INFORMATICA 的元数据管理之二:运行状态信息查询

　　本项目里的两个哥们做的关于运行状态元数据的两个JOB挺酷的，最近一段时间运行状况良好，自己参考学习的同时以做日志记载，呵呵，为了节省笔墨，相关元数据表结构以及MAPPING设计之类不做介绍（如有疑问欢迎留言探讨），仅对思路做以梳理如下：

　　1. 通过WKF ID和TASK ID关联对应WKF,TAST,从而形成关于SESSION运行状态报表如下：

SELECT OPB_SUBJECT.SUBJ_NAME,

OPB_WFLOW_RUN.WORKFLOW_NAME,

OPB_TASK_INST_RUN.INSTANCE_NAME,

to_char(OPB_TASK_INST_RUN.START_TIME,'yyyy-mm-dd HH24:mi:ss') START_TIME,

to_char(OPB_TASK_INST_RUN.END_TIME,'yyyy-mm-dd HH24:mi:ss') END_TIME,

OPB_TASK_INST_RUN.RUN_ERR_MSG,

OPB_TASK_INST_RUN.TASK_NAME,

OPB_SWIDGINST_LOG.INSTANCE_NAME  INSTANCE_NAME_LOG,

OPB_SWIDGINST_LOG.WIDGET_TYPE,

APPLIED_ROWS                      SUCCESSFUL_ROWS,

AFFECTED_ROWS                     SUCCESSFUL_AFFECTED_ROWS,

REJECTED_ROWS                     FAILED_ROWS,

REPLACE(LAST_ERR_MSG,Chr('44'),Chr('35'))                      LAST_ERROR

FROM INFREP_V8.OPB_TASK_INST_RUN OPB_TASK_INST_RUN, INFREP_V8.OPB_WFLOW_RUN OPB_WFLOW_RUN, INFREP_V8.OPB_SUBJECT OPB_SUBJECT, INFREP_V8.OPB_SWIDGINST_LOG OPB_SWIDGINST_LOG

WHERE OPB_SUBJECT.SUBJ_ID = OPB_TASK_INST_RUN.SUBJECT_ID

AND OPB_WFLOW_RUN.WORKFLOW_ID = OPB_TASK_INST_RUN.WORKFLOW_ID

AND OPB_WFLOW_RUN.WORKFLOW_RUN_ID = OPB_TASK_INST_RUN.WORKFLOW_RUN_ID

AND OPB_SWIDGINST_LOG.WORKFLOW_RUN_ID =

OPB_TASK_INST_RUN.WORKFLOW_RUN_ID

AND OPB_SWIDGINST_LOG.TASK_INSTANCE_ID = OPB_TASK_INST_RUN.INSTANCE_ID

AND OPB_SWIDGINST_LOG.WIDGET_TYPE IN (3, 2)

and trunc(OPB_TASK_INST_RUN.START_TIME) = trunc(SYSDATE-1,'DD')

　　该QUERY显示的是前一天的SESSION运行状况报表，通过该报表可以系统的监控JOB的运行状况。

　　2. 下面的QUERY是用来记录WKF的运行状况监控报表/

SELECT   rep_workflows.server_name, rep_workflows.subject_area,

rep_workflows.workflow_name, rep_workflows.scheduler_name,

CASE

WHEN opb_schedule_logic.user_logic_type = 1

AND opb_schedule_logic.frequency_intervl = 1

THEN 'Daily Job'

WHEN (    opb_schedule_logic.user_logic_type = 1

AND opb_schedule_logic.frequency_intervl > 1

AND opb_schedule_logic.frequency_intervl < 8

)

THEN 'Weekly Job'

ELSE 'Monthly Job'

END job_type,

REPLACE (SUBSTR (rep_workflows.start_time,

-5,

5

),

'/',

':'

) schedule_time,

CASE

WHEN opb_wflow_run.run_err_code = 0 and opb_wflow_run.end_time is not null

THEN 'Completed'

WHEN opb_wflow_run.run_err_code = 0 and opb_wflow_run.end_time is  null

THEN 'Running'

WHEN opb_wflow_run.run_err_code >= 1

THEN 'Failed'

ELSE 'Not Start'

END status,

opb_wflow_run.start_time, opb_wflow_run.end_time,

--rep_workflows.start_time,

opb_wflow_run.run_err_code

FROM rep_workflows LEFT JOIN opb_wflow_run

ON opb_wflow_run.workflow_id = rep_workflows.workflow_id

AND TRUNC (opb_wflow_run.start_time) = TRUNC (SYSDATE, 'DD')

JOIN opb_schedule_logic

ON opb_schedule_logic.scheduler_id = rep_workflows.scheduler_id

AND opb_schedule_logic.version_number IN (

SELECT MAX (l.version_number)

FROM opb_schedule_logic l

WHERE opb_schedule_logic.scheduler_id =l.scheduler_id)

WHERE rep_workflows.run_options > 1

ORDER BY 1, 2, 3

以上仅是基于SESSION和WKF级别的监控元数据利用QUERY，如果需要设为自动每天/每周生成报表需要添加源元数据表和SQLQUALIFER组件后（一般还会过滤掉成功的状态，用FILER组件）进入目标表

然后添加个MAILTAST把运行异常状态报告表每天以邮件方式发送。
