OK. I have Oracle database on one machine and files that contain data source for external tables on another.
If FTP or NFS mounting are not recommended, what other options do I have?
My understanding is that DBMS_FILE_TRANSFER is for transferring files between Oracle databases. Can it also be used for moving ASCII files from a non-Oracle machine? Received on Sat Aug 19 2006 - 10:02:32 CDT
