Hi Vipul

Trex is a search engine that you need to install and also need to register trex with portal to search KM documents from portal.

To register TREX hosts with the Portal, you have to first locate the name server and port of the TREX Installation. This is located in sapmsg.ini. You have to then set up the TREX name server in the J2EE Engine with the Visual Administrator.

To locate the name server and port

.Log on to the server as an Administrator .

.Navigate to the installation folder of TREX (that is C:\usr\sap\trex_00).

.Double-click sapprofile.ini to open the file in Notepad.

.Make a note of the port number. The default is 30001.

.You will need to enter this port number to the J2EE Visual Administrator in a later step.

Trex/Nameserver/Port=30001

To set up the TREX name server in the J2EE Engine

.Open Windows Explorer in the server.

.Navigate to J2EE Admin installation directory (that is C:\usr\sapSID\JC##\j2ee\admin).

.Double-click go.bat to start the J2EE Visual Administrator.

.Log on to Visual Administrator.

.Choose Global Configuration u00E0 Services u00E0 TREX Service.

.Select the nameserver.address properties field.

.Enter the server name of the TREX instance and the port number.

Choose Update.

Choose Save

.Select yes to restart the TREX Service.

To exit the J2EE Visual Administrator, choose Close u00E0 Exit.

Check the connection to the Enterprise Portal

Log on to the Enterprise Portal with super-administrator permissions.

Choose System Administration u00E0 Monitoring u00E0 Knowledge Management u00E0 TREX Monitor u00E0 Server Status.

You should see the status of the HTTP Server, Name Server, Queue Server, and Index Server is Available.

For Connecting TREX to Remote System

u00B7 The TREX admin tool and the remote system have the same TREX release.

u00B7 The TREX admin tool can reach the remote system via the network.

u00B7 You know the user name and password for the remote system.
