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).
