Use

You can use the Reorg function to distribute the indexes in a TREX system landscape among the available hosts to optimize their memory requirements. The reorganization aims to achieve a balanced memory load and CPU load for the TREX system landscape.

A reorganization can be necessary in the following circumstances:

●      You make changes to your TREX system landscape. For example, you remove index servers or add new ones.

●      The current size of indexes does not match the initial size estimates.

 

Effects on the Dataset

During the reorganization, indexes are moved. The affected indexes cannot be updated during the reorganization. Indexing is interrupted for the duration of the reorganization.

 

Effects on System Administration

The TREX alert server contains the reorg check. When this check runs, you are automatically informed by e-mail (if configured), if TREX recommends a reorganization. Alternatively, you can check in the TREX admin tool (stand-alone) whether a reorganization is recommended. You can find the Reorg function in the Landscape: Reorg ® Summary window.

If TREX recommends a reorganization (summary = yes), you start the function by choosing Start Reorg.
