Gathering statistics after upgrade to 11g

 Hi ,

After upgrade from 10g to 11g , are you agree with me gathering statistics like this :

------------------------------------------------------------------------------------------------------------------

-- This procedure gathers statistics for dictionary schemas 'SYS', 'SYSTEM' and schemas of RDBMS components.

------------------------------------------------------------------------------------------------------------------

execute dbms_stats.gather_dictionary_stats(); -- just after upgrade to 11g.

------------------------------------------------------------------------------------------------------------------

--This procedure gathers system statistics.

------------------------------------------------------------------------------------------------------------------

execute dbms_stats.gather_system_stats('START');

-- 1  hour of workload

execute dbms_stats.gather_system_stats('STOP');

------------------------------------------------------------------------------------------------------------------

--This procedure gathers statistics for all fixed objects (dynamic performance tables).

------------------------------------------------------------------------------------------------------------------

execute dbms_stats.gather_fixed_objects_stats; -- while workload

Best regards.
