Manually switching the master
A manual switchover from the primary master domain managerto a backup master domain manager is invoked through the switchmgr command. The backup master domain manager becomes the current, active master connected to the IBM® Workload Scheduler database.
There are four main use case scenarios that can prompt the need for switch of the master to a backup:
- Planned outage
- The domain manager is replaced with its backup for planned maintenance work (for example, an upgrade of the operating system).
- Unplanned outage
- The domain manager is replaced with its backup because of an unexpected failure or malfunction.
- Short-term
- The domain manager is expected to return to service before the next new production period turnover (run of the JnextPlan job).
- Long-term
- The domain manager is not expected to return to service before the next new production period turnover (run of the JnextPlan job).
