Configuring the RFC Connection in the TREX Admin Tool 

Use

You work through the steps below using the TREX admin tool (stand-alone).

 

Creating a Connection

...

       1.      In the Landscape RFC window, choose the Create Connection function.

       2.      Choose connection type A or B. Specify the connection data for the SAP system (see Determining the Connection Data for the SAP System).

       3.      Specify the SAP system user, the associated password, and the client that the TREX admin tool is to use to log on (see Defining the SAP System Users).

 

If the SAP system user in question exists in the default client, you do not need to specify the client.

 

Creating an RFC Destination

...

       1.      In the Landscape RFC window, choose the RFC Destination (SM59) function.

 

       2.      Enter the following parameters:

Field	Entry
SAP System	SAP system that you want to set up the connection to. The list contains all SAP systems that you have registered using Create Connection.
RFC Destination	Name of the RFC destination.
Description	Meaningful description of the purpose

The program ID determines under which name the TREX RFC server registers with the SAP gateway. The program ID must be unique for each SAP gateway. The TREX admin tool ensures this by generating the program ID.

 

       3.      Decide which SAP gateway you want to use. You have the following options:

Option	Comments
Gateway local (Default setting)	Use local SAP gateways for the application servers.
Gateway central	Use the central SAP gateway. SAP advises against using a central SAP gateway for distributed TREX systems. The central SAP gateway is a “single point of failure.” If you choose this option, enter the following additional parameters: ·        Host name (with domain name if necessary) or the IP address of the host on which the gateway is installed. ·        Name of the gateway in the form sapgw<instance_number>

 

SAP advises against creating the RFC destination directly in the SAP system. The name of the RFC destination and the program ID must satisfy certain naming conventions. The TREX admin tool ensures that these are fulfilled.

If you nevertheless create the RFC destination directly in the SAP system, note the following:

·         SAP recommends starting the name of the RFC destination with TREX_.

·         Choose the activation type Registered Server Program.

·         Choose a program ID that is unique for the SAP gateway used.

·         Use the RFC Destinations function to register the RFC destination in the TREX admin tool.

 

Completing the RFC Configuration

...

       1.      In the Landscape RFC window, choose the Connect function.

The TREX admin tool creates the connection to all SAP systems that are known to it. Because the RFC configuration is still incomplete, the configuration status is  yellow or  red.

 

       2.      Choose Repair All.

The TREX admin tool completes the RFC configuration and starts the TREX RFC server.

This can take several minutes. During this time, the configuration status remains  yellow or  red. After completion of the configuration process, the status changes to  green.

 

Do not choose Repair All several times in quick succession. This would trigger the configuration process more than once and delay it.

 

       3.      Check the progress by choosing Refresh to update the display.
