快照时间是：9：40分
其中APP中的语句信息如下：
Statement type = Dynamic SQL Statement
Statement = Fetch
Section number = 1
Application creator = NULLID
Package name = SYSSN100
Consistency Token =
Package Version ID =
Cursor name = SQL_CURSN100C1
Statement database partition number = 0
Statement start timestamp = 03/02/2015 09:09:09.923204 【注意这里，快照时间是9：40】
Statement stop timestamp =
Elapsed time of last completed stmt(sec.ms)= 0.000022
Total Statement user CPU time = 25.329957 【注意这里，为什么这个时间这么小？】
Total Statement system CPU time = 0.000000
SQL compiler cost estimate in timerons = 849507 【这个这么高，有没有影响呢？】
SQL compiler cardinality estimate = 1
Degree of parallelism requested = 1
Number of agents working on statement = 1
Number of subagents created for statement = 1
Statement sorts = 0
Total sort time = 0
Sort overflows = 0
Rows read = 74208

Blocking cursor = YES
Dynamic SQL statement text:
select count(1) 总行数,count(1) 【完全语句就不方便贴这了】
当时整个系统CPU使用率比较高（90%），已确认CPU使用率高是由DB2引的，这个是其中一个正在执行APP的快照。
