Change username in DBA_USERS 2005-10-01 - By Radoulov, Dimitre
There should be a reason for Tom Kyte's answer :O)
<quote>
I'm surprised Tom let the one about updating the sys.user$ table slip by
without
any chiding. Wouldn't that be a strict no-no anyways?

Followup:
that would be strictly a no-no -- 100%

was thinking of changing the ownership column first.
But see, this works, with not a single error or warning in TRACE file.

Its a large dump, takes more than 5 hrs. so thinking to get it in "SHORT

Export problem was because of replicated objects.
can afford to have a corruption on my local test database.

Any good person will tell you to stop right now and do it the proper way
Fromuser / touser export is the only way of doing it, so fix your export
problems.

I remember one incident on LAZYDBAs , where a DBA did programming on
USER_ID and then required to change the USER_ID. He did it someway, but I am
unable to recollect.
There must be the way we can do. ( I think so).
