Sending email from the Oracle Database is very simple and straight forward with the UTL_SMTP package supplied in Oracle8i V8.1.6 (release 2). To send email using the UTL_SMTP package, you need to install the required Java classes and configure your SMTP server. You do not need to learn any new language to enable this functionality. It will be written in PL/SQL.
The environment used to enable this functionality was Oracle 8.1.6 on Sun Sparc Solaris 2.6 for the backend and Oracle Application Server 4.0.8 residing on NT4.0.
Steps for enabling email functionality from the Oracle Database:
I.Install the required Java Classes:
The required Java classes are automatically installed during the typical installation of the Oracle Software, however, they are not installed during custom installation. To install the required Java classes, perform the following commands:
Connect as SYS User.
II.Configure the SMTP server:
Get the SMTP server configured, the Unix Admin can help you with the configurations.
III.Write the PL/SQL Code:
Your code will loom like this:
CREATE OR REPLACE PROCEDURE send_mail
( sender IN VARCHAR2,
recipient IN VARCHAR2,
subject IN VARCHAR2,
message IN VARCHAR2)
mailhost VARCHAR2(30) := 'smtp01.us.oracle.com';
'Mailhost' is the name of the remote host when connection is established. The port number on which SMTP server is listening is usually 25.
Open_connection(): Allows open connection to an SMTP server.
Helo(): Performs initial handshaking with SMTP server after connecting.
Mail(): Initiates a mail transaction with the server. The destination is a mailbox.
Rcpt(): Specifies the recipient of an email message.
