This section describes how to install BEA eLink Adapter for R/3 BAPI/RFC on UNIX and Windows NT systems. It covers the following main topics:

• Installing on a UNIX System

• Installing on a Windows NT System

Installing on a UNIX System

Installing eLink Adapter for R/3 BAPI/RFC on UNIX systems requires the three main steps:

• Creating the conr3 User

• Logging In as con3

• Running install.sh

Creating the conr3 User

A UNIX user with non-administrative privileges should be created on the R/3 application server to provide a context in which to run both TUXEDO and BEA eLink Adapter for R/3 BAPI/RFC. This user should be used to run TUXEDO and BEA eLink Adapter for R/3 BAPI/RFC only so that processes associated with TUXEDO and BEA eLink Adapter for R/3 BAPI/RFC can be identified easily.

BEA suggests that you use conr3 for the user name. This document refers to this UNIX user as conr3 . If your organization uses a different user name, then substitute your user name whenever you encounter a reference to conr3 in this document.

Note: BEA strongly recommends that you do not use the UNIX R/3 administration user (nnnadm, where nnn represents the R/3 system identifier) to run TUXEDO and BEA eLink Adapter for R/3 BAPI/RFC.

After creating the conr3 user name, log in as that user.

Run the install.sh script to install the BEA eLink Adapter for R/3:

1. Insert the CD-ROM in the CD-ROM drive.

   If your system is not already configured to access data from a CD-ROM directory, you will need to create a mount directory (for example, mkdir /cdrom ) and mount the CD-ROM device (with the mount command).

   Change directories to your CD-ROM directory using the following command:

   cd /cdrom 

2. Type ls to view the contents of the CD.

   The CD should contain the following files and directories:

   HPUX/   IBM/   install.sh   readme.txt   SUN5X/   WINNT/

3. Start the installation by typing the following at the command line prompt:

   sh ./install.sh

   Press Enter.

   This invokes the installation script.

   The UNIX system installation script provides a set of step-by-step instructions to help you quickly install the BEA eLink Adapter for R/3. This script lets you specify your platform, operating system, and the directory where you want to install. The installation script prompts you through the entire installation process. You can cancel the installation at any time by pressing CTRL-C simultaneously.

4. Type the number that corresponds to the name of the operating system you are using (for example, if using HPUX1020, type 1 ).

   01) HP/HPUX1020    02) HP/HPUX1100      03) IBM/AIX414   
   04) IBM/AIX421     05) IBM/AIX43        06) SUN5X/SOL251  
   07) SUN5X/SOL26

   Install which platform's files? [01-5, q to quit, l for list]: 2

   Press Enter.

5. You are prompted to confirm your choice. If correct, type y for "yes," or n for "no" or q to "quit." Press Enter.

   ** You have chosen to install from HP/HPUX1100 **
