You occasionally need to perform maintenance tasks on dbccdb.
Reevaluate and update the configuration using:
sp_dbcc_evaluatedb – recommends values for configuration parameters using the results of previous dbcc checkstorage operations.
sp_dbcc_updateconfig – updates the configuration parameters for the specified database.
Clean up obsolete data in dbccdb:
sp_dbcc_deletedb – deletes all the information on the specified database from dbccdb.
sp_dbcc_deletehistory – deletes the results of the dbcc checkstorage operations on the specified database from dbccdb.
Remove unnecessary workspaces.
Perform consistency checks on dbccdb itself.
