Hi,
Thanks in advance for any replies.

Customer has this environment:

- a primary in city a, that has a logical standby connected locally.
- a physical standby of the primary in city b
- a logical standby of the physical standby in city b

All are on 10.2.0.4.  City B is the DR site.

Can the logical standby in city a use the logical standby in city b, as a logical standby?  i don't think its a good idea, but didn't know if in fact it was doable.

Thanks,
Steve

Howdy, Stranger!
