Clustering - Initate the process on FailOver

[baskerk]

Hi,

I'm running a batch process on Windows Clustered Environment. During the batch process, if Node 1 fails, is it possible to initiate the same batch process in Node 2. Batch process will take care of resuming from the point it failed.

Should we need to do anything or will the clustering take care of this.

Thanks,
Basker

Is the batch process defined as a resource in a cluster group?

If YES, then the cluster service should start it up again on the other node and the process can do its thing of finding where it left off and continuing.

If NO, then I would expect it to fail and not automatically restart. You would have to restart it manually.

OR, if the process is running on a box outside of the cluster, write code into the process (script, batch file, VB, whatever) that can handle the unavailability of its required resources (fileshare or whatever managed by the cluster service) for the period of time that it takes the other node to take over and make the required resources available again, i.e. some timeout value. In that case the process doesn't fail; it just waits for resources to come back.
