备库的日志:

RFS[5]: Possible network disconnect with primary database

Mon Aug 26 20:51:48 2013

从上面的日志看出,主库直接关闭,而不是切换日志归档,并且传输给备库

解决方法:

Manually grant 'rwx'-Privileges for the Primary and/or Standby Database to the Grid Infrastructure User using crsctl (assuming the the Grid Infrastructure User is called 'grid'):

% crsctl modify resource ora.prim.db -attr

"ACL='owner:grid:rwx,pgrp:dba:rwx,other::r--,user:oracle:rwx'" -f -i

% crsctl modify resource ora.stby.db -attr

"ACL='owner:grid:rwx,pgrp:dba:rwx,other::r--,user:oracle:rwx'" -f -i

This is not a Problem in 11.2.0.2 anymore, too as Part of the Fix for

Internal Bug 9705202: [11202-LNX64-100428]DB STAT KEEP INTERMEDIATE AFTER SIHA INSTALLATION

通执行

crsctl modify resource ora.rac.db -attr "ACL='owner:grid:rwx,pgrp:oinstall:rwx,other::r--,user:oracle:rwx'" -f -i

并且重启数据库后切换成功,但是还是有点点小问题。

edit database rac set property StaticConnectIdentifier = '(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=rac1)(PORT=1522))(CONNECT_DATA=(SERVICE_NAME=RAC_DGMGRL)(INSTANCE_NAME=rac)(SERVER=DEDICATED)))'
