Database uptime monitoring by either snmp or active monitor script anyone?

Question

Hi,
Has anyone previously setup any type of active monitoring script through whats up gold or an snmp informant type of monitoring script to advise when a database is down or specific process is down?
An example would be like ORACLE_PKG1, and the process is named ora_smon_hrprd88.
This is what the HP-UX “ps” shows:
tpadb01:/# ps -ef | grep -i ora_smon
oracle 13207 1 0 Jan 1 ? 0:29 ora_smon_epprd88
oracle 13281 1 0 Jan 1 ? 1:31 ora_smon_hrprd88
oracle 13635 1 0 Jan 1 ? 1:03 ora_smon_fsprd84
oracle 3620 1 0 Jan 2 ? 0:18 ora_smon_mtprd04
oracle 14586 1 0 Jan 1 ? 0:23 ora_smon_mtprd05
oracle 15223 1 0 Jan 1 ? 0:26 ora_smon_inprd88
oracle 15879 1 0 Jan 1 ? 0:25 ora_smon_epsal88
oracle 16769 1 0 Jan 1 ? 0:52 ora_smon_hrsal88
root 17976 22609 0 10:46:39 ttyp2 0:00 grep -i ora_smon
tpadb01:/#
Not sure if the extra info helps, but you never know. We can set it up to send us database up alerts, but the problem I have is when the listener service is down I can't get my script to finish no matter how I change the values of my script around. I can provide my script if that would help as well. If someone has already done this and is willing to share great!

I would suggest you install OEM Grid Control to monitor your databases. For basic monitoring function it's free. OEM GC works great, it's a little overweight though. It's also use SNMP.
Or you can choose any third party tool like

or some commercial one like Quest Software.
