Limiting Transaction Access to User IDs

The RACF APPL class controls which user IDs allocate conversations to a particular system.

Example:

• RDEFINE APPL IMSLU VACC(NONE)
• PERMIT IMSLU CLASS(APPL) ID(IMSUSER) ACCESS(READ) allows user ID (IMSUSER) to access system (IMSLU). IMSUSER must also have a RACF profile that limits which transactions this user can access.
