DSXchange

Hi,

Whenever any changes happened to below MV Refresh job schedules, couple of jobs are getting missed out from the schedule. However, I did not see this issue when rest of the job schedules are changed. We are using Datastage 7.5.1 for scheduling these jobs.

MV Refresh Jobs:
LEDGER_BAL_MV
CMP_CC_HH_MV

Missing Jobs:
ORA_SJ_PGE_HIST
SJ_HS_JRNL_TRANS

We have been getting this issue only when the MV Refresh job schedules are getting changed. Moreover there is no dependency or relation between these jobs.

Could you please help me what would be the issue?

Thanks,
Karunakar

I doubt it has anything to do with your "MV" jobs specifically. Schedules are only shown to the scheduling user, are you sure you are checking with the proper userid?

Hi Chulett,

I logged in with the same User that was used to schedule the jobs. More over I can see that the jobs are intact before I change the MV Refresh job schedules.

Not sure what could be the reason. Did anyone come across this issue before?

Thanks,
Karunakar

Hello Karunakar,

DS does not have an inbuilt scheduler hence on UNIX it asks for help from AT (Utility for UNIX scheduling) or Cron (Master scheduler).

Once you schedule a job in DS, please logon with the same user on the command prompt and see youself. Use at -l for this purpose.

If someone issues at -r, all your scheduled jobs shall vanish. Get in touch with your System Admin if required.

P.S.
@Experts,
Many organizations spend thousands on buying a scheduling tool (Ctrl-M is my favorite). For an ETL tool, it is necessary to have this functionality on top of workflow (Called Sequence job in DataStage).

Many regards,

That information is out of date. With version 8 Information Server does have its own, in-built scheduling service and DataStage leverages that.

Right, thanks for sharing the information.

But, Karunakar's thread is about DataStage 7.5.1 and his query about his schedules suddenly vanishing.

Even with DataStage 8, the scheduling and reporting capabilities are cause of WebSphere. Situation very much similar to that of DataStage 7.1 or 7.5.x where UNIX provided the help or managed via Ctrl-M or similar tool.

In my opinion, DataStage is still handicapped when it comes to scheduling. Is it so difficult to write a small server program in C or assembly to behave like a personal scheduler ?

I wonder sometimes for what programs does our washing machines, television sets or refrigerators use for they too must be needing program schedules. Also, If they are in place why cant the same code be borrowed then.

Thanks.

Many regards,
