Brent Ozar shows how to support running DBCC CHECKDB on a log shipping subscriber:
At first glance, if you set up log shipping the way most folks do, it looks like you can’t run CHECKDB on a subscriber:
On SQL Server Enterprise Edition, you can try working around it by creating a database snapshot – but that won’t work either:
Here’s the trick: your database needs to be in standby mode instead of norecovery. When you run restores with the standby option, you’re able to query the database in between restores.
This doesn’t obviate the need for running CHECKDB on a primary, but it can offload some of that work some of the time.
