Checking an RFC Connection

If the connection test fails when you create an RFC destination or search server relation, check the following:

• Gateway

• RFC destination

• TREX Configuration

Checking the Gateway

On UNIX

1. Check whether the process gwrd is running:

   ps -fu <gwsadm> | grep gwrd

2. Check whether the group that the user belongs <gwsadm> to has the access rights rwx for the directory /usr/sap/<SAPSID>/TRX<instanznummer> .

On Windows

1. Use the Task Manager to check whether the process gwrd.exe is running.

2. Check the settings for the gateway service. To do this, choose the following paths:

   • Windows 2000:  Start  Settings  Control Panel  Administrative Tools  Services .

   • Windows Server 2003:  Start  Administrative Tools  Services .

   If the service SAPGWS_<SAPSYSNR> does not run, start the service. If necessary, change the start type of the service so that it starts automatically.

3. Open the SAP System Management Consoleover  Start  Programs  or  All Programs  SAP System Management Console . Check whether the gateway instance has started. If necessary, start the gateway instance using  Action  Start .

Checking the RFC Destination

Check the data that you entered when creating the RFC Destination (see Configuring and Administrating the RFC Connection) Pay attention to lowercase and uppercase letters in the input parameters.

Checking the TREX Configuration

Check the gateway parameter in the file <TREX_DIR>/<TREX_host_nummer>/TREXRfcServer.ini:

• Is the host name of the host on which the gateway is installed correct?

• Does the instance number match the number you specified during the gateway installation?

[CONNECTION]

HOST=<local_host_or_host_name>

INSTANCE=sapgw<gw_instanznummer>
