Book description
In this IBM Redbooks publication, we describe how to configure
the various components of an e-business solution to exploit the
availability and scalability benefits of zSeries and Parallel
Sysplex using multiple LPARs running Linux for zSeries and
z/OS.
This publication applies to WebSphere for z/OS V6, and is a
continuation of the project evaluating high availability using
WebSphere for z/OS V5 and V4. Presented in three parts (theory,
systems setup, and availability tests), we cover workload
balancing, the use of HTTP sessions, various architectures, and how
to set up and test your infrastructures.
Considerations for configuring the systems and applications in an
e-business environment are also examined, and we address such
questions as:
- Should there be separate front-end systems for running the
WebSphere Application Server?
- How should e-business components be configured to minimize or
eliminate the impact of a system outage?
- What is the best way to communicate between the WebSphere systems
and the back-end application systems?
- What is the impact on the end user if there is a failure in one
of the front-end or back-end systems?
