Microsoft SQL Server
SQL Server is Microsoft's entry to the database server market. SQL Server is very easy to manage and comes with a built in OLAP engine. It has good support for web enabled applications and other Microsft products. SQL Server only runs on the Windows platform.
When I shrink database, the system raise error 8985: Could not locate file 'databasename_dat' in sysfiles.
Does anyone has experience to solve this error...?
This typically means that you've had a device (disk drive) go offline. There is rarely any way to recover unless you can either bring the device back online or restore a backup to another disk.
