Hi,

Could someone give pointers to get more information on the following topic?

>>>So, any better ideas how to achieve the hot-standby functionality? The
>>>basic requirement is that host A be able to vanish (as in the hardware
>>>just suddenly goes *POOF!* and is no longer there) and that requests (on
>>>persistent objects) be redirected to host B transparently to any client
>>>(in particular, clients should not have to get new object references).
>>>    
>>>
>>
>>You can publish the addresses of all the replicas in all the IORs,
>>
> How we do this on server side? How can I publish an IOR having address 
> of both Server A and Server b? In my case Server B is a hot-standy for 
> Server-A. So when server A goes down, client should start using
