Hi.

I can able to send mail from the unix using mailx command but when I use the following snippet in sql*plus tool, it is showing network error.

declare
c utl_tcp.connection;
a exception;
pragma exception_init(a,-29260);
begin
c := utl_tcp.open_connection('127.0.0.1', 25);
dbms_output.put_line('Opened Successfully');
utl_tcp.close_connection(c);
exception
when a then
dbms_output.put_line('Network Error');
when others then
dbms_output.put_line('Other Error'||chr(10)||sqlerrm);
end;

Please let me know whether some service has to run in UNIX to use utl_tcp package?

Thanks.

In 9i, use utl_smpt.
Search on AskTom there are several threads on this subject there.

dbms_output.put_line('Opened Successfully');
utl_tcp.close_connection(c);
end;

I don't see the difference with the previous one.
Do you read the link?
Do you use the preview button?

Do you have someone listening at port 25 in your local host?

I don't find any smtpd daemon in my servers... Should be some name for the SMTP daemon...

Thanks.

Try to open a telnet session to port 25 of the db-server
If you run into trouble with stuff like this, start by peeling of as many layers of complication as possible.
In this case, test it without the database layer in between.

No idea why did you move this thread to different group without answering my query.
As I said earlier, I can send mail using mailx command but not with utl_tcp package.

You suggested some possibilities but nothing works. Is there any expert there to answer my thread?

Thanks.

How can you know who moves the thread if he did not say he move it? What does make you say he didn't answer?

use "netstat -nv"

I moved your post from the pl/sql experts to here, because this does not involve expert pl/sql knowledge.

If a telnet to port 25 does not work, you have no smtp daemon on that box listening to port 25. This is not a database or pl/sql issue. I don't know what MTA mailx uses, but apparently not an SMTP-service.
First configure your box, and when you can send mail through a telnet session, only then move a step further and try to do it from the database.

Or it is configured to use a SMTP service on another box.

@shahnazurs
Your netstat output clearly shows that noone is listening on port 25.

I move the thread to Unix forum which is more its place.

Thanks all for your suggestions.

I will be checking with my system admin regarding which service is being used by MTA mailx command.

Michel,
You said again about the telnet 25, if I can able to send mail using mailx command then this ensure mail server is configured. Please correct me if I am wrong.

Thanks.

Yes but it does not mean that the service resides in THIS box.

Is it possible to check whether sendmail daemon uses which box/server's SMTP services?

Thanks.

Yes. Send an e-mail to the network/mail administrator asking him :

Which SMTP server should I use for my project?


Since he is probably the only one who can tell you definitely. He also might have different SMTP servers running in a backup/failover scenario and would want you to use a specific DNS name alias or something in your code.
