Sometimes, Database Administrators – DBAs, encounter a problem which usually is not common, though the chances of its sudden appearance are positive – the problem we’re addressing here is Suspect Mode.
In rare situations, database administrators find that the SQL Database has become inaccessible and marked with the word Suspect.
In this article, we’ll discuss regarding the database suspect mode situation and things like what the consequences will be if you encounter the same and will walk you through some tips to recover SQL Database from suspect mode.
Before we start, let us see what happens when the SQL Server marks the database as Suspect?
Whenever a database receives the Suspect stamp from the SQL Server, it turns inaccessible and reflects the risk of data loss, straight.
In other fine words, because of the damaged primary file group, the database gets marked as Suspect, as it becomes inaccessible during the startup of SQL Server.
There lay many reasons that can lead to the same scenario, as each time why it happened the reason behind may vary.
Below are few arguments from many that state why the SQL Server marks the database as Suspect:
The issue of Suspect Mode can be addressed via different ways – specifically two, the first method requires the use of SQL statement parameters and the second is the direct recommendation to use SQL Database backups.
We’ll discuss both the methods one by one, starting with SQL statement parameters:
We’ll start by resetting the database status using which will turn off the suspect flag on the database.
yourDBname is the example database name, change it with a real database name.
This SQL statement parameter will change the database state and set it to Emergency to provide flexibility to perform tasks on a corrupt/suspect SQL database.
This statement will initiate a consistency check on the select database to find out changes or loss of data such as rows or columns.
Again, change yourDBname with your database name.
Executing DBCC checkdb can produce distinct results, which can decide whether to proceed with SQL statement parameters any further or not.
Below are those outcomes – proceed accordingly to the result you receive on-screen:
This SQL statement will initiate rollback all running transactions and set the SQL Server database in single user mode for maintenance purpose.
Upon completion of SQL server database repair – initiated in step-5, this statement will set the database back to multi-user mode.
Executing the above SQL statement parameter can fix the Suspect issue, execute as per the instructions mentioned above under notes.
If no inconsistency is found in step-3, there is no need for step 4-6 but go through the points given in step-3 and proceed as per the result you receive.
Now, before discussing the second method – primary & the recommended one, let’s shed some light on step-5:
It is strictly recommended not to run this statement if no inconsistency is found in step-3,
If Executed, What the Consequences Will Be?
We strictly recommend not to run this SQL statement if no inconsistency is found in the SQL database, otherwise risk of data loss will be there.
When the issue of database file corruption or damage or suspect mode occurs, in some cases due to the error ferocity, it becomes almost impossible to fix the issue and recover data.
The chances of the corrupt or damaged database file(s) recovery also turn negative in the absence of a full SQL Server Database backup.
