2. Prepare the SAP NetWeaver AS:<br />
a. Set up z/VM as the Linux on System z AS host.<br />
b. Prepare the Linux on System z application server.<br />
c. Prepare the AIX application server.<br />
d. Prepare the Windows application server.<br />
3. Prepare the network.<br />
a. Prepare the basic network setup for a quick installation.<br />
b. Make considerations for near continuous availability options.<br />
4. Install the SAP application. See 4.1, “Installing Linux on System z, SAP, and DB2” on<br />
page 54.<br />
5. Perform basic SAP post installation steps.<br />

Building the SAP database server environment<br />
During our detailed design, we created a layout of the server landscape including the<br />
database server LPARs. Regardless of whether you plan to run the database server on a<br />
stand-alone zEnterprise complex or in an ensemble, use the zEnterprise hardware<br />
management console (HMC) and the <strong>IBM</strong> zEnterprise Unified Resource Manager to create<br />
the LPARs. Your systems programmer must define, create, and activate the LPARs according<br />
to the plans, assign main storage (memory), CPs, zIIPs, and DASD FICON connections. Also<br />
initiate the basic hardware networking setup (for OSA cards, intraensemble data network<br />
(IEDN), and so on). HiperSockets communication is part of the setup for communications.<br />
Then the storage administrator must set up the required disk space, including the emulated<br />
DASD volumes. Also activate the parallel access volume (PAV), FlashCopy, and mirroring in<br />
the storage subsystem.<br />
The hardware is now ready for installing the software.<br />
Preparing the z/OS environment<br />
To install and prepare the z/OS environment for the database server hosting LPARs:<br />
1. Install z/OS (1.12) and all related components.<br />
2. If you are running SAP Central Services instance (ASCS, SCS) on z/OS, configure the<br />
z/OS UNIX System Services (BPXPRMxx). See 3.2.3.2 in the Planning Guide SAP on<br />
<strong>IBM</strong> DB2 for z/OS, version: 2.50 - 2011-10-01.<br />
3. Determine a method of database-to-application server communication, such as whether to<br />
implement an internal or private network.<br />
zEnterprise Ensembles: Consider using the IEDN ensemble secure network for SAP<br />
SCS communication. Use the Unified Resource Manager to configure the network<br />
where possible.<br />
4. Review and apply SAP Note 595331- Enhanced ASCII Support/FTP:<br />
a. Disable SMF Record Type 92. This record tracks zFS file activities and affects<br />
performance because of extensive zFS usage by SAP.<br />
b. Optional for HA: Set up the shared file system in Parallel Sysplex. See Business<br />
Continuity for SAP on <strong>IBM</strong> System z, SC33-8206-04.<br />
