Introduction:

With mainframe products, dumps and other diagnostic processes can sometimes create very large files that are difficult to transmit to CA Technologies support engineers. It has been a standard for many years to compress this data using the IBM TRSMAIN program.

These questions are related to the history of the AMATERSE program, which is now the recommended program to use.

Question: 

  1. For years technicians have been using TRSMAIN (from IBM) instead of AMATERSE. Where did AMATERSE come from and when was it introduced?
  2. Does one replace the other?
  3. TRSMAIN used to be a free program that was downloaded separately from IBM. Is AMTERSE the same way or is it now incorporated and documented in the newer z/OS releases?

Answer: 

  1. For years technicians have been using TRSMAIN (from IBM) instead of AMATERSE. Where did AMATERSE come from and when was it introduced? 
    Answer: AMATERSE replaced TRSMAIN in z/OS V1R9 (1.9). It was added to the Base Control Product (BCP) element of z/OS (part of the core functionality), and was rewritten to internal IBM coding standards. At that time it was renamed to AMATERSE. It was also available via PTFs UA36927 and UA36928 for APAR OA19194 with z/OS 1.7 and 1.8.
  2. Does one replace the other? 
    AnswerAs noted above, AMATERSE replaced TRSMAIN. It was shipped with an alias entry point for TRSMAIN, and when that program name is used, it will use the INFILE and OUTFILE DD statements instead of the standard SYSUT1 and SYSUT2 now in use with AMATERSE. This maintains full backward compatibility.
  3. TRSMAIN used to be a free program that was downloaded separately from IBM. Is AMTERSE the same way or is it now incorporated and documented in the newer z/OS releases? 
    AnswerSince it is incorporated as part of the BCP element of z/OS 1.9 and above, there is no special need to download and install AMATERSE. It is readily available and is a recommended method to transmit dumps and other diagnostic materials to IBM and other vendors.
