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.

Minimum Java level

Java must be installed and operational on your z/OS system, z/OSMF V3R2 requires IBM® Semeru Runtime Certified Edition for z/OS® Version 21 at the required minimum level:
  • IBM Semeru Runtime Certified Edition for z/OS, 21.0.6.0 (5655-JB1)

This setup must be done before you configure z/OSMF. By default, the SDK resides in the directory /usr/lpp/java/J21.0_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.

The Central Processor Assist for Cryptographic Function (CPACF) must be properly installed and configured to support the OpenJCEPlus provider in Java 21 and later versions.

For more information, see the installation guides for IBM® Semeru Runtime Certified Edition for z/OS® Version 21.

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.

Web browser

The following web browsers are supported by z/OSMF, and are recommended for best results:
  • Google Chrome V111 or later (Windows 11, macOS 12.6 and later version)
  • Mozilla Firefox 102.9 or later (Windows 11, macOS 12.6 and later version)
