The configuration of the WebSphere MQ-bridge requires you to perform some
actions on the WebSphere MQ queue manager, and some on the WebSphere MQ
Everyplace queue manager. The bridge is logically broken into two
pieces, one for each direction of the message (WebSphere MQ Everyplace to
WebSphere MQ and WebSphere MQ to WebSphere MQ Everyplace)
The bridge objects are defined in a hierarchy as shown in Figure 19
The following rules govern the relationship between the various
objects:
- An WebSphere MQ Everyplace bridges object is associated with a single
WebSphere MQ Everyplace queue manager.
- A single WebSphere MQ Everyplace bridges object may have more than one
bridge object associated with it. You may wish to configure several
WebSphere MQ-bridge instances with different routings.
- Each bridge can have a number of WebSphere MQ queue manager proxy
definitions.
- Each WebSphere MQ queue manager proxy definition can have a number of client connections that allow communication with WebSphere MQ
Everyplace.
- Each client connection connects to a single WebSphere MQ queue manager. Each
connection may use a different server connection on the WebSphere
MQ queue manager , or a different set of security, send, and receive exits,
ports or other parameters.
- A WebSphere MQ-bridge client connection may have a number of transmission queue listeners that use that
bridge service to connect to the WebSphere MQ queue manager.
- A listener uses only one client connection to establish its connection.
- Each listener connects to a single transmission queue on the WebSphere MQ
system.
- Each listener moves messages from a single WebSphere MQ transmission queue
to anywhere on the WebSphere MQ Everyplace network, (through the WebSphere MQ
Everyplace queue manager its bridge is associated with). So a WebSphere
MQ-bridge can funnel multiple WebSphere MQ message sources through one
WebSphere MQ Everyplace queue manager onto the WebSphere MQ Everyplace
network.
- When moving WebSphere MQ Everyplace messages to the WebSphere MQ network,
the WebSphere MQ Everyplace queue manager creates a number of
adapter objects. Each adapter object can connect to any
WebSphere MQ queue manager (providing it is configured) and can send its
messages to any queue. So an WebSphere MQ-bridge can dispatch WebSphere
MQ Everyplace messages routed through a single WebSphere MQ Everyplace queue
manager to any WebSphere MQ queue manager.
