DBA Chirag


This is the problem with the Oracle backgroud processes.

Talked to Oracle. I have to find which iTAR it was, but as per
discussion and results he shown to me, clearly telling that this was
the PMON Process.

When user logs off, All the processes completed properly.. i.e.
Closing of cursors n all. but finally while cleaning up the resources
it was giving error.

Oracle told that, nothing to worry, yr data and Database both are up
and running as well as nothing has mishapped with memory structure.

So Oracle Technical Expert has asked to IGNORE THIS ERROR. I am still
keeping watch and asked him to take this to further lever if the same
error we encounter again.

Thank you,
