Registering a target DB using RMAN

Oracle says you can register a target db (say T-DB) for the recovery catalog ( say R-DB which is on a seperate server) using RMAN.

(say JOHN is a user account having necessary privs for RMAN operations)

When we execute the command "RMAN target T-DB catalog JOHN/JOHN@R-DB"

Since R-DB and T-DB are on different servers, how will Oracle understand where the server and DB is located? Also, do we execute this command from the target server (T-DB) or from RMAN Recovery Catalog Server (R-DB)??

Kindly advise.

well it suppose to be

RMAN target username/password@T-DB catalog JOHN/JOHN@R-DB

even I can know where the server is located if I see that syntax and tnsnames.ora

you execute from anywhere, you have already told the target is T-DB and recovery catalog is in R-DB, enough info

Hi,
If u setup ur database network properly - tnsnames.ora at ur catalog database server then u r able to connect to database server.

Thank you. That should have been simple common sense for me. Anyway, so I can then register a target db either from the target db server or from recovery catalog server, as long as each is specified and identifed in the tnsnames.ora - RIGHT?

Many thanks.

yes
