IBM WebSphere Application Server for z/OS Liberty Profile

The Liberty profile is a highly composable and dynamic application server runtime environment. Its fast restart time, small size, and ease of use makes the Liberty profile a great option for developers building applications that do not require the full Java Enterprise Edition (Java EE) environment. Applications built for the Liberty profile can be deployed to full profile WebSphere Application Server editions.

The Liberty profile is included in WebSphere Application Server for z/OS, which leverages the enterprise capabilities of System z and z/OS to deliver the availability and security that your business applications depend on. In fact, there are unique features within the Liberty profile on z/OS that take advantage of System z qualities of service, such as z/OS security, transactions, and workload management. The trial of the Liberty profile on z/OS provides an opportunity to evaluate the benefits provided by this lightweight and dynamic application server in the context of a z/OS environment.


This is a trial of the Liberty profile on z/OS. Download the trial for an evaluation period of 60 days. The trial download includes the Liberty profile capabilities delivered in WebSphere Application Server v8.5.5 with the additional z/OS specific features for security, transactions, and workload management. These capabilities are also available as a service release on WebSphere Application Server for z/OS v8.5.
