v8 ESE installed on the server. It has several remote databases, I was told that all target databases are located on z/OS. From 'list node directory', I can guess it from the node name (it starts with DSN), but not all. When I do 'list dcs applications', I don't see any connections. I don't know the user id/password to try to connect to them.
How can I verify that all target databases are on z/OS? I know the IP address, but I can't tell if this IP belongs to AIX, z/OS, etc... without asking other people.
