Is there any command line interface to call the send mail function in windows ?

In order to send email within 10g you must install and set up the UTL_MAIL package.
UTL_MAIL isn't installed when the database is installed because the SMTP_OUT_SERVER parameter must be configured. Listing 1 shows how to install UTL_MAIL and the results from the script. You must connect to the database as user SYS and run the two scripts identified in the listing.
Listing 1. Installation of UTL_MAIL
SQL> connect sys/password as sysdba
Connected.
SQL> @$ORACLE_HOME/rdbms/admin/utlmail.sql
Package created.
Synonym created.
SQL> @$ORACLE_HOME /rdbms/admin/prvtmail.plb
Package body created.
No errors. Next, the SMTP_OUT_SERVER parameter must be configured. You must connect to SYS and then use the alter system command to configure SMTP_OUT_SERVER parameter as shown here:
SQL> alter system set smtp_out_server = '<ip-address:port' scope=Both;
System altered.That's it! The installation and setup for UTL_MAIL is complete. The UTL_MAIL package only has one procedure, called Send, for sending email (see Listing 2 for the syntax for the Send procedure). This package bundles the email message and sends it to the UTL_SMTP package, and then the email message is sent to the SMTP server.
Listing 2. Syntax for UTL_MAIL.SEND
UTL_MAIL.SEND( sender IN VARCHAR2,
                                 recipients IN VARCHAR2,
                                cc IN VARCHAR2 DEFAULT NULL,
                                bcc IN VARCHAR2 DEFAULT NULL,
                                subject IN VARCHAR2 DEFAULT NULL,
                                message IN VARCHAR2,
                                mime_type IN VARCHAR2 DEFAULT
                                'text/plain; charset=us-ascii',
                                priority IN PLS_INTEGER DEFAULT  NULL);
Examples: I've created a database trigger that will send an email using UTL_MAIL (see Listing 3).
Listing 3. Database shutdown using UTL_MAIL
CREATE OR REPLACE TRIGGER SCOTT.db_shutdown
before shutdown on database
begin
utl_mail.send(
   sender => '[email protected]',
   recipients => ' [email protected]',
   subject => 'Testing utl_mail',
   message => 'The receipt of this email means'||
    ' that shutting down the database'||
    ' works for UTL_MAIL '
end;
