You use the TREX admin tool (standalone) to add a new host (server or server blade) to your TREX landscape.
Procedure
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. This installation guide is located on SAP Service Marketplace at service.sap.com/installNW70.
For a distributed TREX installation with server blades, use the cloneInst.py script to generate a new TREX instance on the server blade.
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.
