Agree! A more meaningful way to present this picture is to have multiple, at least two pictures. They have the same content, except for an extended RAC, most of the items slightly toward the right will move further right, and possibly further up, compared to them for a local RAC + data guard. What do you think?
> 如果一个 FG2 完全损坏, 是否可以再加入一组 FG3 ,因是normal 冗余设置, 那么FG1 上的数据是否会balancing一份到FG3 ?
Why not?
> DB_LOST_WRITE_PROTECT , DB_ULTRA_SAFE ?
Has anyone had real experience with these two parameters? We never bothered to check. Only did some basic reading. |
