There are two approaches to this solution. They depend on your operating
system.
- Oracle supplies a tool called Oracle Enterprise Manager (OEM) with the
later releases of the database. Part of OEM is the Intelligent Agent. This
agent sits on the database server and reports events and problems back to the
controlling console (a pc). The console can then (depending on the event)
notify the DBA through email or paging. The problem is that you have to have
a version of Oracle installed on your database server that has the
intelligent agent. I think all versions after 7.1 have it, but it's not the
easiest thing to configure on Unix servers. If your server is NT it should be
a snap. I've done it on both Unix and NT and when it works it's pretty good.
The biggest problem is that it only sends messages to one person.
- If your database server is Unix then you can write simple shell scripts to
monitor the database processes at regular intervals and send an email or page
when they go down. You could, for example, have a program that checks for the
background processes every 10 minutes (ps -ef|grep smon) to determine if the
database is up. If you have NT you may be able to write a script to see if the
Oracle service is running by OEM with intelligent agent is the way to go.
Besides, it's free with your distribution.
Hope this helps.
