RMAN Backup problem

[hamster]

Hi,

We are facing strange issue for backup of one of the client using RMAN. The netbackup server is 5.1 hosted on solaris and the client is windows. There are 4 databases hosted on the client but out of these 4 databases backup of one of them has been failing. Below is the error:

Released channel: t2
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of backup command on t1 channel at 02/13/2011 09:28:04
ORA-19506: failed to create sequential file, name="epla_df_lev0_26916_1_742987657", parms=""
ORA-27028: skgfqcre: sbtbackup returned error
ORA-19511: Error received from media manager layer, error text:
VxBSAValidateFeatureId: Failed with error:
Server Status: cannot connect on socket


If the client isnt able to connect to Netbackup, then this should be the case for all the backups being taken from the client. But backup for other 3 databases is going on absolutely fine, only this one is failing.

Please advise what to look for and where to look for.

Many Thanks

Please check dbclient log on client for clues.

If the directory does not exist, create it under ...\veritas\netbackup\logs and retry the backup.

My guess right now is that it might be a timeout - default client connect and client read timeout on media server is 5 minutes. This is sometimes not enough for larger databases. Increasing both timeouts on the media server to 1800 (30 minutes) is normally sufficient for most databases.
