Modify cluster script without cmapplyconf ?

Juan Manuel López — Tue, 14 Jan 2003 13:08:46 GMT

I have got on my cluster config a script to start and stop the oracle databases every time the package go up or go down.
I have to modify the content.
The cuestion is : May I do this modification without execute cmapplyconf ? The modification is only inside the script.

Thanks.

Juanma.

If you are only changing the script that starts and stops your package, the answer to your question would be no. I would recommend bringing down your package first, make your chagne to your script and try it out after. I would also recommend, trying to switch your package to all your other nodes. cmapplyconf is for when you change something specifically to the cluster itself, like a new node in the cluster, or a new VG in the cluster.

Hope it helps

Hi,

As long as you do not modify the cluster or package configurations files, you don't need to use cmapplyconf. Don't forget to copy the modification on all the cluster nodes.

Sorry but if i understand well it's really not necessary the package shutdown to change the start and stop script. You should change the script and redistribute it to the other nodes. If you should change the package then it's an other matter...

I recently made a similar change. Modifying the customer defined stop/start commands themselves does not require the use of cmapply conf.

Once the changes are made, you will need to make sure that you copy your new file to any other servers in the cluster.

I don't believe that the changes are actively used until the next time that you start up your cluster, so you need to arrange to do that at a convenient time.

Adding to the other responses:

Make sure you *test* your modifications. Many times we see customer's packages failing to switch/(re-)start at a failover. Not good.
