It gives Oracle info about how it should get the data (use index, full scan) according to the number of lines in the table and the setup of the optimizer (cost based, rule based). Be carefull that old statistics could conduct oracle to a bad choice.

You can also detect any chained rows in your oracle blocks with this command.

AFAIK, it does not flush anything from the memory.

Hope this helps
