how to stabilize plan for materialize view.
We have recently upgraded from 11g to 12c. And few of the MV's are showing poor performance, I checked their execution plan in source instance and it was different.
I moved the sql plan from source to target , but MV is still not picking that plan. I tried this 3/4 times and it's not working. Whereas for normal queries moved plans are working.
Is there any different way to stabilize plan for MV's ?
Thanks
