► Ensure that the Ethernet interface to the external network is virtualized by z/VM through
an internal virtual LAN, called the z/VM VSWITCH.
► Use Quagga and ospf daemons for VIPA support and dynamic routing
– See the Quagga Routing Suite site at:
http://www.quagga.net/
– Use an NFS client for file sharing with AIX and z/OS UNIX System Services.
– Use SAMBA for file sharing with Windows.
Preparing for the SAP installation
You can now install SAP NetWeaver and the applications. Everything you need is on the
installation media that you download or receive from SAP.
To begin, follow these steps:
1. Start a PuTTY session or any other SSH terminal.
2. Run the SAPINST utility on the application server platform.
The SAPINST utility runs with root and administrator authority and uses a CLI or JDBC Driver –
DB2 Connect Lite or Thin Client to communicate with DB2 on z/OS. Any media with
NetWeaver 7 SR3 and later install the thin client.
Performing the post-installation steps for SAP
After the SAP code is installed and the database is created and loaded with the initial data,
you must perform several steps to complete the installation process. Some software parts
and agents, such as stored procedures, of the SAP system run in the z/OS environment
directly, which the SAPINST tool cannot access from the application server it runs on.
Perform the following post-installation steps:
1. Install SAP Operating System Collector saposcol, which is the required agent to collect
RMF and SMF data from the operating system.
2. Install the CCMS agent SAPCCMSR, which is the SAP CCMS console interface.
3. Install the SAP DB2 stored procedure SAPCL, which is the monitoring agent.
4. Obtain and install the SAP license. The license key is in the SAP shared file system.
5. Review the SAP profile parameters.
6. Remove DB2 ZPARM OFFLOAD if it was modified. Also verify the other ZPARMs.
7. Install the SAP support packages.
8. Make a client copy.
9. Back up the DB2 database by using the BACKUP SYSTEM DB2 command, which you can
also run to test if your backup procedures are working.
10.Back up the application server file systems.
The backup procedures depend on the application server platforms. For Linux on System
z, native, or under z/VM, you can use the DFSMShss utilities.
11.Create zFS aggregates if the file systems are on z/OS.
12.Download the latest build of DB2 Connect from the SAP Service Marketplace after installing
SAP. The SAPINST tool installs a DB2 Connect version from the supplied media that was
tested for the SAP installation. Newer versions are better suited for production work.
