Error description

  • A WebSphere MQ v7 XA client application issues an MQCONN to a
    WebSphere MQ v6 queue manager. The MQCONN fails during a
    xa_open with reason code 2046, MQRC_OPTIONS_ERROR. This
    failure in the MSDTC process causes a UOW_ENLISTMENT_ERROR,
    which is MQRC = 2354. This also results in the xa_open call
    failing with a -3 (XAER_RMERR).

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users using WebSphere MQ V7 XA client application to connect to
    WebSphere MQ V6 queue managers.

    ****************************************************************
    PROBLEM SUMMARY:
    When an xa_open call issued by WebSphere MQ V7 client, it sets
    a connection option that is not supported on WebSphere MQ V6
    server. This causes the MQCONN call to fail with

    options while connecting to WebSphere MQ V6 queue manager.
