A production environment, the basic situation is that an application Server, an IIS Server, an Oracle Dataguard Primary Server, an Oracle Dataguard Standby servers, a total of 4 Server, system are Server 2012,

Now consider is the extreme situation, for example, room explosion, all over, like this kind of situation, of course spare that a server is not in the same building, will survive,

How it survived the standby machine, on the top of the moment? How to configure the standby machine, using any ideas?

, of course, if such a big wrong, unknown the truth to eat the melon masses, 45 degree Angle look up at the light in the room building, can eat a long melon, stop for a few hours, estimate can also accept, for a period of time before somebody else WOW room no explosion, also some people are willing to wait for a few hours, how much something,

CodePudding user response:

This will consider automatic switch, but it such a big deal out of the floor, the best or manual switch once more appropriate,
