If you look at the event 1221 it tells you how much white (free) space there
is in that database.

Thank you all for your response!

 

In fact database maintenance is enabled and there are 1221 events, I did not
search it properly.  To calculate the amount of space occupied by the users
in a particular database I summed up each mailbox size and it is 8GB but the
database is 28 GB. 

 

This is a new cluster setup and I migrated user mailbox from old setup( old
is also exchange 2003 SP2), hence I expected it do away with any white
space. But the size of the database remains same. That is the reason I
wanted to know if there are any tools to first check to see that database
really requires offline defrag, this tool should run when the database is
online. 

 

Can I run ESUTIL space dump when database is online?? Is it recommended to
do so? Will this help me in taking a decision ? Please advice.

 

Regards

Praveen R

Even u can plan for DB consolidation for eliminating the white space in the
database. Procedure for doing this is as follows.

Move all the mailboxes to different store.

Dismount the store.

Rename the database to some other name.

Mount the store.

New database will get recreated.

Delete the old renamed database.

Move all the mailboxes back to the original store.

Configure database maintenance and you will start getting 1221s.

Hi,

 

Few of my exchange database is un-necessarily high, it is showing 29 GB
though it has only 200 users each, other databases are showing only 5 to 7
GB. How do I decide about running offline defrag or not on this database. I
am not even getting any 1221 events also. Because of the size of the
database my backup is taking longer. 

 

I use exchange 2003 SP2 on windows 2003 SP1. Please advice.

 

Regards

Praveen R
