Abstract: zSoftCap is PC-based tool that will evaluate the effect on IBM Z processor capacity when migrating to newer levels of software, including z/OS, z/VSE, CICS and IMS. zSoftCap assumes that the hardware configuration remains constant while the software version or release changes.

If your currently installed zSoftCap version is older than C5.0, it MUST be uninstalled prior to installing zSoftCap C5.4a (package includes Java). This is necessary to facilitate conversion to the IBM Java v8 64-bit runtime environment that is required for zSoftCap.
