"ALTER SYSTEM FLUSH BUFFER_CACHE;"
Oracle's data buffer cache was deleted using the database command.
But then the mistake happened. ORA-01031 is the SQL Error  .
So I issued a different command:
"The following issue occurred while executing rdsadmin.rdsadmin util.flush buffer cache. Error code   in SQL: ORA-00900
Execute "exec admin.admin util.flush buffer cache;" according to the documentation. Can you explain why I can't use this command despite the fact that it indicates I can?
Does flust buffer cache have any other methods?
