I am about to approve this comment out on my blog from one of my favorite DBA
God's:
"Yep, like Cary is saying " 90% of performance tuning is politics". I am
paraphrasing. Don't hold me to the exact quote or percentage.I don't understand
"priorities for the business may not be the same as a priority for the
DBAâ??s". If it is not a priority for the business why should it be a priority
for the DBA? Politics work both ways. You are skating close to CTD. If nobody
else cares about performance why should you?"
I respect his opinion and it did get me thinking about where performance tuning
falls in the priority of tasks for most database environments. Â I commonly am
brought into places that have a history of bringing code/designs to production
in a short time-span, business requirements and/or revenue demanding that
everything works being more important than it working efficiently or performing
well, then my job is to go in and correct this "little oversight". Â
I honestly don't think it's intentional by the business to move poor performing
or code that will only be able to sustain the business for a short period of
time into production, it's just due to the demands of the business for many
companies. Â This does, however, make performance tuning a lesser priority in
many environments, (and keeps me in demand and well employed... :))
As I specialize in this area, I now question the kind DBA's on the list to see
if you also find performance tuning a lesser priority in the environments
you've worked in. Â I'm also curious what kind of environment it is, (private
sector, retail, banking, government, etc..) Â Just like disaster recovery and
other tasks that DBA's may put a higher priority on, the business, as it does
not always directly correspond to revenue, does not view as part of the goal...
Please feel free to email me directly if you wish to remain anonymous..
