ActiveVOS Server User’s Guide
The WS-Reliable Messaging policy assertion specifies that a partner link participates in an industry-standard protocol that supports guaranteed delivery of messages. To use this policy assertion in ActiveVOS, you must deploy your process to ActiveVOS Server that has Reliable Messaging configured and enabled.
The OASIS business standards consortium’s WS-Reliable Messaging standard provides a protocol for the guaranteed delivery of messages. ActiveVOS Server supports this standard, allowing BPEL processes to use the protocol to identify, track, and manage the reliable delivery of messages.
ActiveVOS Server’s implementation of reliable messaging is based on the following description.
After sending a message, ActiveVOS server waits for the amount of time set in the Acknowledgement Interval to get an acknowledgement message. If ActiveVOS times out and has not received an acknowledgement, then ActiveVOS waits for the amount of time set in the Base Retransmission Interval before resending. If the sequence has not completed within the amount of time set in the Inactivity Timeout, ActiveVOS server considers the sequence terminated.
The WS-Reliable Messaging attributes are as follows:
