TREX 7.1 Features

TREX 7.1 has the following new functions:

Support for 64-bit operating systems to improve performance

TREX 7.1 supports the 64-bit operating systems Microsoft Windows Server 2003/X64 and LINUX SUSE SLES9/X86_64. By concentrating on these 64-bit operating systems, SAP was able to significantly improve the search and indexing functions provided by TREX.
Large TREX indexes with more than 2 GB working memory

Since 64-bit operating systems enable the creation of TREX indexes that require more than 2 GB of working memory, you can now index and search more comprehensive and more complex data and document sets.
Delta index in working memory for join indexes

From TREX 7.1, the TREX delta index can be kept in the working memory (like the main TREX index). This speeds up the integration of the delta index in the main index and means that integration can take place without search downtime. In addition, the delta index is now also available for join/compound indexes.

Note

Implementation Considerations

During installation of SAP NetWeaver, you can install TREX as a stand-alone engine, to make its functions available as part of an SAP NetWeaver IT scenario for the application in question.
Check the SAP NetWeaver master guide and the master guide of the application using TREX to see which TREX version is used for which scenario.

Note
For more information on the SAP NetWeaver master guide, see SAP Service Marketplace at service.sap.com/nw70doc.
