Good afternoon,
Many of our database servers are running Oracle Linux Kernel Release 5
Update 4. We have been patching these servers and discovered our RMAN
performance (to NFS shares) has suddenly dropped ( from 100+ mb/s to 10
mb/s). It took us quite some time to figure out that it is actually the OS
patch that is causing the issue. We even applied the latest patch (Kernel
Release 6 Update 2), but we are still running into the same issues.
Has anybody else encountered this issue? We have not made any changes to
the mount options for our shares. We haven't made any changes to the NFS
server itself. We ran a backup to local disk, moved underlying storage for
NFS, etc. We finally determined that it is caused by our OS patch.
Any help would be appreciated.
Thank you,
Jay Hostetter
