IBM SCA destinations for IBM Business Process Manager (BPM), WebSphere Process Server (WPS) and WebSphere Enterprise Service Bus (WESB) are not preserved when uninstalling and reinstalling a service module - United States SCA.RecycleDestinations; custom properties; SCA destinations; event sequencing; SCA modules; message queue TECHNOTE (TROUBLESHOOTING)

PROBLEM(ABSTRACT)
 When a Service Component Architecture (SCA) module is uninstalled, by default, its associated destinations are removed, even if there are still messages in the destination queue. In some situations, such as when Event Sequencing is used, messages on the destinations must be preserved.



RESOLVING THE PROBLEM
To resolve this issue, use the SCA.recycleDestinations custom Java™ virtual machine (JVM) property for the module. Set the property to false to preserve SCA destinations.

Updating SCA applications & internal SCA module queues When updating an existing SCA module using the ISC, I noticed that internal SCA queues (sca/<module>/...) on the SCA.SYSTEM bus) are deleted and recreated.  One can potentially loose messages on these queues. Is there a fix to the problem?
