11.1 IBM Tivoli Workload Scheduler

To manage the resources defined to DFSMSrmm, you need to run the inventory

management tasks, also known as

housekeeping periodically. DFSMSrmm

provides the EDGHSKP utility to help you perform inventory management. A job

scheduling product like IBM Tivoli Workload Scheduler for z/OS (which

incorporates Tivoli Operations Planning and Control (OPC)) will be helpful to run

these tasks.

IBM Tivoli Workload Scheduler for z/OS is a system management product that

functions as a batch job scheduler. You can configure the typical DFSMSrmm

batch job flow to IBM Tivoli Workload Scheduler for z/OS to run inventory

management jobs regularly. This provides the following benefits:

 Prevents more than one EDGHSKP job from running at the same time

 Avoids jobs failing because inventory management is already running

 Prevents EDGUTIL VERIFY jobs from running at the same time as an

inventory management jobs

 Handles the dependencies between jobs

The sample IBM Tivoli Workload Scheduler for z/OS stream included in the

DFSMSrmm SAMPLIB library proposes the following steps when running

inventory management. The name between ( ) is the sample member name
