Huh? I used
28,000,000 people
7000 miles
5000 feet/mile
= 0.8 ft = 1 ft/person
One!! I thought it was 10, must of dropped a zero somewhere.
I tell my developers when sizing tables an error of 2 or 4 times
is okay but an order of magnitude is a bit much. Thanks for
the correction.
More math, Steve has asked how many mile I put on my bicycle
while in the valley:
11 months
10 days/month (I telecommuted the other 2 weeks)
8 miles/day
= 880 miles
add the zero I dropped earlier
= 8800 miles
I thinks thats why it didn't work out in the valley for me.
Only a four mile commute, I just didn't have the right attitude :)
You're right Steve, it is still a little cool to be riding in
Calgary right now. (though there are some crazies who ride all
winter, the thought of it being 30 below, on a bike makes me
shiver as I sit here, Brrrrr). March in the valley is
very similar to May in Calgary. In Calgary I usually bike
from the middle of April to the middle of October. My house
is six miles from downtown so I usually put on about 1200
(oh, add the zero, 12000) miles a year there.
Beers!! I found a place that served Humboldt Red Pale Ale.
Any companies in Humboldt county looking for a DBA? I
patronized the place (The Fish Market) until the keg ran out,
notice I didn't mention this until the keg ran out, and then
they told me they were not going to order another one. The
nerve of some people. Really good beer, I was impressed.
OEM, after reading about the trials and tribulations of people
trying to install OEM, why are people wasting their time and
money running a product that requires you to take a massive
security risk by running Intelligent agent.
I have a set of monitoring scripts (email me offline if
you want a copy, do not ask for support if, they do not work
on your db, you will learn more if you fix them yourself)
that I install at every site. Within 15 minutes I have realtime
text reports that cover everything from invalid objects,
snapshot refreshes, extents, I/O memory. latches , config
parameters.... ( about 6 pages of data).
Create a reporting schema, install perl DBI, (not on the db
server, on a client somewhere) gnu-plot or a similar graphing
package (anyone know a good perl one?) and within a week
you have graphical historical reports.
It's free and you have increased your skills.
As for detecting outages, here is a short ksh script that connects to
the db as normal user. If the connect fails, do a network ping.
This is to determine which type of admin gets paged.
It used to do a tnsping before the ping but since the DBA has
to fix it anyways that was redundant. Far more relieable than OEM.
And yes I know it is lousy code, but look at my math, what do you
expect.

The problem with point and click GUI's is that they isolate the DBA
from the detailed sql that is needed to really MANAGE Oracle.
IMHO
