Small tip: moving statistics

Here there is a small experiment. A colleague of mine stated that loading statistics through impdp is a horrible thing in comparison to simple export and import with the dbms_stats package.

begin
-- on the source
dbms_stats.create_stat_table('','','');
dbms_stats.export_database_stats('','','');

-- on the target
-- first impdp stats table
dbms_stats.import_database_stats('','','');
end;
/

I give it a try and I am very glad of the results. The main problem with exporting and importing the statistics with the Data Pump is the operation duration - using dbms_stats will take a fraction of time spent on the export and import with the Data Pump technology.
