Error description

  • Since migrating to WebSphere MQ v7.0.1.3 the enduser is
    experiencing connection failures for a Java application. The
    following error messages are logged in the WebSphere MQ
    error log, along with a FDC report.  Then enduser is attempting
    to perform data conversion from CCSID 1208 (Windows) to CCSID 37
    (iSeries).
    .
    WebSphere MQ Error logs:
    AMQ9208: Error on receive from host xx.xx.xx.xx.
    EXPLANATION:
    Cause . . . . . :   An error occurred receiving data from
    xx.xx.xx.xx over TCP/IP. This may be due to a communications
    failure.
    Recovery  . . . :   The return code from the TCP/IP read() call
    was 3426 (X'X'00000D62''). Record these values and tell the
    systems administrator.
    .
    AMQ6048: DBCS error
    EXPLANATION:
    Cause . . . . . :   WebSphere MQ is unable to convert string
    data due to a DBCS error. Conversion is from CCSID 1208 to
    CCSID 37.
    Recovery  . . . :   Check the WebSphere MQ Application
    Programming
    Reference Appendix and the appropriate National Language Support
    publications to see if the CCSIDs  are supported by your system.
    .
    AMQ9492: The TCP/IP responder program encountered an error.
    EXPLANATION:
    Cause . . . . . :   The responder program was started but
    detected

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    WMQ users utilizing pre V6 java clients attempting to connect
    to a V701 server
    
    Platforms affected:
     All Distributed (iSeries, all Unix and Windows)
    ****************************************************************
    PROBLEM SUMMARY:
    When a pre-V6 java client attempts to connect to a V701 server,
    WMQ is incorrectly negotiating options that are not available
    to that client. This is resulting in conversion errors such as
    AMQ6048.
    

Problem conclusion

  • WMQ server code has been modified to accommodate pre-V6 java
    clients so that the appropriate options are negotiated.
