This question is specific to Zeke Scheduler for Z/OS.
Is it possible to find if a job is indirectly dependent on another job.
I can check the direct predecessor and successor of the job. But if I want to find if job A is dependent on job B, I have to check all the successor of job B, and then their depdents as well until I find job A, which is not a very easy method nor reliable.
I checked the manual but could not find any direct option. Please do share if anyone knows any option or a workaround.
We can use command
PATH LEV *
to display all levels of predecessor and successors from ZEKE online panel of browsed event.

I am currently looking into SAS Viya 3.4 to replace SAS 9.4.
Now I was curious to see the possibilities of the Environment Manager in scheduling Jobs and mantaining and creating Job flows. However, I noticed that I could only Drag and Drop Jobs in a flow and connect them with very few configurable options. Also as a trigger to start a Jobflow I was only able to select a time event. I am wondering if there are other trigger types to choose from. Like a Job will be triggered if a specific table exists or a file exists [or ...]. Neither did I see the possibility to trigger/start a job based on the return code of the previous job.
Also it does not seem to be smart enough to make sure two jobs don't access a library with write access at the same time.
I can't see how SAS Viya could replace a Job Orchestration Tool. However, I feel like the tool was built to replace such an Orchestration Tool. Did I miss something or is it just not possible to do so with the Environment Manager in SAS Viya?
Any help/insights is highly appreciated. I already searched through the documentation but could not find anything.. Maybe I was just looking at the wrong place?
Why 3.4 and not 3.5 (or Viya 4)?
If you want to use Viya with your own Job Orchestration software you can consider this tool (built by my team): https://cli.sasjs.io/job/
We deployed it on Jenkins for this customer: https://www.sas.com/en_us/news/press-releases/2021/july/sas-partnership-with-lloyds-list-intelligence.html
I'm just wondering whether its possible for a single Job_instance in spring Batch to have multiple Job_execution if so can anyone please explain the process? And also for step_execution please !
Yes, a job instance can have multiple job executions. The typical use case is when a job instance has a first execution that fails, and a second (or subsequent) execution that succeeds.
This is explained in details with concrete examples in the Domain language of Batch section of the reference documentation.
In Talend Open Studio, how do I execute only one of my components? If I click Run, all active components will run. So far the only way I know to execute a single component is to deactivate all others in the Job.
How can I execute one component or subjob without having to deactivate all the other components in the job?
Well, I'm afraid you can't.
Two possible solutions :
Deactivating unwanted components / subjobs (like you already stated)
Decompose your job into multiple jobs. This may give you more flexibility. You can then use the tBufferOutput component to pass information from the child job to his parent.
I'm working on a project with Quartz and has been a problem with the dependencies with jobs.
we have a setup where A and B aren't dependent on eachother, though C is:
A and B can run at the same time, but C can only run when both A and B are complete.
Is there a way to set this kind of scenario up in Quartz, so that C will only trigger when A and B finish?
Not directly AFAIK, but it should be not too hard to use a TriggerListener to implement such a functionality (a TriggerListener is run both a start and end of jobs, and you can set them up for individual triggers or trigger groups).
EDIT: there is even a specific FAQ Topic about this problem:
There currently is no "direct" or "free" way to chain triggers with
Quartz. However there are several ways you can accomplish it without
much effort. Below is an outline of a couple approaches:
One way is to use a listener (i.e. a TriggerListener, JobListener or
SchedulerListener) that can notice the completion of a job/trigger and
then immediately schedule a new trigger to fire. This approach can get
a bit involved, since you'll have to inform the listener which job
follows which - and you may need to worry about persistence of this
information. See the listener
org.quartz.listeners.JobChainingJobListener which ships with Quartz -
as it already has some of this functionality.
Another way is to build a Job that contains within its JobDataMap the
name of the next job to fire, and as the job completes (the last step
in its execute() method) have the job schedule the next job. Several
people are doing this and have had good luck. Most have made a base
(abstract) class that is a Job that knows how to get the job name and
group out of the JobDataMap using pre-defined keys (constants) and
contains code to schedule the identified job. This abstract Job's
implementation of execute() delegates to an abstract template method
such as "doWork()" (where the extending Job class's real work goes)
and then it contains the code for scheduling the follow-up job. Then
they simply make extensions of this class that included the work the
job should do. The usage of 'durable' jobs, or the overloaded
addJob(JobDetail, boolean, boolean) method (added in Quartz 2.2) helps
the application define all the jobs at once with their proper data,
without yet creating triggers to fire them (other than one trigger to
fire the first job in the chain).
In the future, Quartz will provide a much cleaner way to do this, but
until then, you'll have to use one of the above approaches, or think
of yet another that works better for you.
Please assume the following scenario,
In a process flow there are three humanTask1, humanTask2, humanTask3; All three are assigned to same userA;
Now, assume there are two process instances (p1, p2) live. Each process instance can be in different tasklevel.
That is, for p1, task status are as, humanTask3-inprogress and for p2, humanTask1-inprogress
To display the tasks for this userA in a web page, I want them to be ordered as they appear in workflow design like,
p2-humanTask1
p1-humanTask3
taskService.getTasksOwned() may not return the tasks list in this order.
How do I ensure the tasks are displayed in this sequence?
I am using jBPM 5.3; LocalTaskService;
AFAIK, there is no out-of-the-box solution for this. You will have to decide your own order and then apply it whether by ordering the result of taskService.getTasksOwned() or by creating and executing a customized version of the query that taskService.getTasksOwned() is using.
Hope it helps,
