Diagnosis
The delta mode was set for the selected index. In this case, after thenext rollup or change run in which new data is written to this index,the data is written to a delta index. In this way, the write processesare to some degree considerably shortened, but the read access times areincreased. The read times get worse the larger the delta index.

Procedure
Combine the delta indexes with your main index regularly in a separateprocess. To do this, schedule the process or the program "R
SDDTREX_DELTAINDEX_MERGE" .
