However bitmap indexes are 7.3+ feature - why I asked. Alex Hillman -----Original Message----- Sent: Wednesday, September 12, 2001 1:50 PM To: Multiple recipients of list ORACLE-L 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. Jon Walthour -----Original Message----- Sent: Wednesday, September 12, 2001 1:05 PM To: Multiple recipients of list ORACLE-L Anybody knows whether rule based optimizer can use bitmap indexes?
