In this video I have explained how we can avoid a common error which one can easily get while creating blackout in OEM12c. I got complaint from my team members that when ever they create blackout for some maintenance activity it is getting failed every time.
I tried to find out the reason for the same and asked my team mate show me how he is creating blackout. I created using the same method which he did and the strange thing was that I did not get that error.
I took some time to analyze the root cause and found that there was something un common in the drop down menu to select targets. The whole thing is explained in this video.
