I doubt that this would help the original poster since one of the databases is Oracle 7 which does not support import or export of transportable tablespaces.

Using the DIRECT=Y option will certainly speed up the export, but will not help the import.

Another option to try would be to set up a database link to the remote database and then use an INSERT with SELECT statment. For instance, if there was a "remote_db" link to the remote database, then on the local system, one could issue:

   INSERT INTO remote_table_at_remote_db SELECT * FROM local_table; Or you could go the other way, make the source database the remote one. Additionally, you could use the COPY command.

HTH,
