Our Shameless Marketing Moment
Too many organizations around the globe suffer from HARDWARE ADDICTION. Hardware upgrades are an extremely costly bandage, often ineffective, and frequently unnecessary. At one customer site, we reduced the number of pSeries CPUs required from 56 down to 28 in 45 minutes.
Database vendors claim that their databases are capable of self tuning, but watch this episode and you will see the full truths revealed. If your "automatically tuned" database fails to meet performance expectations, your same vendor will be delighted to sell you upgraded hardware or On Demand CPUs.
Further validating that databases are not capable of achieving performance optimization at minimal cost on their own, the database vendors also sell extra cost performance analysis tools. One of DBI's customers reported to DBI that said database vendor's performance tool took over a month to install, required several calls to Germany, frequently crashed, and added some 20% overhead to their system. Ah yes --- well, that is to be expected --- these nice folks are in the hardware business and they license their database and tools according to the installed processor capacity.
