How to Install SAP and the Database

Use this procedure to install SAP and the database.

1. Become superuser on one of the nodes in the cluster where you are installing the central instance.

2. Install SAP binaries on a cluster file system.

   If you are installing SAP 7.0 or NW2004 SR1, use the logical host when installing the software. During configuration you will be asked to skip all the steps that ask you to change the `references to physical hosts' to `references to logical hosts'. These updates to file names and file contents with such references are not required, because when you install SAP 7.0 or NW2004 SR1 using the logical host, the SAP installer creates files and file contents using the logical hostname. Thus the updates are already taken care of.

   Note –

   Before you install SAP software on a cluster file system, use the scstat(1M) command to verify that the Sun Cluster software is fully operational.

   1. For all the SAP-required kernel parameter changes, edit the /etc/system file on all the cluster nodes that will run the SAP application.

      After you edit the /etc/system file, reboot each node. See the SAP document R/3 Installation on UNIX-OS Dependencies for details about kernel parameter changes.

   2. See the SAP document Installation of the SAP R/3 on UNIX for details about how to install the central instance, the database, and the application server instances.

      See How to Install and Enable an SAP Scalable Application Server for the procedure on how to install a scalable application server in a Sun Cluster environment.
