System software planning SAP on the zEnterprise System requires a specific operating system, DB2 for z/OS database, and communication and utilities software component versions. Additional software is required for the application server environment alternatives, within the ensemble or in a discrete server environment. This minimum software is marked as “required” in Table B-7 on page 162. To improve the system capabilities and system management, additional software can be useful. This section describes these optional products and their purpose. Software for the SAP database server The SAP database server on System z and the zEnterprise System runs on a DB2 for z/OS database. The z/OS host has the SAP shared libraries installed on zFS and the SCS under z/OS UNIX System Services. Communication to the application servers routes through TCP OSD by using the Open Systems Adapters (OSAs) or in memory by using HiperSockets. In a high available configuration, the database server components, the SCS, and the shared libraries support the Parallel Sysplex cluster. For implementation details and required software, see Business Continuity for SAP on IBM System z, SC33-8206-04. Software for SAP NetWeaver Application Servers You can choose the application server platform for SAP. Because SAP supports virtualization on most application server platforms, your physical server can host several logical application servers. You also can mix SAP NetWeaver AS platforms within the landscape or within one SAP system. However, this practice is not recommended because it complicates the environment and the component variations. In the zEnterprise Ensemble of the ITSO lab, we used Linux on System z servers as guests to z/VM for one system, and AIX under IBM PowerVM on zBX blades for the other system. Required software Table B-7 lists all of the software and licenses that you need to run an SAP solution on System z or the zEnterprise System. This list is the bare minimum to get a system into production, although many clients use selected optional software to improve the availability security, and system management of their system. Ensure that you have all components or are in the procurement process, and everything is on an SAP supported level. SAP Note 81737: See SAP Note 81737 for the supported releases and fix levels. Table B-7 List of required operating systems, database, and tools software Software product Part number Comments System z as the database server z/OS 1.10, 1.11 or 1.12 with the following components configured: 5694-A01 Required as the host operating systems for DB2 for z/Os, z/FS, and z/OS UNIX System Services services for SAP. ► z/OS UNIX System Services z/OS base component, UNIX shell for z/OS. ► zFS z/OS base component, high performance UNIX files system, shareable. You can also use HFS. ► DFSMS/DFSMSdfp z/OS feature, z/OS storage management, includes a copy services function that is also useful to back up and restore SAP data. ► DFSMSrmm z/OS feature included with DFSMS. 162 Running SAP Solutions with IBM DB2 10 for z/OS on the IBM zEnterprise System
Software product Part number Comments ► DFSMShsm (see comment) z/OS feature, automated DASD storage management, including space management for low and inactive data.

You can use compatible products, such as CMF, that support the sysplex data services (ERBDSQRY, ERBDSREC, ERB2XDGS, and ERB3XDRS). z/OS security management system. Alternatively use any z/OS SAF compatible security products, such as ACF2 or Top Secret. Required DB2 stored procedures (except SAPCL) are in the base FMID and must be activated. See 3.6 in the SAP DBA Guide: DB2 for z/OS (V10). ► DFSORT For DB2 use If you do not use DFSORT in z/OS, make the DFSORT SORTLPA and SICELINK libraries available for use by the DB2 utilities.
