Avoid Parallel execution of dependent Boxes and usage of look back

[VEERA V]

Hi,

 

I have faced below scenario and wanted to clarify few things of Autosys behaviour and how we can use look back option.

 

Consider No date_Condition for both BOX.

 

BOX_B:

Condition: s(BOX_A)

 

BOX A completed at 10 AM Monday

BOX B completed at 11 AM Monday

 

BOX A triggered at 10:05  & B triggered 10:04 ( didn't wait for new run of BOX A) Next day.

Whether BOX B will consider Monday 10 AM completion of BOX A status and trigger BOX B on Tuesday? 

To handle:

Will below look back will work to avoid above unexpected scenario ? BOX B will trigger only after sucessfull next new run? please advise. how putting 0 will wait for 0 mins ? or how its work

 

Jil of BOX B would be as below 

BOX_B:

Condition: s(BOX_A,0)

 

Thanks in advance.

Hi Veera,

It sounds like there has probably been a failure in BOX_A at some point and then BOX_B has held onto the status of that. One thing you could do at the end of your batch is to inactivate both boxes in preparation for the next run.

You also correctly say that the usage of a lookback condition will assist in this scenario too. From the documentation on lookbacks, when you specify 0, AutoSys Workload Automation examines the last end time of the job first. It then examines the last end time of the condition job. If the condition job has run since the last run of the job for which the condition is coded for, the job is allowed to start. If the condition job has not run since the last run of the job for which the condition is coded for, the job is not allowed to start.

More information on lookback conditions can be found here:

Hope this helps!
