4.1 Implementing WebSphere MQ Workflow Web Client
This section covers the installation, configuration, and validation of WebSphere
MQ Workflow Web client. We also cover the application server preparation and
the WebSphere MQ configuration.
The WebSphere MQ Workflow Web client enables a browser-based interface for
WebSphere MQ Workflow Runtime. This makes for easier WebSphere MQ
Workflow client setups (only the server changes, no client updates necessary)
and allows for a client concentrator machine to share WebSphere MQ workload
with the server. Furthermore, the client concentrator setup is necessary for
multiple WebSphere MQ Workflow Runtime servers to share a growing
You can also link the WebSphere MQ Workflow Web client feature to the
workflow server via WebSphere MQ Client connections. This opens a
WebSphere MQ Client connection from the WebSphere Application Server to the
workflow Runtime server for every client that needs workflow services.
The advantage of using a concentrator server is that it takes some of the
WebSphere MQ workload from the workflow Runtime server. Instead of a client
connection channel for every client that connects to the workflow system, there is
now only one pair of sending/receiving channels between the workflow
concentrator server and the workflow Runtime server.
Because WebSphere MQ Workflow inherently makes use of WebSphere MQ
cluster technology, a client concentrator setup also does load-balancing and
fail-over when needed.
Figure 4-1 on page 99 is a high-level graphic representation of all components
that are involved in this setup.
