Hello All,

It should include all as you said , but since I do not belong to a capacity
planning group in my shop , I mostly concentrate on the DB growth . I have
taken Sales as business object to correlate with the DB size . I think in
our case both of them are directly proportional. ( Business objects may vary
from shop to shop )

first step I have done is calculating the : Growth factor = avg. History Db
growth / avg Hist Sales growth

Second Step : identifying the Sales projection for the next fiscal year (
Ie. I have to get sales growth percentage from the business team , for
example 15% and multiply with sales history, for each week I guess.)

3rd step: Now I have sales projection and growth Factor , and can the
projected DB growth .


Well The above is the thing I am working on by having some queries to get
the data from the DB. Also I have to automate the whole process .

I would like to know how this Capacity planning followed in your shop.
What's your answer when your group manager asks how much disk we need for
holiday prep ?? Like this we can have many questions. I know somebody is
having a better approach getting followed . Would appreciate if you share
with us.

or somebody can better help me in """identifying """ the Q? from managers
!!!!

Thank YOU all for your replies
Madhu

Check the link Kirti has posted (orapub).

Is capacity planning only on the database size ?
In my mind it also includes :
   Transaction description (online and batch)
   Transaction frequency (online and batch)
   Transaction window 
   Networking requirements
   Number of users (all and concurrent)
   Overall disk space (inside and outside the
database)
   Availability
