Home -> Community -> Mailing Lists -> Oracle-L -> RE: Monitoring database thru cluster
We monitored the database via the cluster. Same hardware.
Its silly to have high availability software and not use it.
I realize that its mostly likely monitoring the disks.
If the database comes back up great, the users can start using
it and I can do my research as to why it crashed. If it does
not come back up due to a serious problem no loss in trying.
The package is just going to sit there and wait.

Forwading an email from a fellow DBA, for your assistance.
hi,
I have a situation over here. Here the environment:
We have a database on hp cluster and the cluster package is not monitoring
the database. Their contention is that if the database goes down due to any
reason the dba should take a look before starting it up. A valid point. But
there are instances when, if the database goes down all u need is to
restart
the database. On hp systems I have seen a peculiar problem when we have a
shutdown immediate for backup, the sga is not released. So you might have
to
give an ipcrm command or if that does not work reboot. Now in this case all
we have to do is switch over the package to the failover server and the
database is up without any problem and then we can reboot the primary box
with no downtime.
Now my question is:
Is it a good pratice to monitor the database processes thru the cluster?
Is there any other scenarios where the database might be down and all that
was reqd was a simple restart or reboot?
Regards
