This is not exactly a new type question. Various people will have different answers here.

On most of my dev/test databases ... no I don't use it multiple members in a redolog group usually.

Production databases I will go case by case. Highly critical systems sure why not.

Have I ever lost a redolog group or just one member of a group? Not so far ... Received on Fri Apr 29 2011 - 14:01:43 CDT
