Thread: pg_autoconfig.pl

Heya,

Sorry for no updates on the old pg_autoconfig script thing, been rather
busy at work the last week or two :-( but i suppose it pays the bills. I
do have a few days off work now so I can spend some time on finishing
the first version off. The latest version can be found at

Josh have you managed to put together the rest of the calculations yet?


Thanks,


Nick

Nick,

Given that I spent most of November working on the PR for the 7.4 release,
I've just started to think about it.  As you can see, I'm thinking about
dovetailing pg_avd and pg_autoconf.

The difficult thing is to figure out settings for "bad" hardware setups.  Like
a 5GB database on a PIII500 + 256mb running 4 other pieces of major software
(I've acctually seen this).    Or a 500/minute OLTP database on a machine
with 1 fixed disk.

All the variables are going into a hash array, right?

Yep that rights.$sys is the array name. And there are loads of different
keys for the hash. I will try and get a listing out of the script sometime.
