Step 3: Configure the server
You can create multiple WebSphere Application Server instances (each containing a single application server) on a single iSeries server. You can also use multiple instances to create separate environments for application development and application testing. It is recommended that you create a new Websphere Application Server instance to configure the message-driven beans application sample in order to preserve the Default Server with its sample configuration.
Create a new instance
Create a new WebSphere Application Server instance to run the sample application.Enable your instance to use Java Message Service (JMS)
The instance you created must be configured with Java Message Service resources before the application can be deployed to the instance.Set up security (optional)
The WebSphere Application Server security system controls access to resources and the administrative console. Perform this step to enable security.
