RE: Dataguard - SRL unassigned on Standby

Hi  

I have found your answer ffrom a past post of Carel  

" Oracle documents that one needs at least the # of redo log groups on the
 primary + 1 on the standby, when standby redologs are used. I never saw  a logswitch happen to another standby redologfile than the one  previously used, so your observation is quite normal"  

it was in the list archive at freelist.org

It would seem that you have little to be concerned about    

Cheers

Subject: Dataguard - SRL unassigned on Standby  

Hi all,

Ora9205
AIX 5.3 We have set up DataGuard in the Max Performance mode. (SERVICE=DG_STY LGWR ASYNC=20480 OPTIONAL REOPEN=30 NOAFFIRM NET_TIMEOUT=60) The standby is about 2000 Kms away and connectivity is via a 4MBps line. Connectivity is NOT good.

The ORLs are being ported properly to the standby and the managed recovery is also taking place.

However, LGWR is reporting connection errors and we are getting these comments in the alert_PRIMARY.log:

Thu Nov 23 11:00:49 2006
LGWR: Completed archiving log 5 thread 1 sequence 6958 LGWR received timedout error from KSR
No action necessary. ARCH will attempt to transmit log file LGWR: Error 2 closing archivelog file 'DG_STY' Thu Nov 23 11:01:48 2006
Errors in file /ora/admin/primary/bdump/aaa_lgwr_2130034.trc: ORA-00002: Message 2 not found; product=RDBMS; facility=ORA LGWR: Error 2 disconnecting from destination LOG_ARCHIVE_DEST_2 standby host 'DG_STY'

The SECONDARY alert log does not report any errors BUT the Standby Redo Logs created there are still unassigned. They are NOT being used at all. ( The number and size of the SRLs match the ORL of the primary).

Have tried a metalinked and googled, but havnt been able to locate anything significant.

Any pointers ??

Thanks

Sanjay
