Hi,

I would like to know , just in case CHECKDB maintenance job is running for 5 hours and admin chosen to kill that operation.

Usually the job takes not more than 2 hrs.

What can happen if CHECKDB is killed in the middle of process?

What are steps to be taken care even before thinking of killing CHECKDB operation ?

Did anyone faced this situation any time? if so, please do share on how to handle such situation.

Thanks in advance.

The CheckDB operation stops.

Is there anything happens internally because even the KILL takes a long time.

Thank you Gail. Again, in the fist place , is it perfectly safe to KILL checkdb operation if required?

It's perfectly safe to kill anything (well, unless your developers have written procedures which don't use transactions, but that's not a SQL internals problem)
