Need to Enable DB Health check option

Hi,

I am using TOAD 10.1.1.8 DBA Suite.

As my TOAD DBA Suite, DB Health check option should be there under

Database -> Diagnose -> DB Health Check.

But its not showing this option.

Kindly guide me as How to enable DB Health check.

Expecting your valuable reply ASAP.

Thanks in advance,

Orahar.
