IBM WebSphere Application Server has grown to be a successful application server platform. With IBM WebSphere Application Server on z/OS, the preferred application server platform gains the benefits of capacity and robustness from the mainframe legacy. It also gains access to data and transactions residing on z/OS subsystems such as DB2 and CICS.
In essence, the nature of the operating environment of WebSphere on z/OS is quite different from its distributed counterpart. UNIX System Services, although similar to a UNIX-like environment, has fundamental differences, such as workload management from z/OS Workload Manager, processes controlled by JES engine, and so on.
The aim of this IBM Redbook is to show and discuss the usage of various IBM/Tivoli products that help manage the IBM WebSphere Application Server on z/OS. The discussion consists of:
- Managing the performance of WebSphere resources using IBM Tivoli Monitoring (ITM) for Web Infrastructure
- Monitoring Web transaction performance using the IBM Tivoli Monitoring for Transaction Performance
- Ensuring high availability of WebSphere systems in a SYSPLEX environment using IBM System Automation
- Managing access using IBM Tivoli Access Manager for e-business--together with z/OS Security Server
We discuss concepts, implementation, and sample scenarios, and how these products can be used to manage IBM WebSphere Application Server on z/OS.
