How often should VRDB be run? Each time a new program is installed to update the database?
No, there is no reason for that.
Can you search the 'Users FAQ' link bellow in my signature.
There is an explanation about VRDB.
In 'Settings', there is the parameters to configure VRDB running.
Hope this help
