Configuring TREXNet for Secure Communication 

Use

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 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 TREX/Net/ListenCredential= parameter.

You can specify the SAPSSLS.pse keystore here. This contains the certificates for communication between the TREX 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.

# 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.
