Question:

I am getting an AKEB Abend code 683 at FFFF in module DFHSNTU for a newly created CICS regions, what causes this error?

 

Answer:

The CICS region is referred to as a multiple-user single address space system (MUSASS). A MUSASS can process multiple sign-ons and units of work on behalf of multiple users in a single address space. A region logonid is used to validate accesses by the CICS address space. A region logonid record must specify MUSASS for it to be considered a MUSASS. The MUSASS attribute allows multiple users to sign-on concurrently to the region and permits the CICS interface to perform resource access validations on behalf of multiple users.

The MUSASS privilege can be added to a logonid using the TSO ACF command processor as follows.

ACF
SET LID
CHANGE logonid MUSASS
