SQL Server is a relational database management system (RDBMS) by Microsoft that is designed for the enterprise environment. It has got two primary query languages, T-SQL and ANSISQL. It provides you the flexibility to access your database from anywhere, be it from a data center, desktop, or from a mobile device. It also provides combined services to query, search, synchronize, report, and analyze the database records. However, at times it may happen that the SQL Server is unable to run. It may be possible that the master database has gone corrupt. This can be possible because of various reasons such as virus infections, human errors, power outages or abrupt system shutdown while SQL Server was open. In such cases, you should replace the corrupted database with its updated backup. However, if the backup is not updated then you should use a third-party SQL Database Recovery software to recover SQL database.
Consider a scenario wherein you have MS SQL Server 2008 installed on your system. When you log onto the SQL Server, you are unable to do so. An error message is displayed, that is:
“Cannot recover the master database. SQL Server is unable to run. Restore master from a full backup, repair it, or rebuild it. For more information about how to rebuild the master database, see SQL Server Books Online.”
Cause:
The cause of the mentioned error message is that the SQL Server is unable to start the master database. If the master or tempdb database cannot be mounted, SQL Server cannot run. It is quite possible that the master database has gone corrupt because of various aforementioned reasons.
Resolution:
To resolve this issue, you should, first of all, check whether there is an updated backup of the master database. If yes, then you should replace it with the corrupted database. However, if the database is not updated then you should use a third-party SQL database recovery software to perform SQL Recovery of the corrupted database. Such read-only tools are able to recover SQL databases using fast yet sophisticated scanning algorithms.
SQL Database Recovery is an SQL Server recovery tool that enables you to perform SQL database recovery of the corrupted databases. It is able to repair various database components such as tables, defaults, stored procedures, triggers, views, and rules. It can also repair user-defined data types and functions and also database constraints such as primary key, foreign key, unique key, and check. It is compatible with Windows 7, Vista, Server 2003, XP, and 2000.
