Home -> Community -> Mailing Lists -> Oracle-L -> RE: automatic undo 100% used
Paula,
I don't have the formula handy for calculating undo retention but a
google should provide it. Have you set your retention period to large
and retaining days/hours of undo info? The default is quite large.
Does the batch process perform a lot of uodates that require
a lot of old/new info to be retained in case of rollback?
The first time i set up the undo area I accepted the defaults
and consumed 6 Gig on a long running update.
Check you parameters in the initxx.ora file.
You can also create a new undo tablespace and assign it in the
initxx.ora.
Then offline drop the old one and you can then delete it from the os.

Have 3Gb allocated for undo retention, a few batch processes and
tablespace is showing 100% full. Is this normal behavior? I am used
to
old rollback segments where it would be and likely revolve around
poorly
written batch processes.
