yet. I have seen cases in other situations where bulk deletes make a
volume fairly unresponsive, but that may have been specific to the raid/drive
configuration on that server? I run nightly spatial translations and
database backups on the same drive array on one of my servers. The drive
became fragmented extremely rapidly, affecting performance. I ended up
having to purchase/install Diskeeper to maintain acceptable performance on
that server.</FONT></SPAN></DIV>

<DIV dir=ltr><FONT face=Arial size=2>You think there is that much of a problem
with fragmentation? We do a similar process now with picture/data
files where we delete them. We do this because of the older system we are
migrating from. I was hoping that I would not have to do this with
Enterprise, but it's not that big of a deal if I can just automate
it. I don't see an IO hit or fragmentation problem now.

the current functionality of base layers is that they don't update
themselves based on an underlying data change regardless of the source data
type. This would be up to you to delete the images from your TileCache
directory to force them to rebuild the next time somebody viewed that map
area.</SPAN></FONT></P>

anyone that has tested it already) know if I use Oracle Spatial data for my
base layers, will Mapguide Enterprise know about the changes and update the
tiles accordingly? I’m in the process of testing this and just
wanted to know if anyone has had any experience with it.</SPAN></FONT></P>
