RE: System Analysis Suggestions

[lloen@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx]

As I look at your raw numbers, I don't immediately conclude you have a
bottleneck.

Nor do I conclude you have a problem serving web pages.

It might be true, you obviously know more about this, but the data you
posted up below isn't strongly supporting it.  GO PERFORM is a good
suggestion here.

That said, you're running at 87 per cent with 60 per cent DB Capability.

Those sound like a decently running system doing mostly ordinary
transaction processing to me.  Maybe the web serving is the "straw that
breaks the camel's back" but I would be inclined to spend some time
looking at your basic functionality.  For instance, how much ordinary
(non-web) processing do you do?  Within your web serving, how much time
to you spend in Data Base and on what?

You might look at activity levels.  Particularly, see if there is any
Active->Ineligible on WRKSYSSTS.  If you have a lot of those, then your
activity levels on those pools might be too low.
