How to collect Statistics for A Single Partition in OSM (Doc ID 1297022.1)

Goal

1.What are all the tables that must be included in the collect statistics for a single partition? Will the following script suffice to collect the stats for a particular partition?

begin
DBMS_STATS.GATHER_TABLE_STATS(ownname=>user, tabname=>'OM_ORDER_INSTANCE', partname=>'P_000000000003100000',estimate_percent=> 10,block_sample=>true,
method_opt=>'FOR ALL INDEXED COLUMNS SIZE AUTO',granularity=>'ALL', degree => 4, cascade =>TRUE);

END;

2.What is the Oracle recommendation? Is it OK to run a collection of statistics only for one newly created partition instead for the the entire schema?

3.How often is a user required to run a collection of  statistics, and which ones must be collected?
