Overview of a WebSphere Application Server for z/OS sysplex
A typical WebSphere Application Server for z/OS base run-time includes
a cell with a location service daemon (BBODMNB) and one node which includes
an Application Server (server1) with a controller and any number of servants.Once
you have installed the Application Server run-time and associated business
application servers on a monoplex, you can migrate the run-time and associated
application servers to a sysplex configuration. The benefits of migrating
to a sysplex include:
- You can balance the workload across multiple systems, thus providing
better performance management for your applications.
- As your workload grows, you can add new systems to meet demand, thus
providing a scalable solution to your processing needs.
- By replicating the run-time and associated business application servers,
you provide the necessary system redundancy to assure availability for your
users. Thus, in the event of a failure on one system, you have other systems
available for work.
- You can upgrade the Application Server from one release or service level
to another without interrupting service to your users.
