Oracle Database Discussions

All,

I am trying to FTP file from AIX Version 6 server to a VMS server using Oracle 10g stored procedure.
The procedure is able FTP the small sized files fine.
When i try to FTP large files, it throws error:
"The system encountered an error while trying to read file in the directory"
The file has all the RW rights granted to it.
When i manully FTP the file connecting to the server, the file transfers fine.
But will not FTP through the Stored Procedure.

Can anyone tell me if there is any restrictions on FTP transfers? What can cause this problem?

Thanks for any help,
Viji
