15 Heterogeneous SAP System Installation

15 Heterogeneous SAP System Installation
Use
This documentation describes how to install SAP instances in a heterogeneous UNIX
environment, that is:
•

You run instances on different UNIX platforms.

•

You mix 32-bit instances and 64-bit instances in one landscape.

This section does not apply to installations of SAP instances in a mixed UNIX /

Windows NT environment. See the documentation SAP Basis Installation on
Windows NT for more information.

Procedure
Local Software Installation

Proceed as follows to store the SAP executables locally:
1. Install the central instance and the database as described in the documentation
SAP Basis Installation on UNIX.
2. Log on as user root on the dialog instance host.
3. Create <sapmnt>/<SAPSID>/exe as a local directory on the dialog instance.
4. On the central instance host, export the directories <sapmnt>/<SAPSID>/global and
<sapmnt>/<SAPSID>/profile via NFS and mount them on each dialog instance host as
described in section Mounting directories via NFS.
5. Mount the CD drive (via NFS) and insert the CD with the SAP executables on the dialog
instance host.
6. Install the dialog instance.

Shared Software Installation

It is also possible to perform a shared software installation. The executables are installed in a
differently named directory on the server and mounted via NFS. Shared software installation
makes upgrading and maintenance of SAP software easier while producing a greater load on the
network.
To perform a shared software installation, install the executables of dialog instance hosts on
different platforms to the central instance host on the central instance host in the directories
<sapmnt>/<SAPSID>//exe (/sapmnt/BZ6/AIX_32/exe for example)
and NFS export the directories in read-write mode. On the dialog instance host, create
<sapmnt>/<SAPSID>/exe, <sapmnt>/profile and <sapmnt>/global as a NFS mount
to the corresponding directories on the central instance host (<sapmnt>/<SAPSID>/exe must

be a link to <sapmnt>/<SAPSID>//exe created above on the central instance

host). Now, install the dialog instance. Take account of the following aspects during the dialog
instance installation:
•

During the installation of the first dialog instance of a platform, R3SETUP must be forced to
copy the correct executables from CD-ROM to the directory <sapmnt>/<SAPSID>/exe
(which is <sapmnt>/<SAPSID>//exe on the central instance host).

•

In the command file for R3SETUP, specify the key EXTRACT_ON_NFS=YES in the steps that
extract SAPEXE.SAR and SAPEXEDB.SAR. (When installing additional dialog instances of
this platform, do not specify this key.)
