We have an Active/Standby pair of AIX 5.3 Unix servers. Business requirement dictates keeping a list of components synchronized between them e.g. Oracle RDBMS using Data Guard and certain OS file & folders which includes /var/spool/cron/crontabs.
Problem with keeping CRON related files sync'd is that they will also run on Standby which we do not want. What are some methods for preventing the jobs from executing on Standby?
My thoughts so far is stopping the "CRON" process (if that's the exact Unix process name for it) but unsure if there's a chance it might get started by a monitor process.
