User Exit LANSA Security Check

A user-defined program can manipulate the processing of the LANSA access check for an object and can return two parameters that will influence further processing. The User Exit Return Code parameter will determine whether to continue with the LANSA access check for an object (DC@P8001) processing or not.

If the user-defined program parameter User Exit Return Code returns a value of:

The valid values for Return Code are N or Y

If the user exit returns a Return Code value that is not Y or N, the LANSA access check for an object (DC@P8001) routine will ignore it and process as for User Exit Return Code value C.

If the Partition ID is required, it can be derived from DC@IDS parameter position 910 - 912.

The LANSA Security Check programs will pass these parameters to the user exit program:
