How to configure correct codepage for Java proxy and TCPIP middleware for WAS 9 on Red Hat Linux

  • 1.  How to configure correct codepage for Java proxy and TCPIP middleware for WAS 9 on Red Hat Linux

    Posted 10-17-2017 11:12 AM

    There are a number of transaction dumps in the CICS logs for E3AV . The abends started  occurring last Wednesday (10/11).

    The IEFT abend indicates a problem with (e.g. wrong) code page definition.

    If I had to guess I would say that these abends are coming from the Linux box. Probably the Linux machine needs a different code page for translation that the Windows machines.

    Douglas,

    I wonder if you can open a problem with CA-Gen support for this problem.

     

    1. Win-10 PC with WAS9 connecting to CICSS010 port 3073               OK
    2. WinServer 2008 with WAS7 connecting to CICSS010 port 3073     OK
    3. RedHat Linux server with WAS9 connecting to CICSS010 port 3073            Fails

     

    We have tried swapping the JAR files between the non-working and working setups, and those make no difference.

    This is interesting:

    [Function: TCPIPConnection::readData]Error attempting to read data (Connection reset)

     

    It seems like there is a problem reading the data, but is it a problem reading the data in CICS, or ??

    Hi Douglas,

    Yes the IEFT abend is an indication that the CICS server does not have the required codepage pair included for the client codepage being sent.

    If you already have java proxy running successfully from a Windows machine what codepage pair did you previously add to CICS? Was it 1201<->37?

    It is possible that the java proxy on different platforms will send different codepages because of the way java runs on the different OS's. The best way to check what is being sent is to enable "CMIDEBUG=ON SYSTEM" in the java proxy commcfg.properties file. The WAS SystemOut.log should then contain the CMIDEBUG output including the Common Format Buffer which will contain the codepage being used.

    Here is a relevant KB article which also includes the alternative option to force a specific client codepage by editing the java proxy user exit CFBDynamicMessageEncodingExit.java:

    Why does my Web Application fail with an IEFT abend on CICS server? 

     

    Hope that helps

     

    Regards,
