Hi forumers, I've encountered these statements while reading DBA Fundamentals 2
"Multiple global names can be aliased to the same IP address in the host file and host naming can be used to connect to any of these databases even if they're on the same node"
Is this statement pointing to tnsnames.ora file?
"Can only be used to identify one SID per node; other SID can be identified by using the other naming methods"
on this statement, can this be an indirect answer to the question, what is the difference between host naming and local service naming?
