Alex:

No, the rbo does not support bitmap indexes or any other Oracle8 or greater feature (such as partitioning, etc.). To use these features, you must set optimizer_mode to CHOOSE, FIRST_ROWS or ALL_ROWS, which will invoke the cbo.

Anybody knows whether rule based optimizer can use bitmap indexes?
