11g建议使用DBMS_STATS.AUTO_SAMPLE_SIZE，维护窗口内，尽可能按照100%完成自动采样，若100%的方式不适合，则会at least采用30%的采样比例。并且强调了11g采用了HASH算法，计算统计信息，因此几乎在所有场景下，性能都不是问题。

1. 9i中ESTIMATE_PERCENT默认100%。
2. 10g中ESTIMATE_PERCENT默认为DBMS_STATS.AUTO_SAMPLE_SIZE，一个非常非常小的数，通常会造成poor的统计信息，因此并不建议使用AUTO。
3. 11g中ESTIMATE_PERCENT默认为DBMS_STATS.AUTO_SAMPLE_SIZE，但由于其采用了一种新的HASH算法，倾向于默认100%采样，其性能要比9i和10g中更优，因此一般情况下，建议使用DBMS_STATS.AUTO_SAMPLE_SIZE，由Oracle来自主选择采样比例。

GATHER AUTO重新分析当前没有统计的对象，以及统计数据过期（变脏）的对象。注意，使用GATHER AUTO类似于组合使用GATHER STALE和GATHER EMPTY。 注意，无论GATHER STALE还是GATHER AUTO，都要求进行监视。如果执行一个alter table xxx monitoring命令，Oracle会用dba_tab_modifications视图来跟踪发生变动的表。这样一来，就确切地知道，自从上一次分析统计数据以来，发生了多少次插入、更新和删除操作。
