I need some help with an NFS/Omniback issue I am having. We have an N-class running Oracle for an SAP app. That server also pushes out a couple of NFS clients to some app servers. The app servers are K460's and are the front end for SAP. The problem I am having is that the Omniback backup is hogging the disk so badly that I am getting RPC-lookup failures from the app servers. Here is what I want help on: Do any of you know how to tune down Omniback so that it runs at a lower level? I am fine with the backup taking longer if it frees up the disk a little. The disk is on Autoraid 12H. Any help would be greatly appreciated. Thanks!
We can take all the adventage from Omniback when the filesystems that we backups are mounted internaly, but when NFS file systems gets in play with the backup, this increase the network traffic considerably and RPC timeouts start playing.
You would increase the timeout value for your application server so that it could supports the storm of omni transfer.
