RE: bitmap conversion on a index that is not bitmapped ???

 Stephan,

 That is correct. The old behavior is not what I want. I have rebuilt and reanalyzed, deleted stats - tried all sorts of combinations and I cannot get it to use the bitmapped access as it once did. Again - these are not bitmapped indexes to begin with.

... Unfortunately the old behaviour seems to be the bad one. I guess that the solution would rather be to rebuild indexes on a regular basis ...
