consistent with your finding on the semaphore.
Something I forgot to ask: which exact version of
9ir2 you running?
Logged on as SYSTEM, do a
SELECT * FROM V$VERSION
to find out.
I'll see what I can dig from Metaclick on semaphores
and Mandrake+Oracle to see if it is something to do
with the specific Linux release.
