Configuring TREXNet for Secure CommunicationLocate this document in the navigation structure


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

  1. Open the usr/sap/<SAPSID>/TRX<instance_number>\sapprofile.ini configuration file on the TREX Web server with a text editor.

  2. In the # secure communication section, set the TREX/Net/Secure= parameter to yes (default: No).

  3. In the same section, enter the name of the keystore for the parameter TREX/Net/ListenCredential=.

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


    # 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).


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