Execute the following SQL commands if you are using MSDE or if you prefer to use SQL commands to prevent db_ControlManager.mdf and db_ControlManager.ldf from occupying excessive disk space.
To shrink db_ControlManager.mdf and db_ControlManager.ldf, execute these SQL commands using a SQL query tool:
Alter Database db_controlManager set recovery FULL
Backup log db_controlManager with truncate_only
DBCC shrinkDatabase(db_controlManager)
The 3rd command might take longer depending on the size of the database.
EXEC sp_dboption 'db_ControlManager', 'trunc. log on chkpt.', 'TRUE'
Alter Database db_controlManager set recovery simple
Alter Database db_controlManager set auto_shrink on
