You might want to take a look at the docs: http://download.oracle.com/docs/cd/B10500_01/server.920/a96533/statspac.htm#21708
Note:
It is not correct to specify begin and end snapshots where the begin snapshot and end snapshot were taken from different instance startups. In other words, the instance must not have been shutdown between the times that the begin and end snapshots were taken.
At the first part of the report the database id is given. Do a select * from STATS$DATABASE_INSTANCE and verify that the DBID present matches the database/instance you are attempting to run the reprot upon. The report should be ran from the same instance in which the snapshots were taken.
