与statistics相关的数据库参数
SQL> show parameter statistics NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ optimizer_use_pending_statistics boolean FALSE statistics_level string TYPICAL timed_os_statistics integer 0 timed_statistics boolean TRUE SQL>
statistics_level->{ALL | TYPICAL | BASE}
与snapshot相关的参数
snapshot level
- >=0
- >=5
- >=6
- >=7
- >=10
snapshot parameter table(在执行snapshot时，如果不输入任何参数，就会读这张表中的参数)

与instance相关的配置参数
相关的配置文件sprepcon.sql 实际上instance report 与 sql report相关的报表所使用的参数均为sprepcon.sql
define num_days = '';
参数解读:假如为''，表示列出所有snapshot；假如设置为10，就表示列出最近10天的snapshot信息.
与sql report相关的参数
相关的配置文件sprepcon.sql
输出sql report可以根据sql的hash value来生成.
maintenance
在众多的snapshot中，那些被有用的，成为baseline.
purge只会把那些没有标记为baseline的snapshot给删除掉.
- make_baseline & clear_baseline
- purge snapshot except baseline
- truncate all tables with perfstat schema
- drop perfstat schema

truncate all tables with perfstat schema
truncate all tables with perfstat schema使用到的是sptrunc.sql脚本

如何导入perfstat用户？
前提：创建好用户，创建好权限.
创建用户的话，我们使用oracle提供好的spcusr.sql脚本.但是此脚本需要做修改.

随笔:
oracle在执行查询的时候，其主要依据就是optimizer statistics 数据，所以适当的频率更新schema的optimizer statistics数据对于提高sql查询语句的性能是非常有帮助的.
