dbcc enhancements

dbcc has been enhanced to improve its performance in parallel environments and to expand the way in which it detects, records, and reports errors. The dbcc checkstorage command allows you to check a database that is in use, with little or no impact on performance. It stores the results of the check in the dbccdb database. When the check is complete, you can use the new dbcc stored procedures to generate reports based on the data that is collected.
