Chapter 388
NW04S1300 Preparation Step:
Before installing the SAP Application Server 7.0 some OS-specific
parameters have to be adjusted. Verify or modify HP-UX kernel
parameters as recommended by NW04s Master Guide Part 1. Be sure to
propagate changes to all nodes in the cluster.
The SAP Installer checks the OS parameter settings with a tool called
“Prerequisite Checker” and stops the installer when the requirements
are not met.
NW04S1310 Preparation Step:
The SAP J2EE engine needs a supported and tested Java SDK on all
cluster nodes.
Check the installed Java SDK with the requirement as of the NW04s
Master Guide Part 1. Be sure to install the required SDK on all nodes in
the cluster.
In case the J2EE engine uses security features that utilize the need for
the Java Cryptographic Toolkit, it has to be downloaded both from the
Sun website as well as from the SAP Service Marketplace.
NW04S1320 Preparation Step:
Before invoking the SAP installer, some additional requirements have to
be met that are described in the SAP installation documentation for SAP
Application Server 7.0. These are not specific to cluster implementations
and apply to any SAP installation. They usually involve the setting of
environment variables for SAPINST, like the DISPLAY variable, the
temporary installation directory TMP, etc.
