Gather_stats_job 调用dbms_stats.gather_database_stats_job_proc过程来收集statistics 的信息
Gather_stats_job 调用dbms_stats.gather_database_stats_job_proc过程来收集statistics 的信息。 该过程收集对象statistics的条件如下: (1)对象的统计信息之前没有收集过。 (2)当对象有超过10%的rows 被修改,此时对象的统计信息也称为stale statistics。 在Oracle 10g中,在查询表时,如果没有统计分析,那么会采用动态采样。[@more@]
