|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 C9.2e (package includes Java). This is necessary to facilitate conversion to the new IBM Java v8 64-bit runtime environment that is required for zPCR.
To review the zPCR C9.2e NEWS file, click on What's New below.

Frequently Asked Questions
How are the IBM z14 models identified?
How are the IBM z13 models identified?
How are the IBM zEnterprise EC12 models identified?
How are the IBM zEnterprise 196 models identified?
How are the IBM System z10 EC models identified?
How are the IBM System z9 EC models identified?
The IBM System z9 EC has 5 models. The models support different number of processor units (PU) which are configurable as General Purpose CPs, zAAPs, zIIPs, IFLs, ICF's, or optional SAPs.
System z9 EC Models S08 - Supports 1 to 8 Configurable PUs
S18 - Supports 1 to 18 Configurable PUs
S28 - Supports 1 to 28 Configurable PUs
S38 - Supports 1 to 38 Configurable PUs
S54 - Supports 1 to 54 Configurable PUs
In addition, for General Purpose CPs, there are 4 engine speeds, listed below in increasing speed sequence. All zAAPs, zIIPs, IFLs, and ICFs are full speed CPs.
400 Limit of 8 General Purpose CPs
500 Limit of 8 General Purpose CPs
600 Limit of 8 General Purpose CPs
700 No limit for General Purpose CPs
How are the IBM zSeries 990 models identified?
How often will I need to register my use of zPCR?
Registration is required to begin using zPCR. Subsequent registration for zPCR will only be required on a version change. This is expected to happen very infrequently. New releases or modification levels of zPCR will be made available on a regular basis but these updates will not require the user to register again.
What versions of Windows will support zPCR?
When must I reinstall the IBM Java runtime environment?
