Think of any utility suite as a very sophisticated tool kit. You will never
use all of the tools, even if you want too. What is of interest is which of
the tools you will use. You need to get this point to management as soon as
possible or they will make what is simply a financial decision, because
everything else is equal and the "vendor" has told them so.
I am aware of a friend who was told that he had to accept the deal made
because it was "made." He demonstrated that the "new" vendor's utilities
could not complete in 24 hours work that needed to be turned around
overnight. Several of these overnight jobs had to be canceled because they
took days and no end was insight. The company ended up paying for both
suites because the decision was made without technical input.
Set up some reasonable examples and have competing vendors prove that they
can do the work in the time allotted. Vendors play games with CPU time, but
have difficulty fudging elapsed time. The business requirements should be
the telling factor. Saving money and going out of business are not
acceptable to almost anyone but the vendor cashing the first check.

Subject: Re: [DB2-L] BMC vs IBM Utility Benchmarks....revisited
Phil hits it right on the head here.
Results will vary at every installation, and there are too many variables
for anyone else's benchmark numbers to bear relevance to your environment.
Since these queries often originate from some bean counter trying to
$1.98...., there is much more that should be considered than just money.
It should be more about features, ease of use, and making the DBA staff more
If somebody is thinking about conversion, that "somebody" should also factor
in the people and machine time cost of conversion.
For large installations, this can easily be a 7 figure cost...
