Adding a Host 

Use

You use the TREX admin tool (stand-alone) to add a new host (server or server blade) to your TREX landscape.

Procedure

...

       1.      Start TREX on the host that you want to add to your TREX system landscape.

○       Install a TREX instance on the server

If you have not yet installed a TREX instance on the host that you want to add to your TREX landscape, do so before continuing with the procedure.

For more information about the installation of TREX, see the SAP NetWeaver 7.0 Search and Classification (TREX) Single Host installation guide. The guide is located in the SAP Service Marketplace at service.sap.com/installNW70.

○       Install a TREX instance on the server blade

For a distributed TREX installation with server blades, use the cloneInst.py script to generate a new TREX instance on the server blade.

See: Activating the Configuration Clones for Server Blades

       2.      Go to the Landscape ®  Configuration window in the TREX admin tool (stand-alone).

       3.      Add the server or server blade to your TREX landscape as follows:

○       Following the installation of an additional TREX instance on a server, execute the Add host command (see Adding a Host)

○       The cloneInst.py script automatically adds the server blade to the landscape

       4.      Select the Master Index/Queue Server indicator for the host that you want to add to your TREX landscape.

       5.      Choose Check and then Deploy to save your change.

       6.      In the Landscape ® Reorg window, go to the Plan tab page.

       7.      Choose Start Reorg to start the required reorganization of your TREX landscape.

After adding a host (server or server blade) to your TREX landscape, do not simply carry out a reorganization. For performance reasons, you should completely redistribute the indexes. To do so, select the Split/Merge Index checkbox in the Landscape ® Reorg window of the TREX admin tool (stand-alone) and then start the reorganization. During this type of reorganization, the system also recalculates the number of parts of which a logical index consists.

Note that this reorganization can cause a complete reindexing process that can last as long as the initial indexing run. During this period, the system cannot perform indexing runs and searching is limited.
