Re: Performance and Number of Databases

[Ed Cunningham<ecnghm@xxxxxxxxxxxxx>]

Niether choice of consolidation or split is a good way to go. You must make 
up your mind now. 

I haven't the knowledge of the sizes of the db verses the power of your 
equipment to help you make a decision based on that info, but I do have 
this experience:  It all boils down to just how simular each site is and 
how much consolidation of info is required.  If each site can stand on it's 
own and G/L consolidations aren't necessary or can be accomplished in a 
simple way than separate is better.  Any sharing of data or reporting or 
financial sharing or business decision processes that are common require 
you to beef-up you resources at a center location with one db.

Subject:        Performance and Number of Databases





My company is preparing to implement BPCS in an AS/400 environment.  We
have several manufacturing plants scattered across the US.  Currently, we
have a raging debate over whether to configure a single large database or
multiple databases by plant.  Each choice has trade-offs but so far,
nothing has surfaced that has been sufficiently compelling to tip the
scales one way or the other.

Does anybody have any sage wisdom on this?  What might be the performance
implications of accessing a single large DB versus a multiple DB scenario?
If we choose wrong, would it be easier to consolidate multiple DB's at a
later date or easier to break up a single DB into smaller ones?

Thanks in advance,

       ......Eric
