|Subject: ||predicating database behaviour|
As port of an attempt to reduce the amount of manual work need to
administer our databases, I am considerring building some statistical
routines to help predict database behaviour.
I have aprocess which, on a weekly basis, stores the size of various
databse elements (for those who know ADABAS: number of records, number of
extentes (DS/UI/NI), DS size etc.). I also have data about buffer usage etc.
What I want:
* Predict the growth of databases (let's say I'd like to predcit for 3
months in advance)
* Discover erratic behaviour (based on past experience)
* Discover relationshpis between differnet databases (or files).
Anyone doing this kind of thing? If so, I'd be happy to hear your ideas.
If someone can show me actual result/code I'd be verey glad.
Any practical solutions, pointers to methods (statistical or otherwise),
is also welcome.
If/when the the project succeeds - I'll try to publish (possibly on the
net). Hopefully the results will be good enough to be reused by others.
