That sounds massive. Have you got software inventory turned on and are you collecting files or something? I've worked on several 5000 seat sites and the DB is less than 10GB.

As for maintaining the DB, you need to look at several SQL scripts by Ola Hallengren. His scripts are now the de facto way to look after SQL:


The other thing to look at is whether your DB is set to Full or SImple mode. You don't want full. It is only meant for databases where you would want/need to replay actions, like finance. CM does not need that and yes, it bloats the logs a lot. I had to cleanup the mess from a predecessor for SCOM and the logs went from 20GB to 2GB.

only default settings are enabled and software inventory will capture the exe file information from computers but it does not capture the entire files.  When I click on shrink I am getting 43% free space. can I shrink sccm database?

OK, I forgot to ask - how many computers does CM manage? Also are you just talking about the Transaction Log? If so, as I said CM doesn't want it, doesn't need it. At all.

Many DBA's mistakingly think that an SMS/SCCM database needs to be handled like a transactional database, which it is not. Database recovery mode should be set to simple... in other words, we do not want the transaction log file for anything!

Ref: from MS tech answers

So the answer is yes you can BUT do a full SQL backup first.
then do a full CM backup.

Then check/validate both backups are GOOD backups by restoring to another box.

Note: I've used shrink personally on the SCOM transaction log and it worked perfectly but never on SCCM. I believe neither make full use of it, so it's just there to satisfy SQL.

I would get a second opinion if I were you, rather relying on my word alone :).

1. I have 1000 clients
2. I am talking about CM database not the transaction log
3. Recovery Model is simple

OK - 190GB still sounds big to me for 10K machines.

If you're talking about the CM I would definitely get a second opinion.
