通过oracle存储过程发送邮件完成ETL监控

    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：

ORACLE_SID=orcl
ORACLE_BASE=/opt/oracle
ORACLE_HOME=/opt/oracle/product/10.2.0
export ORACLE_SID ORACLE_BASE ORACLE_HOME

PWD_DIR=/home/oracle/shell
SQLPLUS=${ORACLE_HOME}/bin/sqlplus
CONFIG_INI=${PWD_DIR}/ini/config.ini

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


etl_monitor.sql脚本为：

DECLARE
   p_txt VARCHAR2 (4000);
   p_txt_all VARCHAR2 (4000);
BEGIN
   FOR r IN (SELECT job_name,

      -- Call the Etl Monitor function

      p_txt :=
         etl_monitor (r.job_name,
                      r.run_cnt,
                      r.table_name,
                      r.column_name);
