Re: Automate defragmentation

Unless you recently and permanently removed a large amount of mail, it's
pointless. The whitespace will come back in that a certain amount of
whitespace is normal. If you remove it in this case, you will degrade the
performance of your exchange server. After an offline defrag Exchange has
to allocate more disk space because you spent hours offline removing the
whitespace that's used in normal operations. Exchange also has to spend
cycles rebuilding the indexes that the offline defrag cleared. So, let me
get this straight; you want to know how to degrade the performance of your
exchange server on a regular scheduled basis....

OK, let's see,

1. Every night you could pull a drive from your RAID array and let it
rebuild - wait that involves a manual step.
2. You could intentionally detune memory by putting a very low value for
jet databasebuffers that is not of the proper increment. - wait, you only do
that once.
3. You could load desktop search engines on all the desktops in your
environment and schedule them to do a crawl at 0:800 AM and one hour
intervals thereafter - it's a client side solution, but I believe it meets
your criteria.


There you go.

OFFline defrag- OFFline defrag -it's the only way to get back disk
space/shrink db size. online does not shrink the dbs.
