Software prerequisites for z/OSMF

It is recommended that you complete the planning for z/OSMF before you configure it.

Be sure to obtain the latest PTFs; see Receiving service updates for z/OSMF.

The core services and optional services in z/OSMF have additional system set-up requirements. Enabling these services requires some customization of the z/OS host system, as described in z/OSMF core services and z/OSMF optional services.

  • IBM® 64-bit SDK for z/OS®, Java™ Technology Edition, V8 SR4 FP10 (5655-DGH).

This set-up must be done before you configure z/OSMF. By default, the SDK resides in the directory /usr/lpp/java/J8.0_64 on your system. If you installed it in another location, be sure to include the JAVA_HOME statement in your IZUPRMxx parmlib member, as shown in IZUPRMxx reference information.

WebSphere® Liberty profile

z/OSMF uses the Liberty Profile that is supplied with z/OS, rather than its own copy of Liberty. The WebSphere Liberty profile must be mounted on your z/OS system. The default mount point is: /usr/lpp/liberty_zos. To determine whether WebSphere® Liberty profile is mounted, check for the existence of the mount point directory on your z/OS system.

If WebSphere® Liberty profile is mounted at a non-default location, you must specify the location in the IZUSVR1 started procedure on the keyword WLPDIR=. For more information, see IZUSVR reference information.

Note: Whenever you apply PTFs for z/OSMF, you might be prompted to install outstanding WebSphere Liberty service. It is recommended that you do so to maintain z/OSMF functionality.
