Re: ORA-24247: network access denied by access control list (ACL) damorgan Jan 5, 2010 11:34 PM (in response to 727082) When you tell us what you did but don't post the actual code how can we possibly know what you did incorrectly? There are working demos here: http://www.morganslibrary.org/reference/dbms_network_acl_admin.html perhaps they will help you. If not then you need to post your real code. We can not debug what we can not see. 1 person found this helpful Like Show 0 Likes(0) Actions 2.

Slight buggette. You need to do a get_reply after doing a transfer to pickup the 226 Transfer complete message otherwise you can;t do subsequent get or puts as your reply processing trys to interpret the 226 as a port message when entering passive modeMike said...Great example. My only issue was that because this was my first time using UTL_FILE, I didn't know that UTL_FILE only has access to directories listed in INIT.ORA (utl_file_dir = ). Otherwise, things worked great! Tim... said...Hi. The UTL_FILE_DIR parameter does not need to be specified if a directory object is used. It is only relevant if you use an explicit path, which is not the recommended way to use UTL_FILE in 9i onwards. Cheers Tim...Tim... said...Trevor Woolnough: I've amended the ftp.pkb code and credited you in the amendment history for spotting the issue. Cheers Tim...Dario Romare said...After a long and ineffective search through DBMS_PIPE, UTL_TCP, DBMS_JOB, UTL_INADDR etc., it was great to find this very useful, ready-made code. Thanks !Sujay said...Tim, Wonderful code. Just one issue with this. It cannot put a zero byte file. It throws an exception. I have modified the code slightly in get_local_ascii_data and get_local_binary_data to fix this and it works fine.Barry Chase said...I would like to share my work with anyone who wants it. I have done a lot of work with this code in combination with several other sources researched. We are currently using my code in our production environment. It is on its 3rd revision.
