How ESM exit programs access CICS-related information

When CICS® invokes the ESM, it passes information about the current CICS environment, for use by an ESM exit program, in an installation data parameter list. How your exit programs access the installation data parameter list depends on whether or not your ESM is RACF®.

This topic contains Product-sensitive Programming Interface and Associated Guidance Information.

If you use an ESM exit program that issues a RACROUTE REQUEST=AUTH and the exit is running because of a security request from CICS, you must ensure that any CLASS which is referenced is listed in the RACLIST.
