Does anyone Know where I can find instance, catalog information, like where it's stored things such when using catalog tcpip node command or by using client configuration stuff? Does have any system table or command that shows it?
to do a select on a instance catalog is a problem, because, imho, there are no tables for it. these information are stored in some files (some of them I know where are), but they are pretty unreadable.
But I assume, there IS a way, sice 'db2cc' does it, but truthfully, I have no idea at the moment. I will ask around, and when I find this out, I will let you know.
