AK - Go to Google and search on oracle alert log monitor script. This will give you an array to select from.

RE: perl/shell script for alert log
If you use Connor's script you can modify it to send you the entire chunk of
file it is currently checking in the body of the email. Ideally you are
checking at a frequent interval so the time of the alert is usually about
the same time you get the error message.
One enhancement I suggest to every script is to configure the a SERVERERROR
trigger to throw certain errors out to the alert log. ORA-1555 is one that
will show up at the session level but not at the database level. Out of
TEMP space is another that is frequent at the session level but not the
database level. This way you know who is causing some important errors.
Overtime I find more and more session errors that are really critical
database errors. Try DDL on a table with an unusable index. Pretty big
deal on most production databases but this is a session error and would not
typically show up in the alert log. The risk of course is some huge loop
throwing 1000's of lines into the alert log. I would suggest a governor of
some sort in your servererror trigger.

RE: perl/shell script for alert log
Welcome back Ethan!
An alternative is using the following lines in init.ora:
event=1555 trace name errorstack level 3
event=4031 trace name errorstack level 3
event=1652 trace name processstate level 10
This catches the dreaded 01555, out of TEMP, and shared pool allocation
errors *along* with the SQL/Stack from the offending process (and thus time
of occurrence).
And keep *all* the event lines together ;-)

Hey, awesome tip! Been here, lurking. Does that generate a trace file with more than just session id and serial# in it? Nice thing about SERVERERROR is I can get machinename, username, osuser etc and stuff it in alert log so I see who caused the error when I get the email, but your way is clearly easier to implement. - Ethan -Original Message- Sent: Wednesday, August 27, 2003 3:49 PM To: Multiple recipients of list ORACLE-L Welcome back Ethan!

RE: perl/shell script for alert log
Yeah, I log those. Some of the db's I support run with very small redo logs and I can't change. They get those quite frequently at times so I pretty much ignore them. My script also reacts (log,email,page, or run some script) in the event of startups, shutdowns and alter database structure. It also sends everything through a filter of known patterns and anything that is not recognized falls out. I call this the paranoid switch -p. One best practice I recommend is to automate control file backups anytime a ALTER TABLESPACE, ALTER DATABASE etc...is in the alert log. -Original Message- Sent: Wednesday, August 27, 2003 4:55 PM To: Multiple recipients of list ORACLE-L Hi!
