Verifying configuration and starting a region for non-Language Environment IMS MPPs

Before you debug an IMS MPP that does not run in Language Environment®, do the following steps:

1. Consult with your system administrator and verify that your system has been configured to debug IMS programs that do not run in Language Environment. See the IBM® z/OS® Debugger Customization Guide for instructions on how to include the APPLFE=EQANIAFE parameter string in the JCL that starts a region and EQANISET.
2. Start an IMS message processing region (MPR) that runs the EQANIAFE application front-end routine whenever a message processing program (MPP) is scheduled.

After you complete these steps, choose a debugging interface as described in Choosing an interface and gathering information for non-Language Environment IMS MPPs.
