I am using TOAD 13.2.0.258, I do not see a tab which reports "Redo log Frequency Map". These are the tabs i see Database\Diagnose(Code Analysis and TKprof wizard).
Is this feature still available in toad?
That feature was not removed.
It sounds like you used to have a DBA module in your license and now you don't.
Check under Help->About
Or maybe you hid those windows.
Check under Options -> Windows. Is it listed there? If so, is the "Available" column checked?
Under \View\Toad Options\Windows, I see a list of all these features, all checked in as "available"
