SessionTransacted
|
The
IsTransacted property has this value if the session uses transaction semantics.
|
Acknowledge Modes
|
|
AutoAcknowledge
|
In this mode, the session automatically acknowledges a message when message processing is finishedthat is, in either of these methods returns successfully:
|
ClientAcknowledge
|
In this mode, the client program acknowledges receipt by calling
Message.Acknowledge . Each call acknowledges all messages received so far.
|
DupsOkAcknowledge
|
As with
AutoAcknowledge , the session automatically acknowledges messages. However, it may do so lazily. Lazy means that the provider client library can delay transferring the acknowledgement to the server until a convenient time; meanwhile the server might redeliver the message. Lazy acknowledgement can reduce session overhead.
|
ExplicitClientAcknowledge
|
As with
ClientAcknowledge , the client program acknowledges receipt by calling Message.Acknowledge . However, each call acknowledges only the individual message. The client may acknowledge messages in any order.
This mode and behavior are proprietary extensions, specific to TIBCO EMS.
|
ExplicitClientDupsOkAcknowledge
|
In this mode, the client program lazily acknowledges only the individual message, by calling
Message.Acknowledge . The client may acknowledge messages in any order.
Lazy means that the provider client library can delay transferring the acknowledgement to the server until a convenient time; meanwhile the server might redeliver the message.
This mode and behavior are proprietary extensions, specific to TIBCO EMS.
|
NoAcknowledge
|
In this mode, messages do not require acknowledgement (which reduces message overhead). The server never redelivers messages.
This mode is available for topic sessions only.
This mode and behavior are proprietary extensions, specific to TIBCO EMS.
