Abstract: This is the Getting Started page for those interested in using IBM's Processor Capacity Reference (zPCR) to capacity plan for IBM Z and LinuxONE processors. It includes links for accessing related educational materials and downloading the tool itself.

If the tabs of this notebook don't work for you, try this version of the document.

Note: If your currently installed zPCR version is older than C9.0, it MUST be uninstalled prior to installing zPCR C9.3a (package includes Java). This is necessary to facilitate conversion to the new IBM Java v8 64-bit runtime environment that is required for zPCR.

zPCR - Processor Capacity Reference for IBM Z

zPCR is a PC-based productivity tool under Windows. It is designed to provide capacity planning insight for IBM Z and LinuxONE processors running LPAR configurations with various workload environments under z/OS, z/VM, z/VSE, KVM, Linux, zAware, zACI, SSC, and CFCC. Capacity results are based on IBM's LSPR data supporting all IBM Z and LinuxONE processors including the new IBM z15 Model T01 and LinuxONE III processor families.
