SAP Netweaver 2004s High Availability System Installer
NW04S1330 Installation Step:
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.
