We are running RMAN user directed backups and backing up oracle.  The
client is an E10K running solaris 2.8.  The netbackup master server is
running solaris 2.8.   I am seeing the following error:

 

11:12:51.348 [4683] <2> log_client_queued: empty-main bpsched is busy

 

 

This is during an RMAN test scenario when no other backups are running.
Any ideas as to why bpsched is busy with no other clients being backed
up?  Rman backups for the dev instance of oracle backup just fine from
another client.  We just hit the bottleneck when the prod instance is
backed up on the production oracle server.  The kernel parameters for
the master server are tuned to NetBackup recommendations.

 

Thanks,
