有了从监控任务中收集的缓冲池运行时统计数据,您就可以知道是否任何性能获益都可以从缓冲池调优实现。
With the buffer pool runtime statistics gathered from the monitoring tasks, you can see whether any performance gain can be achieved from buffer pool tuning.
您将发现,与用于关系数据和索引的已有的计数器相对应,DB 2 9为XML数据提供了新的缓冲池快照监视器元素。
You will find that DB2 9 offers new buffer pool snapshot monitor elements for XML data that match the existing counters for relational data and indexes.
问题查询:这些查询只返回超过重要性能计数器阈值的行,例如缓冲池命中率不到90%的行。
Problem queries: These queries return only rows that exceed thresholds for important performance counters, for example, rows with buffer pool hit ratio lower than 90%.
