Procedure documentation Specifying the Address of the TREX Name Server Locate the document in its SAP Library structure

Use

The TREX Java client needs to know the address of the TREX name server in order to communicate with the TREX servers. The following procedure describes how you determine the address and enter it into the configuration settings for the TREX Java client.

Note

The TREX Java client communicates with the TREX server by HTTP and TCP/IP. Make sure that the TCP port that the name server uses is open.

Procedure

...

       1.      You can determine the address of the TREX name server in two ways:

¡        On the TREX host, open the configuration file <TREX_DIR>/<host_name>/sapprofile.ini. Determine the name server port that is entered in the parameter TREX/NameServer/Port.

¡        Start the TREX admin tool (see Starting the TREX Admin Tool) and determine the address of the name server using Landscape Tree ®  topology ® globals ® all_masters.

       2.      Use the user <j2eeadm> to log onto the host on which the J2EE Engine is running.

       3.      Start the SAP J2EE Engine Visual Administrator Tool and log on to the J2EE Engine.

For more information about using this tool, see the SAP Library at the Internet address help.sap.com ® Documentation ® SAP NetWeaver

       4.      Click Cluster and navigate to Services ® TREX Service.

       5.      Enter the address of the TREX name server into the parameter nameserver.address.

tcpip://<host_name_of_trex_host>:<name_server_port>

You enter only the host name or the host name and the domain depending on your network environment.

Example

tcpip://mytrexhost:34801 or tcpip://mytrexhost.mydomain:34801

Caution

The address of the TREX name server must be configured for all server processes of the cluster. Otherwise the connection between the J2EE Engine and TREX cannot be established.

       6.      Save your changes and confirm the restart of the service.
