JBI Environment

Note – The logging levels for JBI Components are often inherited from a parent logger such as the JBI logger. To view and set parent logging levels, in the Admin Console, select Common Tasks and then Application Server. Then, in the Enterprise Server panel, select Logging and then Log Levels. Look for the drop-down list for the JBI module to view and set the parent JBI logging level.

Service Assemblies

A Service Assembly is a collection of Service Units that provision target components that together provide or consume specific services for an application. Service Assemblies are typically created in a development tools environment, such as that provided by NetBeans Enterprise Pack.

A Service Assembly has the following lifecyle states:

■Started

■Shutdown

■Stopped

The JBI Runtime persists the lifecycle states of Service Assemblies. When the Enterprise Server shuts down and then restarts, Service Assemblies revert to their state at the time the Enterprise Server shut down.

Note – The JBI runtime attempts to revert to the "desired" state of a Service Assembly. For example, suppose you tried to start a Service Assembly but it did not start due to an error in the Service Assembly. If you restart the Application Server, the JBI runtime attempts to start the Service Assembly again.

You can do the following operations on Service Assemblies. For detailed steps, log on to the Admin Console, navigate to the JBI node, click Service Assemblies and then click Online Help.
