导出远程数据库：Oracle

Question

I have an oracle database on a server that contains more than one database, i'm connected to those databases using sqlDevelopper normaly. I want to export the database DB1. The string connection used in SqlDevelopper is :

user@//server:1530/DB1
user@//server:1533/DB2
user@//server:1534/DB3

The command i use to export the DB1 is :

exp user@//server:1530/DB1 file="C:\\DB1.dmp" log="C:\\DB1.log" rows=y owner=user

But it doesn't work, i have this message :

 EXP-00056: Erreur ORACLE 6401 rencontré ORA-06401: NETCMN : désignation de lecteur non valide EXP-00000: Procédure d'export terminée avec erreur 

How can I adjust the exp command to have the desired result?

Following on from comments suggesting you're using a pre-10g version that doesn't support the easy connect syntax, and therefore also can't use data pump ...

If you've created a tnsnames.ora entry like:

BD1 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP) (HOST = server) (PORT = 1530))
    )
    (CONNECT_DATA = (SERVICE_NAME = DB1))
  )

... then you should be able to export using:

exp user@BD1 file="C:\DB1.dmp" log="C:\DB1.log" rows=y owner=user

(where BD1 is the alias name; not sure if you intended to spell it like that, but you could use DB1 if you preferred).
