Setting the RFC_INI Environment Variable

You need to set the RFC_INI environment variable in Windows NT so that Siebel Tools or the Siebel Server can access the saprfc.ini file. Siebel applications open this file prior to connecting to SAP.

To set the environment variable

  1. Click the Windows Start button, and then choose Settings > Control Panel > System.

    The System Properties window opens.

  2. Navigate to the Environment fields.
    1. In Windows NT, click the Environment tab.
    2. In Windows 2000, click the Advanced tab, and then click Environment Variables.
  3. In the System Variable field, enter RFC_INI.

    The following figure shows the Environment tab with the existing System variables and User Variables, and the entry of the new RFC_INI variable.

  4. In the Value field, enter %SIEBEL_HOME%\BIN\saprfc.ini, where %SIEBEL_HOME% is the root directory of your Siebel installation.
  5. Click Set.
  6. Click OK.
  7. Restart Windows.
