How to upload huge files to Oracle support

Oracle's ftp site can be used to do the job by following the below steps:

Move the file to your local machine and tar/zip them appropriately.

Open a command window.

Start ftp:
C:\T> ftp
ftp>

Connect to the oracle ftp server and connect as user anonymous:
ftp> open ftp.oracle.com
User (bigip-ftp.oracle.com:(none)): anonymous

Use as a password a valid email address used in metalink:

331 Please specify the password.
Password:
230 Login successful.

Move into the directory "support/incoming":

ftp> pwd
257 "/"
ftp> cd support/incoming
250 Directory successfully changed.

Create a new directory with the name of your service request number:
ftp> mkdir
257 "/support/incoming/" created
ftp> cd
250 Directory successfully changed.

Set the transfer mode to binary:
ftp> bin
200 Switching to Binary mode.

Put the files on the ftp server:
ftp> put

Use the command pwd to check the current directory:
ftp> pwd
257 "/support/incoming/"

REMARK: For security reasons the command ls cannot be executed

Exit from ftp site:
ftp> quit

Inform Support that the file has been uploaded in the following location:
