Hi,

One of the Oracle databases shuts down once in every 2 or 3 days. It runs fine when it is issued the STARTUP command. When I had check the alert log prior to the startup I found these two lines

SMON offlining US=29
SMON offlining US=30


Not sure if it was shutdown for the above reason or someone had shutdown the db manually. Could you please help me in getting rid of this issue?

Note : I do not have the auditing enabled in the db.

How about the next few lines below these errors. I want to see the messages after these errors and when the instance crashed.

You have Automatic Undo Management turned on in your database which would make the Undo segements online/offline based on the load on the database. What I am trying to look for is some ORA error which may show up in Alert file at the time of crash. If not check in backgorund_dump_dest location if any backgorund process created a tracefile ?

Need more info to understand the reason for failure of instance.

Just information messages telling that some undo segments are useless and SMON offline them.

Nothing to worry about.

Regards
Michel

Hi,
someone had shutdown the db manually

Before shutdown your database are you restart your SERVER ( MACHINE) may be possible Oracle Database STARTUP TYPE IS MANUAL.
so you have to startup your database everytime when your restart your SERVER ( MACHINE)

check in services.msc << hit enter>>

or if startup is AUTO then please you have to post/upload your alert<sid>.log file.


Regards
Taj

What were you (or someone using your database) running at or around Fri May 11 11:22:05 2007?

You can check that trace file that the error referenced for more info.

Likely you are using Oracle without paying for it (which may or may not be ok, depending on situation), so Oracle support is not an option for you. If I'm wrong, call them up, and/or patch your database. It is an internal Oracle error.

If I'm right, then avoid doing whatever you were doing at 11:22 and just live without doing it. And consider paying for Oracle.
