[oracle@station78 ~]$ cd $TNS_ADMIN
[oracle@station78 admin]$ cat tnsnames.ora | head -n 12
CATALOG =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = station78.example.com)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = catalog)
    )
  )
[oracle@station78 admin]$ lsnrctl start
[oracle@station78 admin]$ tnsping catalog
...................
Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = station78.example.com)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = catalog)))
OK (0 msec)

@@@Note:
@@@as the client of catalog, my shell assigned the tns is "rmandb"
@@@you must make sure has rmandb point to the catalog db. as the below:
RMANDB =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = station78.example.com)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = catalog)
    )
  )

3@@@@ example
$rman target / catalog ucata/oracle@rmandb
rman> cretae catalog tablespace tbscatalog;  @@@create catalog ; drop catalog
rman> register database     @@@unregister database;
rman> resync catalog     

$rman target / catalog ucata/oracle@rmandb
rman> set dbid 19293242   @@@if you have many db register the database
