The indexes are properly sorted. The volume of page offsets is appropriate. This command includes three sub commands and they are summed up herein: DBCC CHECKALLOC: Performs consistency check over the space allocation structure of database on disk. DBCC CHECKCATALOG: It performs consistency checks in the system table of specified database. It ensures that: In syscolumns and systypes, each data type is assigned with a matching entry. In sysobjects, each view and table has minimum of one column in syscolumns. DBCC CHECKTABLE: The command is used to check integrity among text, index, data, images and next pages for the DB table. It performs consistency check over indexed views and tables. Note: All the above mentioned commands are executed automatically when DBCC CHECKDB is implemented.

Your answer could be in a dump log-file. If you still have a default trace from the time of the incident, you could try to look in the trace-files (*.trc) in the LOG-folder. Hint - Secure the trc-files by copying them to another folder before reading. I hope you find your root-cause. /niels share|improve this answer answered Sep 8 '14 at 12:17 nielsgrove 212 Man it was helpful but didn't solve :( Tried to bump your rep up but didn't allow because I didn't have enough reps.

Diagnosticando oproblema 9 set Publicado por Marcos Freccia Olá pessoal, Estou a algum tempo sem escrever nada tecnico e essa semana me deparei com um problema um tanto quanto chato, porem acho que será de extrema importancia relatar ele aqui para todos. Com certeza devemos ter outras referencias na web, então aqui será apenas mais uma fonte. Problema Sexta-feira 18:00 recebo o seguinte e-mail do SQL Server: “Possible index corruption detected. Run DBCC CHECKDB.” Entretanto um erro um tanto quanto estranho, já que o error id era 9100 e não os famosos 823 e 824. O pior de tudo isso era o problema não retratar em qual base de dados o erro se encontrava. Fiz uma pequena pesquisa no connect e encontrei essa sugestão, e peço que todos votem na mesma. Improve Error Message Quality : 9100 Possible index corruption detected. Run DBCC CHECKDB Passos para descobrir o problema Qualquer DBA que se preze irá rodar o seguinte comando: DBCC CHECKDB(DatabaseName) WITH NO_INFOMSGS, ALL_ERRORMSGS. O problema foi que não foi encontrado nenhum erro em todas as bases de dados, e o erro não parava de aparecer. Certo momento lembramos que 80% das bases que estavam naquela instancia, tinham sido migradas de SQL Server 2000 para SQL Server 2008 R2 e com isso uma palavra veio na mente DATA_PURITY. Começamos a rodar o DBCC CHECKDB(DatabaseName) WITH DATA_PURITY, NO_INFOMSGS,ALL_ERRORMSGS e assim conseguimos descobrir o seguinte erro em uma das bases. Assim conseguimos descobrir aonde estava o possivel corrompimento. Para aqueles que querem entender mais sobre o DATA_PURITY e o porque desse problema, é só clicarem nos links que estão acima. Quais os registros afetados? Como vocês podem ver na imagem do erro acima, o SQL Server mostra exatamente as paginas de dados afetadas pelo problema. Como temos a pagina de dados o troubleshooting fica muito mais facil, pois temo
