The tempdb database is one of the system databases in SQL Server. It is used to store the temporary tables, table variables, etc. The tempdb is recreated every time SQL Server is started. This way, the system always starts with a fresh copy of the tempdb database. However, sometimes the tempdb gets corrupt because of various issues such as power outages, virus infections, human errors, abrupt system shutdown, etc. In such cases, you should take appropriate corrective measures to resolve the issue. However, if you are not able to do so then you should use a third-party MS SQL repair tool to repair SQL database. Consider a scenario wherein you are performing allocation checks on the tempdb database. But the process terminates abruptly and an error message is displayed, that is: “Database tempdb allocation errors prevent further CHECKNAME processing.” Cause:
The most possible reason for such behavior is that there were allocation errors in the tempdb database. And as the tempdb database cannot be taken offline, the operation is cancelled and, hence, the error message is displayed. Resolution:
To resolve this error message, there are various things that you can do. They are:
Look for hardware failure: Run hardware diagnostics and check whether the error is because of any hardware issue. You can also check the error logs or swap the hardware components to ascertain this point.
Restore from backup: Replace the corrupted database with its clean and updated backup.
Use DBCC CHECKDB: Use the DBCC CHECKDB command without any repair clause to know the extent of corruption. After determining it, you should run DBCC CHECKDB again with the recommended repair clause. However, if you are unable to sort the issue even after using the aforementioned methods then you should use a third-party SQL repair software to repair SQL database. Such read-only tools are able to repair the corrupted databases without overwriting the original data. SQL Database Recovery Software is an MS SQL repair tool that enables you to repair SQL database. It is capable of performing MDF repair of corrupted SQL databases created in SQL Server 2000, 2005, and 2008.
