Home -> Community -> Mailing Lists -> Oracle-L -> RE: Email from PL/SQL with Java - UTL_SMTP - UTL_TCP
I use this facility and have no problems sending more than 4000 characters.
I created a package called pl_sql_mail to better communicate with the
Oracle delivered packages. This package will not fulfill everyone's needs;
I use it to email myself reports.
procedure contact_smtpsrv(sender in varchar2, recipient in varchar2);
procedure send_header (name in varchar2, header in varchar2);
procedure send_body(mail_text in varchar2);
procedure signoff_smtpsrv;
end plsql_mail;
package body plsql_mail as
c utl_smtp.connection;
procedure contact_smtpsrv(sender in varchar2, recipient in varchar2)
is
Begin
c := utl_smtp.open_connection('<your smtp server>');
utl_smtp.helo(c, '<your domain>');
utl_smtp.mail(c, sender);
utl_smtp.rcpt(c,recipient);
utl_smtp.open_data(c);
EXCEPTION
WHEN utl_smtp.transient_error OR utl_smtp.permanent_error THEN
utl_smtp.quit(c);
raise_application_error(-20000,
'Failed to send mail due to the following error: ' ||
sqlerrm);
end contact_smtpsrv;
PROCEDURE send_header(name IN VARCHAR2, header IN VARCHAR2) is
BEGIN
utl_smtp.write_data(c, name || ': ' || header || utl_tcp.CRLF);
end send_header;
Procedure send_body(mail_text in varchar2) is
Begin
utl_smtp.write_data(c, utl_tcp.CRLF || mail_text);
end send_body;
Procedure signoff_smtpsrv is
Begin
utl_smtp.close_data(c);
utl_smtp.quit(c);
end signoff_smtpsrv;

Subject: RE: Email from PL/SQL with Java - UTL_SMTP - UTL_TCP
OK, now I'm becoming an addict 'cause I just sent an email to myself from PL/SQL. Pretty cool. Now many of my UNIX scripts are going to take a back seat to PL/SQL. But I do generate some reports which probably exceed 4000 characters. Oh well...
Thanks,
Steve Orr

Since I'm addicted to email notices, I configured my own instance with the UTL_SMTP package. I wrote some "wrapper" PL/SQL so that I can invoke a procedure & pass in three arguments; sender_name, recipient_list, & message (a text string). On my 8i instances I created DB triggers to send email messages upon startup & shutdown. On the V7 instances within the Unix scripts I invoke SQL*PLUS which runs a PL/SQL procedure that passes the same three arguments to MY V8.1.6 instance. Therefore all my DB's send me a message when they transistion state. All was done in PL/SQL; & no JAVA. In other words, I have a single DB that handles the SMTP interface for all the other DBs I support.
My message length is limited to the maximum length of a single VARCHAR2 variable in PL/SQL, but it satisfies my needs so far.
