Hello,
Very strange problem with CommVault RMAN (archive) backups.
Sometimes a RMAN archivelog backup job stays “running” forever/hangs.
It's not related to a specific Oracle instance, the problem occurs with all instances.
At random, sometimes the jobs run and finish OK in a couple of minutes and sometimes stay running forever.
Host (Windows2016) memory and CPU performance is ok.
ClOragent.log logging stops at : OraObject::GetOraMode() - oraMode = READ WRITE
So hangup occurs before the RMAN script is called.
No entry in the database alert.log at that timestamp, just skipped.
Looks like communication with the CIOragent.exe process is lost, although it is still running on te server…
Hope you have an idea how to solve this problem...
