Gather Schema Statistics from front-end

Sometimes , after continuous updating,inserting or deleting of data by users(Functional,technical
or End users), it becomes necessary to gather statistics as the performance of database becomes slow.
This can be done by simply submitting a request from Front-End Forms service…which substantially improves the performance of the Application and Database.

GATHER SCHEMA STATS from Back-end
Use the following command to gather schema statistics:
exec fnd_stats.gather_schema_statistics(‘ONT’) < For a specific schema >
exec fnd_stats.gather_schema_statistics(‘ALL’) < For all schemas >
Use the following command for gathering statistics on a temporary table
(ie: temporary tablename = TEMP_tmp in schema ABC):
exec fnd_stats.gather_table_stats(‘ABC’,'TEMP_tmp’);
