Modifying the IBM-supplied governor exit routine or writing your own

If you decide to govern resources other than the number of rows returned from the database or the processor time expired, you need to modify the IBM-supplied governor exit routine or write your own by doing the following:

1. Establish addressability to the exit routine for the points at which QMF calls the routine. How and when QMF calls the governor exit routine explains this step.
2. Pass resource control information to the governor exit routine and store this information. Passing resource control information to the governor exit explains this step.
3. Establish addressability to the QMF cancellation service to cancel activities. Canceling user activity explains this step.
4. Establish addressability to the QMF message service to provide messages for activities that have been canceled. Providing messages for canceled activities explains this step.

See the following sections for OS/390, VM, and VSE for additional steps for those particular platforms.
