    MVAO CSM and compiled Rexx

    Feli Brachthaeuser

      Hello,

       

      CSM requires to run compiled rexx. if one doesn't have the Compiler, job BBSAMP(BBREXALT) needs to be run.

      The Comment in the job states:

      NOTE: THIS JOB is NOT NECESSARY IF RUNNING Z/OS 1.9 OR LATER

      As we run z/OS 2.3 I wonder what to do.

      Any idea?

          Prior to z/OS 1.9, TSO required you either buy a special component or install the free code to run compiled EXECs.  IBM gave us permission to package the free copy with our libraries and give instructions on running it in STEPLIB of your PAS to allow you to run compiled EXECs.  But as of z/OS 1.9, you no longer have to do anything.  TSO provides the free version automatically.  So you don't have to do anything now.

           

          If you run into problems scheduling compiled EXECs in MainView AutoOPERATOR, please open a Case to BMC Support and we will assist you.

            By the way, we have found that running with compiled EXECs does not provide performance improvements.  However, doing a compile of your REXX EXECs after you make changes will flag any syntax errors that you might have missed. 

             

            If you are looking for performance improvements you should implement VLF.  This will give you the best improvement as VLF eliminates the need for TSO to read from DASD.

              Hi Jo,

              Thanks for your answer!

              Then we need to set the documentation straight.

              An entry in the CSM documenation still states this requirement.

               

              take care,

              Feli

                Hi Jo,

                I checked our MVAO STC in one specific environment.

                we start it SUB=MSTR.

                we were getting messages AA3001W and IEF196I.

                After executing BBREXALT and adding the modules to a APF authorized steplib, the Messages disapeared.

                What shall I do?

                Thnaks for your advise,

                Feli
