Solve SQL Server Error 9100 with DBCC CHECKDB Command

Running the DBCC CHECKDB is recommended action for solving the error. The physical and logical inconsistencies among the database objects are checked by the database console commands.

  • The following parameters are testified in the database tables:
  • The rational amount of data on each table
  • Proper sorting of the indexes
  • Appropriate volume of page offset
  • Consistency among pointers
  • Appropriate linking of data pages and indexes

The DBCC CHECKDB command includes three subcommands that are-

  1. DBCC CHECKALLOC- The space allocation structure of database on disk is checked for consistency.
  2. DBCC CHECKCATALOG- The system table of the specified database is checked for consistency. It ensures that each data type is assigned to a matching entry in the syscolumns and systypes. Also, it ensures that each view and table has a minimum of one column in syscolumns of sysobjects.
  3. DBCC CHECKTABLE- This command checks the integrity of the text, images, data, index and next pages for the database table. The indexed views and tables are checked for consistency.

Note: The above commands don’t need to be run separately as they are automatically executed when DBCC CHECKDB is implemented.

Permissions required to execute the DBCC CHECKDB Command
The user must be a member of

  • sysadmin fixed server role OR
  • db_owner fixed database role

This is the authority required by the user to execute the DBCC CHECKDB command on the specified SQL database table.

Approach #2: Restore from Backup

There are chances that the SQL server error 9100 will not get resolved by DBCC execution. Then the other approach is to perform the backup restoration.

When the database is restored from the most recent backup files, only the latest data will be lost and the rest will be restored. Evidently, full restore of the backup data helps in restoring the database components back to their original spots.

Some Points to be Considered for Creating Backups

  • The regular backup of database items is always recommended and it has to be made a ritual or a habit.
  • The backup of the data can be best stored at some off-site location with minimum access.
  • The backup of data is application oriented and doesn’t require any extra resources.

Backup and restoration involves strategies related to-

  • Planning
  • Implementation
  • Testing

Also, the backup restore operations manual is to be maintained to avoid critical scenarios and also to prove helpful in such scenarios.

Limitations of the Manual Methods
