Multi-Purpose Listener (MPL) Worker Processing Limit Definition (Doc ID 2072207.1)

Last updated on MARCH 18, 2019

Applies to:

Oracle Utilities Customer Care and Billing - Version and later
Information in this document applies to any platform.


In CC&B 2.2, in order to control the number of connections to the database, as well as some order-of-processing issues, we found we had a need to control the number of messages processed concurrently by an MPL worker, with different values based on the type of receiver. This was controlled by adding a startup parameter in the script where we added the following options:

JAVA_OPTIONS="$JAVA_OPTIONS -Dspl.mpl.downloadStagingTableReceiver.batchProcessSize=5"
JAVA_OPTIONS="$JAVA_OPTIONS -Dspl.mpl.outboundMessageReceiver.batchProcessSize=5"
JAVA_OPTIONS="$JAVA_OPTIONS -Dspl.mpl.stagingTableReceiver.batchProcessSize=1"

Since we've upgraded to CC&B 2.4, these options  ignored.

The worker processes are picking up 100 messages no matter what type of receiver based on the default XAI Option setting for concurrent messages.
