PropertyControl (MQLONG)

This field specifies what happens to properties of messages when the message is about to be sent to a V6 or prior queue manager (a queue manager that does not understand the concept of a property descriptor).

The value can be any of the following values:

MQPROP_COMPATIBILITY: If the message contains a property with a prefix of mcd., jms., usr., or mqext., all message properties are delivered to the application in an MQRFH2 header. Otherwise all properties of the message, except those properties contained in the message descriptor (or extension), are discarded and are no longer accessible to the application.; This value is the default value; it allows applications, which expect JMS-related properties to be in an MQRFH2 header in the message data, to continue to work unmodified.
MQPROP_NONE: All properties of the message, except those properties in the message descriptor (or extension), are removed from the message before the message is sent to the remote queue manager.
MQPROP_ALL: All properties of the message are included with the message when it is sent to the remote queue manager. The properties, except those properties in the message descriptor (or extension), are placed in one or more MQRFH2 headers in the message data.

This attribute is applicable to Sender, Server, Cluster Sender, and Cluster Receiver channels.
