DFHUS0002 0304 in DFHUSAD when signing onto CICS TS 5.1 and using CA ACF2

Question & Answer

Question

Why would I receive message DFHUS0002 A severe error (code X'0304') has occurred in module DFHUSAD when trying to sign-on to CICS Transaction Server for z/OS (CICS TS) V5.1? I am using CA ACF2 from CA Technologies as my security manager.

Answer

Apply CA ACF2 fix number TR73740. Contact CA Technologies if you need additional assistance.

The x'0304' translates to USAD_INVALID_FORMAT. The trace, within the CICS dump produced, will show DFHUSAD is called for CHANGE_MODE but the parmlist passed to DFHUSAD has a bad USAD_FORMAT_NO. DFHUSAD expects a format number of x'BF'. The format number resides at x'04' into the parmlist. Below is an example trace entry and a portion of the parmlist (data area 1). Offset x'04' contains x'00000003' which is an invalid USAD format number.

The RET value will point to the caller of DFHUSAD that passed the bad parmlist. In this example it was CA ACF2.
