JMS Message Lost in Automatic JMS Listener after Database Connectivity Problems
Last updated on MARCH 08, 2017
Applies to:Oracle Business Process Management Suite - Version 6.0.4 and later
Information in this document applies to any platform.
There is a Global Automatic JMS Listener , with Auto Acknowledge selected. This activity receives a message from an external JMS queue( for e.g. on weblogic). When a new JMS message arrives, ProcessInstance.create() is called inside this activity to create a new instance.
Due to network issues, engine lost connectivity to the database and PBL code ProcessInstance.create() fails inside Listener. In this scenario, it is seen that corresponding JMS messages are lost and engine is not able to retry creation of these instances. How does JMS Listener behave in this scenario and how can we prevent this from happening ?
