ReplyToQMgr (MQCHAR48)

This is the name of the queue manager to which to send the reply message or report message. ReplyToQ is the local name of a queue that is defined on this queue manager.

If the ReplyToQMgr field is blank, the local queue manager looks up the ReplyToQ name in its queue definitions. If a local definition of a remote queue exists with this name, the ReplyToQMgr value in the transmitted message is replaced by the value of the RemoteQMgrName attribute from the definition of the remote queue, and this value is returned in the message descriptor when the receiving application issues an MQGET call for the message. If a local definition of a remote queue does not exist, the ReplyToQMgr that is transmitted with the message is the name of the local queue manager.

If the name is specified, it can contain trailing blanks; the first null character and characters following it are treated as blanks. Otherwise no check is made that the name satisfies the naming rules for queue managers, or that this name is known to the sending queue manager; this is also true for the name transmitted, if the ReplyToQMgr is replaced in the transmitted message. For more information about names, see the WebSphere MQ Application Programming Guide.

If a reply-to queue is not required, set the ReplyToQMgr field to blanks, or (in the C programming language) to the null string, or to one or more blanks followed by a null character; do not leave the field uninitialized.

For the MQGET call, the queue manager always returns the name padded with blanks to the length of the field.

This is an output field for the MQGET call, and an input field for the MQPUT and MQPUT1 calls. The length of this field is given by MQ_Q_MGR_NAME_LENGTH. The initial value of this field is the null string in C, and 48 blank characters in other programming languages.
