Variants
TIBEMS_SESSION_TRANSACTED
transacted
TIBEMS_AUTO_ACKNOWLEDGE
In this mode, the session automatically acknowledges a message when message processing is finished—that is, when either of these calls returns successfully: synchronous receive calls (such as tibemsMsgConsumer_Receive) asynchronous listener callback (namely, tibemsMsgCallback)
TIBEMS_CLIENT_ACKNOWLEDGE
In this mode, the client program acknowledges receipt by calling tibemsMsg_Acknowledge. Each call acknowledges all messages received so far.
TIBEMS_DUPS_OK_ACKNOWLEDGE
As with TIBEMS_AUTO_ACKNOWLEDGE, 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.
TIBEMS_NO_ACKNOWLEDGE
In TIBEMS_NO_ACKNOWLEDGE mode, messages do not require acknowledgement (which reduces message overhead). The server never redelivers messages. This mode and behavior are proprietary extensions, specific to TIBCO EMS.
TIBEMS_EXPLICIT_CLIENT_ACKNOWLEDGE
As with TIBEMS_CLIENT_ACKNOWLEDGE, the client program acknowledges receipt by calling tibemsMsg_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.
TIBEMS_EXPLICIT_CLIENT_DUPS_OK_ACKNOWLEDGE
In this mode, the client program lazily acknowledges only the individual message, by calling tibemsMsg_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.
