Resetting the Suspect Status

Microsoft® SQL Server™ 2000 returns error 1105 and sets the status column of sysdatabases to suspect if SQL Server is unable to complete recovery on a database because the disk drive no longer has any free space. Follow these steps to resolve the problem:

1. Execute sp_resetstatus.
   
   
2. Use ALTER DATABASE to add a data file or log file to the database.
   
   
3. Stop and restart SQL Server.

   With the extra space provided by the new data file or log file, SQL Server should be able to complete recovery of the database.

4. Free disk space and rerun recovery.

sp_resetstatus turns off the suspect flag on a database, but leaves all other database options intact.

Caution  Use sp_resetstatus only when directed by your primary support provider or as recommended in Troubleshooting. Otherwise, you might damage your database.

Because this procedure modifies the system tables, the system administrator must enable updates to the system tables before creating this procedure. To enable updates, use this procedure:

USE master
GO
sp_configure 'allow updates', 1
GO
RECONFIGURE WITH OVERRIDE
GO

After the procedure is created, immediately disable updates to the system tables:

sp_configure 'allow updates', 0
GO
RECONFIGURE WITH OVERRIDE
GO

sp_resetstatus can be executed only by the system administrator. Always shut down SQL Server immediately after executing this procedure.

The syntax is:

sp_resetstatus database_name

This example turns off the suspect flag on the PRODUCTION database.

sp_resetstatus PRODUCTION

Here is the result set:

Database 'PRODUCTION' status reset!
WARNING: You must reboot SQL Server prior to accessing this database!

sp_resetstatus Stored Procedure Code

Here is the code of the sp_resetstatus stored procedure:

IF EXISTS ( SELECT * from sysobjects where name = 'sp_resetstatus' )
   DROP PROCEDURE sp_resetstatus
GO

CREATE PROC sp_resetstatus @dbname varchar(30) AS
DECLARE @msg varchar(80)
IF @@trancount > 0
      BEGIN
         PRINT 'Can''t run sp_resetstatus from within a transaction.'
         RETURN (1)
      END
IF suser_id() != 1
      BEGIN
         SELECT @msg =  'You must be the System Administrator (SA)'
         SELECT @msg = @msg + ' to execute this procedure.'
         RETURN (1)
      END
IF (SELECT COUNT(*) FROM master..sysdatabases
         WHERE name = @dbname) != 1
      BEGIN
         SELECT @msg = 'Database ' + @dbname + ' does not exist!'
         PRINT @msg
         RETURN (1)
      END
IF (SELECT COUNT(*) FROM master..sysdatabases
         WHERE name = @dbname AND status & 256 = 256) != 1
      BEGIN
         PRINT 'sp_resetstatus can only be run on suspect databases.'
         RETURN (1)
      END
BEGIN TRAN
      UPDATE master..sysdatabases SET status = status ^ 256
         WHERE name = @dbname
      IF @@error != 0 OR @@rowcount != 1
         ROLLBACK TRAN
      ELSE 
         BEGIN
            COMMIT TRAN
            SELECT @msg = 'Database ' + @dbname + ' status reset!'
            PRINT @msg
            PRINT ''
            PRINT 'WARNING: You must reboot SQL Server prior to  '
            PRINT '         accessing this database!'
