DCM with instable clock

So, I should use LOCKED and DO(1) to reset my DCM outside of FPGA, or
I can reset DCM inside FPGA using another clock_input. Only these 2
solutions?

Maybe I will do it in my next design, I cannot use DCM these time.

Anyway, thanks, all of you.

Yes,

Next time, be sure you have a local oscillator--your life will be far
easier.
