oracle - computing statistics at the schema level (11g) -


this question computing statistics @ schema level (11g).where schema level statistics stored .where can retrieve details of schema level statistics?and next step after gathering statistics?

what tried far?

begin     dbms_stats.gather_schema_stats            ('staging'                ,estimate_percent => 20                 ,method_opt => 'for indexed columns size 1'                 ,block_sample => false                 ,degree => 32                 ,granularity => 'all'                 ,cascade => true); end; /

what next step after this

gathering statistics @ schema level means have stats tables in schema (and indexes, because cascade=>true). can find values querying relevant data dictionary views (user_tables, user_indexes).

what next step? considering refresh policy. best approach automate task. find out more.
