how to check the availability of a SCS-Instance

[Former Member]

Hi.

We want to use HP serviceguard for our HA solution - but we do not want to pay so much money for the SAP serviceguard extensions. So we do it ourselves...

My question: how to check the availability of the SCS-Instance on regular basis on os level?

- is it enough to check the enqueue and message server process? I don't think so 🐵

- is it enough to check the latest entry of this file?

/usr/sap/<SID>/SCS<SYSNR>/work/available.log

some typical entry of this file looks like these:

Unavailable 30.04.2009 17:03:07 - 04.05.2009 11:32:33

Available 04.05.2009 11:33:33 - 05.05.2009 17:33:05

Available 05.05.2009 17:35:36 - 05.05.2009 17:35:36

Available 05.05.2009 17:37:51 - 06.05.2009 08:49:11

Other ideas?

Thanks for your help!

i want to run a script on os level that checks the state and forward it to the serviceguard. i do not know how this could work with jcmon...

Hi,

what type of script you want to run at OS level, u can check the status in MMC itself if you are using windows or u can check the status in index.html informaiton page or u can use JCMON at OS level to check the status.

In that case you can check the processes at OS level and grab the PID.

For example ps -ef | grep command
