Configuring Queue ParametersLocate this document in the navigation structure


The queue parameters control the interaction between the queue server and the index server. In particular, they specify when the queue server triggers indexing and optimization of documents. It is important for performance reasons that you have optimum settings for the queue parameters.

When TREX creates a queue, it uses the default settings for the queue parameters. Depending on the document sets that you have to index initially and on the type of documents you index, you may have to change the default settings.


The default settings that TREX uses for new queues are defined in the configuration file TREXQueueServer.ini. You can change the default settings. However, you should only make changes to configuration files after consulting SAP support or with a consultant.


You have already created indexes.


You can change the queue parameters for existing queues as follows:

Tool Path

TREX admin tool

Queue Admin → Queue Parameters

TREX monitor in the portal

System Administration → Monitoring → Knowledge Management → TREX Monitor → Edit Queue Parameters

TREX Admin Tool in the SAP System

Transaction TREXADMIN → Queue Admin → Set Queue Parameters
