Activity

Start the TREX Admin Tool

You need the TREX admin tool (stand-alone) for post-installation configuration steps. As of TREX 7.1 the TREX admin tool runs independently of the TREX servers and services.

TREX starts automatically if you restart the host.

If you have not restarted the host, start TREX manually (see Starting and Stopping TREX on UNIX).

HTTP communication

Configure the TREX Web Server

Java applications communicate with the TREX servers using HTTP/HTTPS by means of the TREX Web server. After installing TREX, you have to configure the TREX Web server so that your Java application can access TREX.

Configure TREX Proxy Settings

If there is a proxy server between the TREX servers and the documents to be indexed, specify the proxy server and define exclusion rules if necessary.

TREX Languages

Select Languages for TREX Language Recognition

TREX supports the indexing and analysis of documents in different languages. You select languages to be identified by TREX language recognition.

System Landscape Directory

Configure TREX for the System Landscape Directory (SLD)

General Windows Configuration

Check Performance Settings for the Operating System (Windows)

On Windows no further actions are needed to start TREX. The SAP service for the corresponding TREX instance is registered as a Windows service and starts automatically after installation.

Connecting TREX with a HTTP Application

Specify the Address of the TREX Name Server

Enter the address of the TREX name server in the Java client configuration settings (TREX service in the NetWeaver Administrator of the JEE).

Check Proxy Settings

If an application is unable to communicate with TREX, it may be due to the application trying to access TREX through a proxy server.

Wizard-Based Configuration

Wizard-Based Basic Configuration for TREX

The configuration wizard enables automatic configuration of the settings that are required for the application using TREX to communicate with TREX using an HTTP or RFC connection.
