生成Statspack报告时候发现Snap Id为”#####”

Instances in this Statspack schema

Enter value for dbid: 631690435
Using 631690435 for database Id
Enter value for inst_num: 1

Specify the Begin and End Snapshot Ids
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Enter value for begin_snap:

因为没有办法定位到Snap Id,所以暂时无法准确的输入对应值,当然可以通过如下sql查询相应的Snap Id

select SNAP_ID,to_char(SNAP_TIME,'yyyy-mm-dd hh24:mi:ss') SNAP_TIME 
from STATS$SNAPSHOT order by SNAP_ID; 

虽然可以通过这个方面来曲线解决这个问题,但是还有比较完善一点的解决方法,我们阅读spcreate.sql相关脚本,修改相关程序来实现

--通过spcreate.sql发现
spcreate.sql调用@@sprepins

--编辑sprepins.sql
column instart_fmt noprint;
column inst_name   format a12  heading 'Instance';
column db_name     format a12  heading 'DB Name';
column snap_id     format 9990 heading 'Snap|Id'; 
-->(修改为)column snap_id     format 999990 heading 'Snap|Id';
column snapdat     format a17  heading 'Snap Started' just c;
column lvl         format 99   heading 'Snap|Level';
column commnt      format a22  heading 'Comment';

再次生成sp报告

SQL> @?/rdbms/admin/sprepins.sql
