Re: Automate defragmentation

That works, run load sim in production... Wasn't that MEC 2002, in Aneheim,
HP presenter ... don't recall the name. It's still a client side solution.
Wasn't leakyapp.exe part of the platform sdk or ddk? You could launch and
kill leakyapp on a scheduled bases; that's a server side solution.

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.

You forgot one.

4. Download the Jetstress and Load Generator tools from
http://technet.microsoft.com/en-us/exchange/2007/bb330849.aspx and run
them continually. I'm sure you can find a way to script them...
