problem with axes limits - reaching precision limits?

Post by Laurent Gi » Fri, 20 Aug 2004 06:16:57


Hi,

I am trying to set tight limits on the x axis of a plot for two
points whose X coordinates are:

x1 = 731889.497534767
x2 = 731889.497557916

The problem is, Matlab does not let me set the 'xlim' property to [x1
x2] for tight limits, but rather uses a wider interval. If I use
relative coordinates (i.e. x2 = x2-x1, and x1 = 0), then it works
fine.
Am I already reaching the precision limits of floating point
representation, or is it a problem with the plotting function?

This behavior can easily be reproduced by the small code below, which
plot two small numbers (with tight axis), and then plot the same
numbers offsetted by 1e6 without being able to set tight axis:

x1 = 0;
x2 = 5e-6;
figure;
plot([x1 x2], [1 2]);
set(gca, 'xlim', [x1 x2]);
figure;
plot([x1 x2]+1e6, [1 2]);
set(gca, 'xlim', [x1 x2]+1e6);
 
 
 

1. Quota limit reached, but folder size is under limit

2. Reaching max limit on Excahgne DB (16gb SBS limit)

Yesterday we surpassed the 16gb limit on our SBS 2000 Exchange db. I had
been monitoring the db size from time to time but did not realize I had to
add the priv1.edb and priv1.stm together to come up with the actual db size
(stupid me).

Anyway, our current sizes are priv1.edb = 16, 661,832 and priv1.stm is
3,162,120.

I went through the process of adding the registry entry to get an extra gig
for the store and then remounted the store and it worked just fine.
(KB828070 - option#2) I immediately got users to begin deleting /archiving
their email. However, even after online defrag ran, the file sizes are still
the same. Will this not change at all until I run the offline defarag
utility ("eseutil")

Also, since we have cleaned out a lot of mail items (over 2gb) , will new
emails etc.. use that free space that has been created (overwriting email
marked for deletion) or will the database file size continue to grow until
the offline defrag is performed? If it just continues to grow, then we could
also hit the 17gb limit as well! What on earth would we do if the 17gb
barrier is reached?? Is there any further way to gain add'l space in that
case???

Is there a way in Exchange that you can have it notify an administrator if
the total DB size is within a set amount of reaching the max db size??

Thanks, Brad
