Update Capacity Provisioning to use Java 7.1 or higher
Description
Starting with z/OS V2R2, the Provisioning Manager component of Capacity Provisioning supports Java V7.1. If the references in the ENV member of the Provisioning Manager parameters data set specify the location of an earlier version of Java, you must update the LIBPATH environment variable.
Table 1 provides more details about the migration action. Use this information to plan your changes to the system.

Steps to take
Follow these steps:
- Install IBM 31-bit SDK for z/OS, Java Technology Edition, V7.1 (5655-W43).
- Change the LIBPATH variable in the ENV member of your Provisioning
Manager PARM data set to refer to the installation directories of
your Java V7 installation. For example:
