Re: [UrbanSim-Users] MySql configuration

Hi, we've been doing a similar thing here in Austin, where we've been creating a
small subset of the region, (using the Eugene files for some of the data we may
be 'missing'). We got a similar message. The problem is that there isn't enough
office space for at least one of your sectors of employment. The trick we've
used so far to get around this was to increase the square footage of our
buildings (I think I made it triple the normal size). This apparently has to be
done in both the buildings table and the gridcells table - an interesting
question is whether the change only needed to be made in one of the tables. A
different, but similar way of solving this problem (which we didn't use, but
you're welcome to try) would be to reduce the square footage needed per job in
the relevant fields in the gridcells table.

Good luck,

Larry H-C
