Oracle管理监控之使用utl_mail自动邮件报警配置

--代发邮件存储过程源码如下：

CREATE OR REPLACE PROCEDURE send_mail(p_recipient VARCHAR2, -- 邮件接收人
                                      p_subject   VARCHAR2, -- 邮件标题
                                      p_message   VARCHAR2 -- 邮件正文
                                      ) IS

--下面四个变量请根据实际邮件服务器进行赋值
v_mailhost VARCHAR2(30) := 'smtp.szlongtu.com'; --SMTP服务器地址
v_user     VARCHAR2(30) := 'wcwen@qq.com'; --登录SMTP服务器的用户名
v_pass     VARCHAR2(20) := 'XXXXXX'; --登录SMTP服务器的密码
v_sender   VARCHAR2(50) := 'wcwen@qq.com'; --发送者邮箱，一般与 ps_user 对应

v_conn UTL_SMTP. connection; --到邮件服务器的连接
v_msg varchar2(4000); --邮件内容

BEGIN

v_conn := UTL_SMTP.open_connection(v_mailhost, 25);

--否则会报：ORA-29279: SMTP 永久性错误: 503 5.5.2 Send hello first.

UTL_SMTP.command(v_conn, 'AUTH LOGIN'); -- smtp服务器登录校验
UTL_SMTP.command(v_conn,

-- dbms_output.put_line('...........................');

UTL_SMTP.mail(v_conn, '<' || v_sender || '>'); --设置发件人

UTL_SMTP.rcpt(v_conn, '<' || p_recipient || '>'); --设置收件人

-- 创建要发送的邮件内容注意报头信息和邮件正文之间要空一行
v_msg := 'Date:' || TO_CHAR(SYSDATE, 'dd mon yy hh24:mi:ss') ||

           UTL_TCP.CRLF -- 这前面是报头信息
           || p_message; -- 这个是邮件正文
dbms_output.put_line(v_msg);
UTL_SMTP.open_data(v_conn); --打开流
UTL_SMTP.write_raw_data(v_conn, UTL_RAW.cast_to_raw(v_msg)); --这样写标题和内容都能用中文
UTL_SMTP.close_data(v_conn); --关闭流
UTL_SMTP.quit(v_conn); --关闭连接

EXCEPTION
