[suse-oracle] More Database 9.2 to 10.2 Upgrade Problems

Greg Wallace


Well, still more glitches with my conversion from 9.2 to 10.2. It seems
like as soon as I get one set of problems resolved I find something else.
Right now, I am have the following 2 problems (neither of which occurred
under 9.2) --

1) I have 2 user accounts, one called ORACLE and one called GREGW. I use
ORACLE only for installing and upgrading ORACLE. I do all of my actual
development work under GREGW. Under 9.2, I could start and stop the
database, listener, and apache (ISQLPLUS) from either id and if I switched
over to the other id I could still access everything. Under 10.2, that's
not the case. If I start Oracle under ORACLE, then I cannot access Oracle
under GREGW, and vice versa. In either case, if I start the database under
one of these ids, switch to the other id, and try to log in, I get the
following --

ORA-01034: ORACLE not available
ORA-27123: unable to attach to shared memory segment
Linux Error: 13: Permission denied

2) I am only able to start ISQLPLUS from the ORACLE account. If I try to
start it from GREGW, it gives me the same messages as under ORACLE, all
indicating that it started, but it is, indeed, not started (I go to the
ISQLPLUS port via a browser and there's nothing there). Maybe there's an
error log somewhere, but there were no dumps written into bdump or udump and
no messages in the alert file under bdump.

Any help greatly appreciated.
