I have following configurations for this database:

Path to log files = /u02/db2data/diniogr/WOGR/
Mirror log path (MIRRORLOGPATH) = /u03/db2data/diniogr/WOGR/NODE0000/
First active log file = S0000473.LOG
Log retain for recovery enabled (LOGRETAIN) = RECOVERY
User exit for logging enabled (USEREXIT) = OFF
First log archive method (LOGARCHMETH1) = TSM
Second log archive method (LOGARCHMETH2) = OFF
Options for logarchmeth2 (LOGARCHOPT2) =
Failover log archive path (FAILARCHPATH) = /u11/db2data/diniogr/DB/WOGR/failarch/

We have DB2 version 9 with fix pack 4.

Any one has face such problem.. any idea ??

Thanks in advance...
