WAS for z/OS Liberty Profile

Liberty profile is a new application server run-time model that is available on all platforms supported by the WebSphere Application Server V8.5 product.

The IBM WebSphere Application Server „Liberty Profile” is a significant new approach to application serving. The Liberty Profile is designed to be composable, lightweight, dynamic and fast: Liberty is small, lightweight, highly composable, fast-to-start, dynamic application server runtime environment, with simple configuration. It can be deployed and started in seconds so it’s an ideal Java runtime for the cloud.

Liberty for z/OS provides the same features as Liberty on other platforms along with independently enabled extensions that exploit z/OS facilities such as Workload Manager (WLM), Resource Recovery Services (RRS) and System Access Facility (SAF), which provides close integration with the z/OS operating system.

WebSphere Liberty for z/OS provides the base infrastruture for z/OS Connect and WOLA which enables z/OS systems such as CICS and IMS to better and more easily participate in today’s Mobile computing environment.

This course introduces the WebSphere Application Server Liberty Profile on z/OS and covers installation and configuration. It describes how to install and administer a Liberty profile server as a started task, along with command-line scripts. The course also explains how to manage and monitor a Liberty for z/OS server environment.
