Home -> Community -> Mailing Lists -> Oracle-L -> RE: Diagnose Slow System
I apologize if I missed the final post. Did you discovered the cause of the problem?

We've been fighting problems for several days. I've sort of overwhelmed
myself with data, but I don't know what any of it means.
Solaris 2.6, Oracle 8.0.5, MTS
Users complain of extreme slowness. No errors in alert, no trace files
generated.
Database is bounced every day. I capture wait statistics each day before
the database goes down. The statistics from v$system_event for enqueue
waits has gone up considerably since the problems started last Wednesday.
But when I look at v$lock (I'm using Steve Adams' enqueue_locks.sql
scripts), nothing pops up.
Any ideas where I should start looking? I would appreciate any help.
(I really believe this is a connectivity (networking) issue, but don't know
how to confirm this)
Thanks!
