This appendix provides a step-by-step tutorial to guide you through a typical setup of a CPU capacity plan from building and collecting data for the capacity database to generating and presenting the forecast in presentation graphics. The tutorial uses the sample z/OS Processor Planning application, one of the many predefined views of resource consumption delivered by the CA MICS Capacity Planner, to assist you in collecting capacity planning data. However, your main capacity issue may require a different sample application, such as the one for DB2, CICS, or goal mode. In any case, this tutorial uses the CPU Planning application as an example to show you how to work with a typical sample Application. Before you begin, it is recommended that you review sections 2.0 and 2.1 of this guide. These sections describe the sample z/OS Processor Planning application and the types of data it collects for processor usage planning. Section 2.1 will help you understand the example that is used in this tutorial. However, if you need to use a different sample application, you must read another section of chapter 2. For example, you will need to read section 2.17 if you need to use the Goal Mode sample Application. While not required, a basic knowledge of the MWF (CA MICS Workstation Facility) and the MICF (CA MICS Information Control Facility) is helpful. This tutorial guides you through the Capacity Planner's online facility using MWF and discusses reporting interfaces in MICF. The z/OS Processor Planning sample Application that is described in this tutorial uses the MONTHS timespan of the HARCPU and WLMSEC files in the CA MICS database and archive tapes. You can substitute a different timespan in the actual planning process based on your requirements and database configuration. Assumptions ----------- o You have a basic knowledge of MICF. o You have reviewed sections 2.0 and 2.1 of this guide. o If you are going to use the z/OS Processor Planning sample application, the HARCPU and WLMSEC files must be available online or on CA MICS archive tapes. The MONTHS timespan is preferred for this example. o If you need to use another sample application, you can check the Usage Guidelines section for that application to find out what CA MICS files are required. Each sample Application that is described in Chapter 2 of this guide contains a section called Usage Guidelines that tells what CA MICS files are required. Introduction to the Exercise ---------------------------- This z/OS Processor sample application exercise provides CPU utilization statistics for performance analysis and can serve as input for future capacity planning forecasts. This procedure does not discuss option parameters such as Common Data Selection (Figure 2-3). These parameters can also be specified to subset the data further. The tutorial consists of four sections that are designed to help you: o Build the Capacity Database for CPU planning o Generate the CPU Forecast o Create the CPU Worksheet o Build Presentation Graphics
