Re: RMAN connection error

Li Li


there's no solution yet, our network guys are looking into it. I thought the problem is the firewall because I can connect to the target using RMAN from another machine outside of the lab (our lab network is seperated from the production).

What was the solution - did you/they disable the firewall completely, or just open certain ports or IP addresses?  I don't know that much about firewalls - maybe they can be configured to allow only certain programs through too, e.g. they could set it to only allow sqlplus on port 1521 (or whatever your listener is on) - and not allow rman or any other program?  Any other network savvy folks on the list know if that's possible?

I am wondering this too. They are both connecting to the listener on the same port. I was thinking maybe there's some other ports that RMAN uses too?
