WebSphere Enterprise Service Bus for z/OS, Version 6.2.0 Operating Systems: z/OS


Messaging or queue destination hosts

A messaging or queue destination host provides the messaging function within a server. A server becomes the messaging destination host when you configure it as the messaging target.

A messaging engine runs within a server. The messaging engine provides messaging functions and a connection point for applications to connect to the bus. Service Component Architecture (SCA) asynchronous communication, JMS imports and exports, asynchronous internal processing use message queues on the messaging engine.

The deployment environment connects the message source to the message target through the bus when the application modules are deployed. Knowing the message source and message target helps you determine what type of deployment environment you need.

Applications can store persistent data in a data store, which is a set of tables in a database or schema, or in a file store. The messaging engine uses an instance of a JDBC data source to interact with that database.

Configure the messaging destination host when you define your deployment environment by using Server from the administrative console or designate the server as the destination host during software installation.
