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 summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 * * Release 1 Modification 0. * **************************************************************** * 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. 100Y CMQXRSRV
