SAP Basis Tech Supports

Symptom

You find that indexing in SAP NetWeaver BW Accelerator is slow and you want to check whether the write calls to the BWA filer are slow.
Other terms

BIA, BWA, Accelerator, performance, rollup, changerun, filer, initial filling
Reason and Prerequisites

You find that BWA indexing calls are taking a long time to execute and you want to check whether the write calls to the BWA filer are responsible for the slow execution.
Solution

Raise trace level for BWA components “indexoptperf” and “AttrTempFilePerf” to “DEBUG”.
To raise a trace level, you can use the TREX standalone admin tool or the SAP transaction TREXADMIN: in view “Trace” press button “Levels …” and choose Service “Indexserver”.
The new trace level is activated when you save the change. You do not need to restart the TREX index server.
Note:You should only raise the trace level if you are asked to do so by an SAP support engineer.
