该程序脚本最主要的功能实现为通过oracle自带的过程包发送邮件来监控ETL的执行情况：

export ORACLE_SID ORACLE_BASE ORACLE_HOME

while read gameuser
do
echo ${gameuser}
echo ${SQLPLUS}
cd ${PWD_DIR}
${SQLPLUS} ${gameuser} << !
@etl_monitor.sql;

exit;

作用：用oracle发送邮件
主要功能：1、支持多收件人。
2、支持中文
3、支持抄送人
4、支持大于32K的附件
5、支持多行正文
6、支持多附件
7、支持文本附件和二进制附件
8、支持HTML格式
8、支持
作者：suk
参数说明：
p_txt :邮件正文
p_sub: 邮件标题
p_SendorAddress : 发送人邮件地址
p_ReceiverAddress : 接收地址，可以同时发送到多个地址上，地址之间用","或者";"隔开
p_EmailServer : 邮件服务器地址，可以是域名或者IP
p_Port ：邮件服务器端口
p_need_smtp：是否需要smtp认证，0表示不需要，1表示需要
p_user：smtp验证需要的用户名
p_pass：smtp验证需要的密码
p_filename：附件名称，必须包含完整的路径，如"d:\temp\a.txt"。
可以有多个附件，附件名称只见用逗号或者分号分隔
p_encode：附件编码转换格式，其中 p_encode='bit 7' 表示文本类型附件
p_encode='base64' 表示二进制类型附件
注意：
1、对于文本类型的附件，不能用base64的方式发送，否则出错
2、对于多个附件只能用同一种格式发送
