Is any one aware of how do new and exiting DFF's frozen property behave post 12.2 upgrade. We see that most of the new DFF's are not frozen which still seems fine since we may need to define and then freeze them. However we noticed that some of existing DFF's from 11i too are not frozen . I did see some Oracle notes about this issue but is any one aware of what is the general expected behavior ?
I'm not aware of any specific bugs. Have you encountered some existing DFF's which were in use and frozen, however are now not frozen? If so, are the DFV's compiled?
