Hi!
Yep it could very well be an crashing/stuck
archiver process problem. When instance is restarted by sysadmin, archiver is
started again and it archives online logs allowing further DML to be made and
redo to be generated.
Also, when users phone you next time, try to
tnsping your service, to see whether network and listener are ok.
Next thing is trying to log on as sysdba, these
connections can log on even when no more redo can't be generated. Then select
event from v$session_wait and see on what most events are waiting
for.
Tanel.

Checked the Following
1) Are there any error in the Alert.log file
2) Are the Database in Archivelog mode and
the Log_archive_start is not marked true and so it might be hanging after all
of the Redologs are been filled as Archiver is not running.
Thanks

Subject: 8.1.7 instance on Solaris
periodically goes sluggish, then
hangs... |
Hi,
rather vague, this one, I'm afraid, but we're stumped for
ideas.
We have an Oracle 8.1.7 instance on a Sun Solaris setup, which
we're currently testing prior to going live. Every so often - 2 or 3 times a
week - the users phone to say the application has stopped responding. They're
waiting several minutes with no response. We find we can usually fire up one
or two tuning apps, such as TOAD or Quest's Spotlight, but within a few
minutes, these also stop responding. By this time, even trying to fire up a
SQL*Plus session from my PC just hangs and hangs, without the login ever
completing. We always end up having to get the sysadmin to abort-shutdown
Oracle and then restart it. After which everything's fine - until the next
time.
I've checked the PROCESSES parameter, and this is set to 150 -
way above the maximum number of connections we've seen (around 40 or so).
Likewise SESSIONS and TRANSACTIONS parameters seem generously adequate. The
sysadmin says the server itself doesn't seem to be having any problems. He can
log in and run UNIX commands with no apparent performance problems.
Any
ideas at all would be very welcome!
