PI38143: MQRC=2046 (MQRC_OPTIONS_ERROR) RECEIVED WHEN CLIENT SENDS A MQCONN REQUEST WITH FAPMQCNO.VERSION AND MQCNO_RECONNECT_Q_MGR

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• MQRC=2046 (MQRC_OPTIONS_ERROR) is received when client sends a
  MQCONN request with FapMQCNO.Version and MQCNO_RECONNECT_Q_MGR
  is set in the Options field.  This results in the CHIN building
  a MQCNO with Version set to 1, and with the
  MQCNO_RECONNECT_Q_MGR Options bit set, which is invalid (it
  should build an MQCNO with Version set to 5, as it does when
  FapMQCNO.Version is set to 1).

  * PROBLEM DESCRIPTION: When a V750 Java client connects to a   *
  *                      V710 server on z/OS, with               *
  *                      MQCNO_RECONNECT_Q_MGR specified, the    *
  *                      client may get MQRC 2046,               *
  *                      MQRC_OPTIONS_ERROR.                     *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When the Java client sends the flow for connecting to the queue
  manager with MQCNO_RECONNECT_Q_MGR set, under certain
  circumstances it will send a FapMQCNO.Version value of 2.
  This value is not supported in MQ V710, causing the server to
  create a MQCNO structure with version set to 1. This version of
  the MQCNO structure does not support the MQCNO_RECONNECT_Q_MGR
  option, causing return code MQRC 2046, MQRC_OPTIONS_ERROR.
  

Problem conclusion

• The code in the server was changed to tolerate the incorrect
  FapMQCNO version value sent by the Java client by creating the
  internal MQCNO structure with the correct version.
