Forgive me if this is sound's ignorant but my DBA has not assured me.
We have been on oracle 9.i for over 6 months and we have now switched
to have the rollback space automanaged by Oracle. The question comes
up How much to set the undo retention. My understanding is that Oracle
when mananging undo space will keep the results of queries for the
amount of time (in secs) of the undo_retention. In our shop we do
thousands of transactions daily, most all commit at intervals. This
used to release rollback space. We do have the billing processes which
work for sometimes 2 days as a SINGLE transaction. In order to cover
for the large bill process we need to set the undo retention high --
its currently set at 48 hours. But does this mean that all of our
other transactions, inserts, deletes etc be held for 48 hours? Would
appreciate it if someone could shed some light on this
Thanks JonL
