Information Value Data type Check box Default Selected Range
Cleared
Do not append RFH version 2 headers to messages sent to this destination.
Selected
Append RFH version 2 headers to messages sent to this destination.
Message body
New feature:Whether an application processes the RFH version 2 header of a WebSphere MQ message as part of the JMS message body.
Information Value Data type Drop-down list Default UNSPECIFIED Range
UNSPECIFIED
When sending messages, the WebSphere MQ messaging provider does or does not generate and include an RFH version 2 header, depending on the value of the Append RFH version 2 headers to messages sent to this destination property. When receiving messages, the WebSphere MQ messaging provider acts as if the value is set to JMS.
JMS
When sending messages, the WebSphere MQ messaging provider automatically generates an RFH version 2 header and includes it in the WebSphere MQ message. When receiving messages, the WebSphere MQ messaging provider sets the JMS message properties according to values in the RFH version 2 header (if these value are present); it does not present the RFH version 2 header as part of the JMS message body.
MQ
When sending messages, the WebSphere MQ messaging provider does not generate an RFH version 2 header. When receiving messages, the WebSphere MQ messaging provider presents the RFH version 2 header as part of the JMS message body.
ReplyTo destination style
New feature:Format of the JMSReplyTo field.
Information Value Data type Drop-down list Default DEFAULT Range
DEFAULT
The default value is equivalent to the information in the RFH version 2 header.
MQMD
Use the value supplied in the MQMD. This populates the reply to queue manager field with the value from the MQMD, equivalent to the default behaviour of WebSphere MQ Version 6.0.2.4 and 6.0.2.5.
RFH2
Use the value supplied in the RFH version 2 header. If the sending application set a JMSReplyTo value, then that value is used.
Asynchronously send messages to the queue manager
An option that enables the queue manager to acknowledge receipt of messages sent to it. Asynchronously sending messages to the queue manager is faster, but messages can be lost if the messaging infrastructure fails.

RFH2
Use the value supplied in the RFH version 2 header. If the sending application set a JMSReplyTo value, then that value is used. For more information about automatic client reconnection, see the WebSphere MQ information center.
Read ahead consumer close method
If Read ahead and cache non-persistent messages for consumers is set to Yes or As per queue definition this property is enabled. This property determines what happens to messages in the internal read ahead buffer when the message consumer is closed.
Information Value Data type Drop-down list Default Close method waits for all cached messages to be delivered Range
Wait for all cached messages to be delivered
All messages in the internal read ahead buffer are delivered to the application's message listener before returning.
Wait for the current message to be delivered
Only the current message listener invocation completes before returning, potentially leaving messages in the internal read ahead buffer, which are then discarded.
