Oracle statspack里sprepsql.sql 的用法和作用

sprepsql.sql 用于根据给定的SQL Hash 值生成SQL 报告
里面包括完整的sql和对应的执行计划
@sprepsql.sql 输入开始和结束snap_id
然后再输入sql hash value值 在输入路径和文件名 生成的报告如下:

All Optimizer Plan(s) for this Hash Value
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Shows all known Optimizer Plans for this Hash value, and the Snap Id's they
were first found in the shared pool
-> ordered by Snap Id

Plans in shared pool between Begin and End Snap Ids
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Shows the Execution Plans found in the shared pool between the begin and end
snapshots specified. The values for Rows, Bytes and Cost shown below are those
which existed at the time the first-ever snapshot captured this plan - these
values often change over time, and so may not be indicative of current values
-> Rows indicates Cardinality, PHV is Plan Hash Value
-> ordered by Plan Hash Value
