Activating a job policy in Job Optimizer

The job policy becomes active when you start the MainView Batch Optimizer Subsystem on the images in the BatchPlex.

Your site's initial job policy was created during the MainView Batch Optimizer customization process. The name of the job policy is defined within the BatchPlex definition. For a new job policy, you must activate the policy on each MVS image in the BatchPlex.


If you created a new policy, or edited an existing policy to include the new DIRECT keyword, you cannot activate the policy on a previous maintenance level of MainView Batch Optimizer.

To activate a job policy

Enter the following command:
mbos is the subsystem ID of the MainView Batch Optimizer Subsystem that is active on the MVS image.
policyName is the name of an existing job policy definition in the control data set. Omitting policyName reactivates the currently active job policy.  

Adding the DIRECT JTL statement

Use the following procedure to add the DIRECT JTL statement.

Add the following JTL statement immediately after a job in the MainView Batch Optimizer JCL: 
For more information about JTL statements, see the MainView Batch Optimizer Job Optimizer Reference Manual .
