Configuring TREXNet for Secure Communication

You configure the TREX servers for secure communication with each other (using TREXNet) by configuring the sapprofile.ini INI file.

Procedure

1. Open the usr/sap/<SAPSID>/TRX<instance_number>\<TREX_directory>\sapprofile.ini configuration file on the TREX Web server with a text editor.
2. In the # secure communicationsection, set the TREX/Net/Secure= parameter to yes (default: No)
3. In the same section, enter the name of the keystore for the TREX/Net/ListenCredential= parameter.

   You can specify the SAPSSLS.psekeystore here. This contains the certificates for communication between theTREX preprocessor and the Web server. However, you can also leave the entry for the TREX/Net/ListenCredential= parameter empty, since the SAPSSLS.pse keystore is used by default.

   Tip

   # secure communication

   TREX/Net/Secure=yes

   TREX/Net/ListenCredential=SAPSSLS.pse

4. Restart TREX so that the changes to the configuration file sapprofile.ini are accepted by TREX.
5. Windows only: Restart the IIS (Internet Information Server).

Result

You have configured secure communication between the TREX servers using TREXNet.
