About this task
To install the Liberty profile, you can use IBM® Installation Manager to install WebSphere® Application Server Version 8.5 or higher
with WebSphere eXtreme Scale, or you can
install the Liberty profile by
running a provided JAR file. If you install the WebSphere Application ServerLiberty profile using Installation
Manager, then you must also install WebSphere eXtreme Scale Version 8.5 or higher
using Installation Manager. Likewise, if you install the WebSphere Application ServerLiberty profile by running a JAR
file, then you must also install the WebSphere eXtreme Scale Version 8.5 or higher
product image by running a JAR file. On z/OS® operating systems, the Liberty profile provides an operations
environment. You can work natively with this environment using the MVS™ console. For application development,
consider using the Eclipse-based developer tools on a separate distributed
system, on Mac OS, or in a Linux shell
on z/OS.
