how to troubleshoot enq: WL - contention?
Date: Thu, 30 Oct 2008 09:44:55 -0400
We have been facing issues with our rman backups in cluster & in non-cluster envoronments due to this "enq: WL - contention". The rman backup just hangs at this point. Generally this is happening when we execute some command like "alter system archive log current". This is a recommended command to execute as part of backup procedure. Can any one please guide me to some resource where i can find more information about this.
