Set variables in .omnirc file

Hello,

i´ve got a problem with one backup in my dp 9.01 environment.

The disk agent need more than 120 minutes to finish, so the backup runs into timeout.

[Normal] From: VBDA@CLIENT "BACKUP"  Time: 03.09.2014 09:46:19
    STARTING Disk Agent for CLIENT "BACKUP".

[Major] From: BSM@CLIENT "CLIENT"  Time: 03.09.2014 11:46:31
[61:1002]      The VBDA named "BACKUP" on host CLIENT
    reached its inactivity timeout of 7200 seconds.
    The agent on host will be shutdown.

So i have to set the "SmDaIdleTimeout" variable but i dont want that in the globals file. I want it especially for this client. So i have to add this variable into the .omnirc file right?

I did that, but it doesent work.

Anything wrong with this?
