Creating Exit Point program

  • 1.  Creating Exit Point program

    Posted Tue August 24, 2021 03:14 PM
    Is anyone aware of a good site/reference for exit point example programs.  We have implemented PowerHA and recently found there are exit points which can be used to assist in starting/stopping applications that reside on the iASP.  The exit program I have written is not working and there doesn't appear to be an easy way to debug it.  I have looked at a few presentations from past IBM/Common conferences, but there isn't details that I can find.

    Hello Michael,

    We have this working for customers, the complete switch is automated with Exit Point Programs. We use this in combination with Advanced Job Scheduler (AJS) for stopping and starting the applications. Using AJS allows us, to monitor the progress of the switch by mail. AJS is able to mail it's activity, did a job run normal or abnormal. In the abnormal case AJS also has functionality to mail the joblog with error. The icing of the cake, is a history of when it was executed and how long it did ran. 

    The reason why we use AJS is because of it's     flexibility in maintenance. We never have to recompile a program when making changes. 

    If you wish, I can demo this. (For this however I need the customers approval) I do not expect that to be a problem. 

    Greetings Rudi

    Hi Michael,

    I am the product manager for the IBM PowerHA product at HelpSystems. The great news is that many PowerHA customers automate their switch process, including starting and stopping applications.

    Which exit points were you currently looking at for your automation?

    Check on your system. You may have a library QZRDPWRHA, and if you do, there will be source files in there. Example: QCLSRC.PWRDWNExit is a skeleton for the QIBM_QWC_PWRDWNSYS exit point processing program.

    Luck,
    Steve

    Steve,

     

    I did just uncover those hidden jewels of the skeleton programs.  It's too bad they never showed up with all of the ways I tried to search for them. 

     

    Thanks for the tip.

    Hi Steve & Michael

    do you know from where one can get the library - QZRDPWRHA?   because we don't have it on our OS - v7r4


    Thanks

    Dear Edward

    If you Google with "ibm i QZRDPWRHA", you will find that this library is part of a toolkit named Smart Assist developed by IBM Technology Service team that takes care of PowerHA for i and it is a chargeable product. You need to reach the team to buy the toolkit.

    I'm trying to locate a sample CRG exit program in CL. I have the one written in C but in our case we don't have the C compiler.

    Thanks

    Dear Edward

    Do you know of any colleague in your system who is already using RPG or COBOL compiler?  If so, it means that you have the product 5770-WDS IBM Rational Developer for i and it also delivers a C/C++ compiler.  It's just that you need to install WDS option of this C compiler and use it.

    Dear Satid

    Thanks for the clarification. I did not realise that the C compiler is included in the WDS products. I have installed and will use this.

    As regards QZRDPWRHA - I can work without it. I have developed most of the tools we need with CL. I requested this because I thought IBM included an exit routine in CL.  But now I can use the one written in C

    Regards

    Edward
