Cluster resource dependencies

One of the most important steps when running IBM Workload Scheduler in the Windows® cluster environments is to verify that the dependencies have been set correctly.

To ensure IBM Workload Scheduler works correctly, the IBM Workload Scheduler cluster resource instance has to depend on the following resource types:
  • IP Address
  • Physical Disk
  • Network Name
as shown in the following example on Windows Server 2008
Figure 1. Resource Dependencies tab (Windows Server 2008)


You can decide to add more dependencies to ensure IBM Workload Scheduler launches jobs only after a given service is available. This happens when IBM Workload Scheduler schedules jobs that prerequisite other cluster aware applications. For example, to ensure the SQL job is launched only after the cluster aware relational database is available, add a dependency from the relational database cluster resource to the IBM Workload Scheduler cluster resource.
