Managing Serviceguard Extension for SAP on Linux (IA64 Integrity and x86_64), April 2009

SAP Netweaver 2004s High Availability System Installer
Installation Step: NW04S1330
The installation is done using the virtual IP provided by the Serviceguard package. SAPINST can be invoked
with a special parameter called SAPINST_USE_HOSTNAME.
This prevents the installer routines from comparing the physical hostname with the virtual address and drawing
wrong conclusions.
The installation of the entire SAP WAS 7.0 will happen in several steps, depending on the installation type:
• First, the SAP System Central Services Component (SCS and/or ASCS) will be installed using the virtual
IP contained in the corresponding Serviceguard package.
• Then, the database instance will be set up and installed on the relocatable IP address of the DB package.
• After that, the Central Instance and all required Dialog Instances are established.
The SAPINST_USE_HOSTNAME option can be set as an environment variable, using export or setenv
commands. It can also be passed to SAPINST as an argument.
cd <COMPONENT_TMP_DIR>
<SAPINST_MASTER_DVD>/IM<X>_OS/SAPINST/UNIX/<OS>/sapinst\
SAPINST_USE_HOSTNAME=<reloc_jci>
(A)SCS installation:
The SAP installer should now start.
Follow the instructions of the (A)SCS installation process and provide the details when asked by SAPINST.
It is necessary to provide the virtual hostname to any (A)SCS instance related query.
cd <DB_TMP_DIR>
<SAPINST_MASTER_DVD>/IM<X>_OS/SAPINST/UNIX/<OS>/sapinst\
SAPINST_USE_HOSTNAME=<reloc_db>
Database installation
The SAP installer should now be starting.
Follow the instructions of the database installation process and provide the details when asked by SAPINST.
It is necessary to provide the virtual hostname to any DB instance related query. After installing the RDBMS
software, SAPINST needs to be resumed and after finalizing the installation the SAP database setup is
complete. Install the latest database patch.
Installation Step: NW04S1340
The same procedure that uses virtual IPs provided by Serviceguard packages can be used for ABAP Central
Instance and dialog instance installations.
Both map to Serviceguard Extension for SAP on Linux package type (d).
