Can a DBCC checkdb be run on a resource database?
Because the Resource database is modifiable only in single-user mode, the DBCC CHECKDB command cannot be run on it directly. However, when DBCC CHECKDB is executed against the master database, a second CHECKDB is also run internally on the Resource database.
What causes DBCC checkdb to run faster than SQL Server?
Causes DBCC CHECKDB to obtain locks instead of using an internal database snapshot. This includes a short-term exclusive (X) lock on the database. TABLOCK will cause DBCC CHECKDB to run faster on a database under heavy load, but decreases the concurrency available on the database while DBCC CHECKDB is running.
How are error messages displayed in DBCC checkdb?
Displays all reported errors per object. All error messages are displayed by default. Specifying or omitting this option has no effect. Error messages are sorted by object ID, except for those messages generated from tempdb database.
What happens when checkdb is executed against SQL Server?
