WHERE

AND RUN_STATUS = 'Failed' --session运行状态的筛选，若只想看失败的session信息，则令RUN_STATUS = 'Failed'；否则去掉该条件,此时可以看到所有session运行状态

ORDER BY RUN_DATE DESC, WORKFLOW, WORKLET_LVL3, WORKLET_LVL2, WORKLET_LVL1, SESSION_NAME --排序以更好的形式展示出来

查询得到的结果示例如下：

拿第一条举例，由RUN_STATUS这个字段内容（Failed）可以看出，ETL0_ODS这个folder下的WKF_ETL0这个workflow下的WKL_FMIS_GJXNY worklet下的WKL_T07 worklet 下的WKL_FMIS_APPLSYS worklet下的s_m_ods_fmis_applsys_fnd_flex_value_sets这个session调度出错了，出错原因是无法连接上数据库。

如果想让该SQL每天自动运行，然后将查数结果发送到邮箱的话，我的做法需要下面几个步骤：

（1）将该sql保存到Informatica服务器上的一个文件中（base_sql.txt），有可能需要去掉上面SQL里的中文注释。

（2）Informatica服务器上写一个shell脚本（workflow_dispatch.sh），脚本中调用sqluldr2命令来远程到Informatica资料库上执行base_sql.txt文件中的SQL语句，结果保存到一个文件中。命令如下：

 sqluldr2 user=${conn_str} sql=${py_file_dir}${sql_file} fast=yes field="," head=yes file=${result_dir}${result_file} escape='\' escf=0x0a esct=n

其中escape='\' escf=0x0a esct=n等参数设定是为了去掉sql执行结果中有的数据里面存在换行。

（3）执行完第二步之后，查数结果已经保存到某个文件中（ sqluldr2命令中file参数指定的文件）了，接下来只需在shell中调用相应的邮件服务命令将结果文件发送到邮件即可。至于Informatica服务器上的邮件服务，使用msmtp+mutt或者写python脚本或者其他的都行，我采用的python脚本的方式（sendmail.py）。若是想使用msmtp+mutt的方式，可参考以下链接进行配置：http://www.cnblogs.com/suhaha/p/8655033.html。

（4）虽然存放查数结果的文件占用空间不多，也应该在shell中定时删除太久之前的文件，比如每次都固定删除一个月之前的文件。

完整的workflow_dispatch.sh脚本示例如下：

#!/bin/bash

check_date=$(date +%Y%m%d_%H%M)

base_dir="/data/ODS_TO_EDW_DATACHECK/"
result_dir=${base_dir}"result_file/"

result_file="dispatch_result_"${check_date}".csv"
sql_file="base_sql.txt"
tar_file="dispatch_result_"${check_date}".tar.gz"
mail_file="sendmail.py"

echo "execute sqluldr2..."
echo -e "\n"

sqluldr2 user=${conn_str} sql=${py_file_dir}${sql_file} fast=yes field="," head=yes file=${result_dir}${result_file} escape='\' escf=0x0a esct=n

if [ $? -eq  ]; then
    echo -e "\n"
    echo "sqluldr2 run successful!"
    echo -e "\n"

    echo "check the count of error session..."
    cd ${result_dir}
    cnt=`cat ${result_file} | wc -l`
    cnt=`expr ${cnt} - `
    echo "[cnt of error sessions ]: "${cnt}
    echo -e "\n"

    #echo "compress the result file into : "${tar_file}
    #tar -czvf ${tar_file} ${result_file} && rm -rf ${result_file}

    echo -e "\n"
    echo "Send mail..."
    if [ ${cnt} -gt  ]; then
        python ${py_file_dir}${mail_file} "Result of Informatica Dispatch (PRD)" \
            "Infamatica Dispatch finish. "${cnt}" error sessions. Check the attachment for more details." ${result_dir}${result_file} $@
    else
        python ${py_file_dir}${mail_file} "Result of Informatica Dispatch (PRD)" "Infamatica Dispatch finish. No error." ${result_dir}${result_file} $@
    fi

else
    echo "sqluldr2 run failed!"
    exit
fi

完整的sendmail.py脚本示例如下：

        该脚本调用格式: python /data/ODS_TO_EDW_DATACHECK/py_file/sendmail.py  +theme +body +attachment +recipient1 +recipient2  + ... +recipients
        调用示例:python sendmail.py  "Result of DataCheck" "23333..This is body..."  /data/ODS_TO_EDW_DATACHECK/py_file/sendmail.py 983523649@qq.com

（5）在Informatica中新建一个Task，Task中调用shell脚本。如下图。然后在INFA每日调度的最后一个session或者最后一个workflow末尾加上该Task即可。

最后，当然INFA自身也能配置邮件服务，并且配置之后它的报错也能详细到session级别，如下图。说实话我没用过。

不过在项目的实施过程中，开发的session数量一般都是上几百个的，每个session都配置的话会比较麻烦；再者，假设真的每个session都配置了，然后每个session跑成功或者失败了都给你发一封邮件，一般INFA的调度还都在半夜，会疯掉的~

我之所采用上面描述的方法是因为：项目开发之初压根没考虑到调度的监控问题，都项目后期了前台数据对不上之后往前溯源了才发现是某个session挂掉好久了，因此才想起配置这么个东西。

另外，我觉得这种方式比INFA自身的邮件设置方式要相对好一点吧~INFA调度完成之后统一查询，速度快，效率也高，最重要的是每天只给你发一封邮件。。。
