Using Parallel Processing

To implement parallel processing, on the subscribing system associate the message on the inbound service operation with an unordered queue. If the message is currently assigned to an ordered queue, assign it to a unordered queue.

In order to realize any performance gain from parallel processing, multiple subscription handlers must be set up for the subscription node to process messages on the unordered queue.

Only Messages that utilize functions inside the PeopleCode function library FUNCLIB_EOEIP for their pre-processing, post-processing and subscription handler logic will have the order of processing logic enforced when using the parallel processing mode.
