I have a client using 10.2.0.4 64 bit on AIX.
After an upgrade from 9 to 10, his database went (after running for about 15
hours) into quiesce mode without anyone specifically performing such an
action. (Unfortunately, no more specific data available right now; only
thing he noticed in the alert log was a log writer switch on redo01.log when
this happened).
After a while, his db went unquiesce again. I searched docs, metalink,
Google but did not find a clue why a DB would do this all by itself.
A) Is this possible anyway?
B) What could cause this?

Thanks,

Shakespeare

Something like that should be recorded in the alert log. Posting the
relevant information from the alert log would certainly help people on
this group during the diagnostic process.

Hallo Shakespeare,

We have the same problem, last week we have upgraded to 10.2.0.4 on
AIX 5.2 64 bit.
And at the moment we have already 2 times a quiesce mode.
In the alert log is written:
Mon Aug 25 11:21:09 2008
Thread 1 advanced to log sequence 3080 (LGWR switch)
Current log# 3 seq# 3080 mem# 0: /oradata/xmcp/redo03.log
Current log# 3 seq# 3080 mem# 1: /oradata/xmcp/redo03b.log
Current log# 3 seq# 3080 mem# 2: /oradata/xmcp/redo03c.log
Mon Aug 25 11:44:11 2008
Database in quiesce mode

Database out of quiesce mode

Hello Louis,

this looks EXACTLY like our problem! We'll investigate this, and will report
here!

This is the part of the alert log:
