby and startup mount
   start managed recovery with real time apply.

SQL> alter database recover managed standby database using current logfile disconnect ; 
5> Restart broker(if used).

on primary and standby

SQL> alter system set dg_broker_start = true scope = both sid = '*' ;
 

12c CASE

----------

In 12c and later, start Archived log apply using below command with ARCHIVED LOGFILE option:

SQL> alter database recover managed standby database using archived logfile disconnect;
Wait until all the redo is applied to the standby and the standby is in sync. 
  Do a couple of log switches on the primary, all instances if RAC, and let them apply to the standby.

To stop Redo Apply, Issue the following SQL statement:
SQL>  alter database recover managed standby database cancel; 

start managed recovery with real time apply, Issue the following SQL statement
