Table 3-1 Supported Platforms

Product	Version(s)
SAP R/3	3.1H and 4.5B

Where you install eLink Adapter for R/3 ALE depends on the node configuration:

• Single Node. If the R/3 environment is a single node configuration, then you should install BEA eLink Adapter for R/3 BAPI/RFC on that node.

• Multiple Nodes. If the R/3 environment is a multiple node configuration, then you should install BEA eLink Adapter for R/3 BAPI/RFC on one or more of the application servers. BEA eLink Adapter for R/3 BAPI/RFC must not be installed on the database server.

BEA eLink Adapter for R/3 BAPI/RFC interacts with R/3 using the SAP RFC library. The RFC library uses IP sockets to communicate with the R/3 application servers. Installing BEA eLink Adapter for R/3 BAPI/RFC on an R/3 application server node minimizes the risk of failure in this IP socket connection. If BEA eLink Adapter for R/3 BAPI/RFC is installed on an R/3 application server node, it is recommended that no other TUXEDO applications run on that same node, in order to reduce the workload on the node.

However, BEA eLink Adapter for R/3 BAPI/RFC can be installed on a node other than an R/3 application server. In this situation, the IP socket connection will transparently extend across the network to the R/3 application server.

BEA eLink Adapter for R/3 BAPI/RFC requires that you properly install and configure TUXEDO:

• Installation Node. TUXEDO must be installed on the node running BEA eLink Adapter for R/3 BAPI/RFC. For installation instructions, see the BEA TUXEDO Administrator's Guide for your platform.

• TUXEDO Configuration. After you install BEA eLink Adapter for R/3 BAPI/RFC, you must configure TUXEDO according to the instructions described in TUXEDO Initialization File. BEA eLink Adapter for R/3 BAPI/RFC provides a semi-configured TUXEDO initialization file, which requires only minimal configuration for the TUXEDO environment.
