The ABAP queues are strictly First In First Out (FIFO) queues and are only processed by one Dialog work process at a time.

The queues in the Messaging System behave different then the qRFC queues in ABAP. The task of the Messaging System is to persist and assign resources for messages processed on the Java stack. For more information on Wily please refer to SAP Note 797147 and. Wily Introscope is a prerequisite for the analysis discussed below.

Note: All this information will also be made available in the next version of the PI performance check via SAP Note 894509. Newer versions have additional possibilities that will be explained where necessary. The description is valid for all SAP PI releases. This blog tries to summarize the aspects that have to be considered when tuning the Messaging System queues. Now, since all the steps like mappings and backend calls are executed in the same queue the tuning of the Java based Messaging System queues is now essential. Therefore for most of the scenarios Java only processing of messages is possible using Integrated Configuration objects (ICO).ДЇor classical ABAP based scenarios the parallelization was mainly triggered by adjusting the parallelization of the ABAP queues in the Integration Engine. With PI 7.3 also the IDoc and HTTP adapter will be available for Java. Most of the PI/PO adapters are running on Java.
