In CA Gen 8.5, user exits reside in the z/OS runtime DLLs. Customers migrating to CA Gen 8.5 must rebuild those user exits they have customized in prior release of Gen. The user exits are no longer linked into each generated application. All modified user exit must be rebuilt so they can be updated in their respective CA Gen 8.5 runtime DLL. JCL procedures that build the user exits and their specific DLLs are provided in the relevant CEHBSAMP datasets in members MKUEXITS, MK5EXITS (COBOL 5), MKUECTCP, and MKUEITCP respectively. The JCL to re-build the User Exits used by the C runtimes for Codepage translation reside in the member MKCRUN in the CEHBSAMP dataset. If the TIRXINFO user exit (included in MKCRUN) is modified, the resulting TIRXINFZ DLL must also be deployed.
Important! Care must be taken to ensure that the user exits used from previous releases are not inadvertently picked up from the SYSLIB concatenation through an auto-call. The CA Gen 8.5 user exits must be updated in their respective z/OS Runtime DLL.
For more information about User Exits and their associated JCL procedures, see the chapter 'Customizing and Installing User Exits', or the User Exits Guide.
