In standby db, can't find sequence number of Last Applied Log.
Oct 18, 2012 2:44 PM
Standby database is behind the primary database for over 200 hours, to repaire this, we are using a incremental backup from primary database and a restored control file.
after starting up standby database, in Grid Control (OEM), can't find "last applied log" sequence number,
go to that standby, do
standby> select max(sequence#) from v$archived_log where applied='YES';
go to primary,
SQL> select max(sequence#) from v$archived_log where applied='YES';
then using OEM grid control, to Verify checks various standby database settings.
Connected to instance standby_server:standby
Starting alert log monitor...
Updating Data Guard link on database homepage...
Skipping verification of fast-start failover static services check.
Data Protection Settings:
Protection mode : Maximum Performance
Redo Transport Mode settings:
Checking standby redo log files.....OK
Checking Data Guard status
primary.com : Normal
standby.com : Normal
Checking inconsistent properties
Checking agent status
Checking applied log on standby........WARNING:
Timed out after 60 seconds waiting for log to be applied.
so how to fix this?
thanks you very much.
