If there are no growing cost SQL queries in the snapshot, analyze the access plan to see which can be amended based on the accumulated data.
如果在快照中没有成本增加的SQL查询,可以分析访问计划,以查看可以根据累积的数据进行哪些修改。
In fact, a good plan survives being amended, because a good plan is grounded in principles of behavior rather than mechanizations.
事实上,好的计划幸免于难的原因是他们在如何改变的行动准则方面打好了基础,而不是机械化的执行。
If not, analyze the access plan (for example, using DB2 Explain utilities) to see which can be amended.
如果不是这样,可以分析访问计划(例如,使用DB 2 Explain实用工具)以了解可以修改其中的哪些内容。
