Oracle Enterprise Manager性能图中的“配置”指标是什么意思？

Question

When looking at the OEM performance graphs what does the "Configuration" Metric indicate?

Since the term configuration is so generic, it is difficult to find meaningful results from a search. I have tried the help pages within OEM as well.

Answer 1

You can check all the wait events on this Oracle page: http://docs.oracle.com/cd/B19306_01/server.102/b14237/waitevents001.htm

Configuration

Waits caused by inadequate configuration of database or instance resources (for example, undersized log file sizes, shared pool size)

Ocurrences of log file switch, write complete waits or log buffer space are labeled "Configuration" on EM. Just click on "configuration" to see a more detailed graph about this events.

[EDIT]: An additional note... I don't remember seeing any meaningful ocurrences of "Configuration" events on any of the databases I've managed. Which either means I'm pretty good at sizing, or that it usually isn't a problem at all. I'm prone to choose the second one ;)
