Recently I've run into a few FIM 2010 installations where unfortunately there was paid no attention to the SQL Agent jobs that are created when FIM 2010 is installed.
Microsoft has put out a few good pointers with regards to these and it is well-worth while to read through these. You can find them here http://technet.microsoft.com/en-us/library/ff830030(WS.10).aspx.
The parts about temporal sets and group are very interesting and leads me my biggest wish for future versions on FIM. We do need customizable triggers that can be defined in the portal. These are needed for different tasks and it would be very nice to be able to move these away from SQL Stored Procedures and into the FIM Service instead. Especially, so that you don't have to convience your (or your customers) SQL DBA to have and maintain different schedules for these speciel FIM jobs.
Just some food for thought.
