Activating the Subzero interface in MainView Batch Optimizer

This section explains how to activate the Subzero interface in MainView Batch Optimizer each time MainView Batch Optimizer starts.

To activate the Subzero interface at startup

  1. In the Subsystem commands member BCSCMDxx member for MainView Batch Optimizer, add the following command:
    mbos BSL SUBZERO ENABLE [IGNORE|WARN|FAIL] 
  2. (optional) Define the following additional keywords if you want to specify how MainView Batch Optimizer should react if a step fails to split: 
    • IGNORE (the default) allows the step to execute without issuing an informational message or user abend. 
    • WARN issues a warning message indicating that the target system is unavailable. 
    • FAIL issues an informational message explaining why the step failed to split.  

Note

You can also use the following keywords with the Subzero command:

  • DISABLE disables interfacing with Subzero.
  • STATUS shows whether interfacing with Subzero is enabled or disabled.

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.

Note

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 BSL POLICY ACTIVATE policyName
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: 
//*BSLCNTL DIRECT 
For more information about JTL statements, see the MainView Batch Optimizer Job Optimizer Reference Manual .
