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 HCL Workload Automation 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).
