How can we do asynchronous logging in a Servicce ?

Question

For performance reasons we may want to make logging asynchronous what are the possible ways of accomplishing it in a BPM service.

Answer 1

Hi. You can create an "utility service" (in a toolkit) that use the JMS/MQ connector (part of the BPM provided "Integration.jar") to "write" the log on a queue (a JMS queue or a WebSphere Queue). This is a fast and asynchronous way to log messages.

Another application can "dequeue" the messages from the queue and manage the informations as required (eg. put them on a relational DB).

Answer 2
