These days there no statistics for our database, recently we have collected the stats for our entire application schema , but after stats the query which is used to complete in 1 min has gone to 7 min. So can somebody help why is it ?

Command Used

exec dbms_stats.gather_schema_stats ('Schema_name', cascade => TRUE);

Thanks in Advance
