This course is designed for WebSphere Application Server (WAS) systems support staff who need to plan to make use of the Intelligent Management capabilities in WAS 8.5.
Delegates will need good hands on knowledge of WebSphere Application Server Network Deployment, including the installation and configuration of clusters, applications, IBM HTTP Server. WebSphere Application Server V8.5.5 Administration - WA855G provides an ideal basis for this.
1 day, consisting of lectures, discussions and hands-on lab exercises.
This course is available on site only. Please call for details.
NOTE: This course is can combined with our WebSphere Application Server V8.5.5 Administration - WA855G course and run over five days, please contact us if you would like this option.
The intelligent management features of WebSphere Application Server V8.5, which were previously sold separately by IBM as WebSphere Virtual Enterprise, provide the following high-value benefits:
- Applications with health problems such as memory leaks can be run in production without impact to end-users. Impending problems are detected and action taken pro-actively to restart servers, capture dumps etc.., before a failure affects users.
- The application server can automatically manage the allocation of server resources to applications against pre-defined response time targets. This provides more consistent performance for the most critical applications while also allowing servers to be run at greatly increased utilisation levels.
- An Application Edition Manager feature enables the introduction of new application releases in a controlled manner that involves no interruption of service to users, makes it very easy to roll-back to a previous edition if necessary, and allows the piloting of new editions on selected groups of users (e.g., internal users), before rolling them out generally.
These powerful capabilities make it possible to provide a more reliable and responsive service to users and reduce the cost of hardware and software licences needed to provide the service.
At the end of this course, delegates will:
- Understand the capabilities of the Health Management, Dynamic Clustering and Application Edition Management features of WAS ND 8.5.
- Be familiar with configuring health policies.
- Be familiar with configuring and managing dynamic clusters and service policies and deploying applications to take advantage of these.
- Understand the role of On-Demand Routers (ODRs) and be able to install ODRs in a resilient configuration.
- Know where to find further information, including formal documentation, relevant redbooks and support routes.
