have minimum support levels and thus must be reviewed to determine if they’ll r un properly under z/OS V1.9. IBM documents maintenance and release levels for many of its IBM products in Appendix B of “z/OS V1.9 Planning for Installation.” If some products are deficient, you’ll need to order the appropriate maintenance or version/release and add the related installation tasks to your migration plan. than three releases, you must devise a method for performing the upgrade without sharing resources between unsupported systems. Maintenance, Performance and Hardware Considerations Several aspects of z/OS V1.9 maintenance must be investigated: 1. Preventive Service Planning (PSP) buckets should be reviewed. This information can be accessed on www.ibm.com. Relevant buckets are: ZOSV1R9, ZOSGEN, SERVERPAC, and other z/OS components (BCP, JES2, etc.), and 20nnDEVICE (where 20nn is the processor model number). 2. You may need to apply driving system maintenance, or maintenance of the system where the installation jobs will run. For z/OS V1.7, you’ll need authorized program analysis report (APAR) number OA20599; no maintenance is needed for z/OS V1.8. 3. Coexistence maintenance must be installed on your existing z/OS V1.7 or V1.8 systems. The z/OS V1.9 migration manual documents the necessary coexistence maintenance. IBM also provides a tool to help determine whether coexistence maintenance is installed, called the Enhanced PSP Tool (EPSPT). Determine Your Installation Method Here’s a brief description of the three possible installation packages for z/OS (currently only SystemPac is available for z/OS V1.9, all three are available for z/OS V1.10): 1. ServerPac is probably the most popular software-delivery and installation offering. It includes product data sets, sample installation data sets and many installation and customization jobs. ServerPac is Interactive System Productivity Facility (ISPF) panel-driven method of running installation jobs, performing System Modification Program/Extended (SMP/E) and post-SMP/E steps, and performing tailoring or other installation steps necessary to create an IPL-able test system. 2. The Custom-Built Product Delivery Offering (CBPDO) is specially prepared for a specific product installation, including Once you’ve done your homework, creating a z/OS V1.9 migration plan is a fairly straightforward process. maintenance, as specified by the customer order. The CBPDO focus is installation; the only jobs it performs are unloading the data sets and applying service. The customer must perform the SMP/E installation work. 3. A SystemPac is similar to ServerPac, but it includes services to perform some or all installation tasks and postinstallation activities. EPSPT uses downloaded extract files from the appropriate z/OS release PSP bucket against an extract file created from your system to determine whether maintenance is on the system, and if not, what maintenance is required. 4. Target system maintenance, or maintenance to the system that’s being migrated to z/OS V1.9, may also be desirable. Maintenance will likely come with your z/OS V1.9 order, and an optional installation step is to apply it. As you prepare for production, you may want to order and apply all available non-hold maintenance, so you can test and move a current system into production. SOFTCAP is a free, as-is PC tool that provides software upgrade capacity assessment on a System z* platform. Supported products are: z/OS, CICS, IMS, TSO, batch and DB2. You can access multiple product releases. In addition, the “zSeries* Platform Test Report for z/OS and Linux* Virtual Servers” is another useful source. Hardware requirements are an impor tant par t of any migration. DASD requirements for z/OS V1.9 are 1,890 cylinders—approximately three 3390-6 devices. Target data sets need 6,400 cylinders, distribution library data sets require 8,900 cylinders and file system data sets call for 2,900 cylinders. 20 09 ibms ystemsmag .com/mai nframe 43 Identify Releases in the z/OS Migration This component of migration planning is simple, but can impact the migration’s complexit y. If your migration to z/OS V1.9 involves moving a system from a release lower than V1.7, there won’t be support for coexistence, fallback or migration. Coexistence is when systems at different releases of z/OS can share resources, either concurrently or at separate times. Fallback is when a system returns from a higher release level to a lower release level. Migration is the reverse of fallback, when a system is moved from a lower release to a higher release level with no incompatibility regarding system resources. IBM’s policy is to support three consecutive releases for coexistence/fallback/migration. If your migration involves more J U LY/A UGUS T
