Server Integrity Check CheckCommands question

Question

I am trying to figure out what is the best CheckCommands option for ServerIntegrity check.

1. Should I leave the job defaults as is?

   EXECUTE [dbo].[DatabaseIntegrityCheck] @Databases = 'USER_DATABASES', @LogToTable = 'Y'
   

2. Should i run the CHECKALLOC,CHECKTABLE,CHECKCATALOG option separately or is it included in the above? Same for the CHECKFILEGROUP option.

Answer 1

If you run the base CHECKDB command, you don't need to run the others. The other commands make up what is run by the full command.

See:

• CHECKDB From Every Angle: Complete description of all CHECKDB stages

• CHECKDB From Every Angle: Consistency Checking Options for a VLDB

Breaking the full check into its constituent parts is sometimes done on very large databases where a full check in total is too time consuming or gobbles up too many resources.

The only CHECKDB option that results in a different full check (PHYSICAL_ONLY) runs fewer overall checks. It skips logical checks against the data and only checks the physical file structure.
