Gathering statistics local / remote 11gR2 database

Hi,

After upgrade to 11g of a local database DB1 and a remote database DB2 , I have to gather dictionary + system + fixed tables statistics .

My application runs in DB1 use dblink to acceed remote database DB2.

On which database I have to gather statistics like:

-- Dictionary statistics

execute dbms_stats.gather_dictionary_stats();

execute dbms_stats.gather_system_stats('START');

-- System statistics

execute dbms_stats.gather_system_stats('STOP');

-- Fixed tables
execute dbms_stats.gather_fixed_objects_stats;

Best regards.
