ora_10g_db = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP) (HOST = ora10ghost.acme.com) (PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = orcl) ) )You can call this tns alias anything you want. I called it "ora_10g_db," but you can use any meaningful name you want. You will also have to change the database HOST, the PORT of the Oracle Listener on that server and the database SID (SERVICE_NAME) to match the values specific to your Oracle 10g database. Once done, you can connect to that database with the export utility in your Oracle 9i server as follows:
exp userid=system@ora_10g_db file=.....The "@ora_10g_db" tells exp that this is a remote database and to look up the connection information in the tnsnames.ora configuration file.
