Thanks to to all of you who responded.

I received different answers. A couple of you advised me to keep the
crontab-entries in sync on both machines. This was no option, since both
machines should run different crontabs during normal operation. Another
option was to put the entries on disks that were within the
failover-services. No option for us too, but that's a political thing. We
don't want Unix-related stuff (like crontabs) on a non-Unix environment.
What I ended up doing: I wrote a script that syncs the crontab-entries on
the local disks of both systems, in two directories (one for each system).
When a failover occurs another script stops cron, reads in the right
crontab-file from the synced directory and starts cron again. Also, if you
put a service off-line the script clears the crontab-entries. In this way
the services are "linked" to the crontabs.

Thanks again!




Hi!

On my two AXP1200's I am running Digital Unix 4.0 E with two ASE
diskservices: test and production.
Both Alpha's have important cron-jobs stored locally. (For night-batches and
stuff like that). When the production-member dies, the diskservice will
failover to the test-member, but then the cron of my production-member does
not run anymore.
Do you have any ideas of how I could configure a failover for these
cron-jobs?



Greetings,
