can someone please tell what could be the possible reason for this job failure.

I have a list of processes triggered one after the other, in parallel. And, I need to know the exit code of all of these processes when they complete execution, without waiting for all of the processes to finish.
While status=$?; echo $status would provide the exit code for the last command executed, how do I know the exit code of any completed process, knowing the process id?
You can do that with GNU Parallel like this:
parallel --halt=now,done=1 ::: ./job1 ./job2 ./job3
The --halt=now,done=1 means halt immediately, as soon as any one job is done, killing all outstanding jobs immediately and exiting itself with the exit status of the complete job.
There are options to exit on success, or on failure as well as by completion. The number of successful, failing or complete jobs can be given as a percentage too. See documentation here.
Save the background job id using a wrapper shell function. After that the exit status of each job can be queried:
#!/bin/bash
jobs=()
function run_child() {
"$#" &
jobs+=($!)
}
run_child sleep 1
run_child sleep 2
run_child false
for job in ${jobs[#]}; do
wait $job
echo Exit Code $?
done
Output:
Exit Code 0
Exit Code 0
Exit Code 1
I am moving existing manual shell scripts to execute via autosys jobs. However, after adding exit 1 for each failed autosys job; it is not failing and autosys shows exit code as 0.
I tried the below simple script
#!/bin/ksh
exit 1;
When I execute this, the autosys job shows a success status.I have not updated success code or max success code in autosys, everything is default. What am I missing?
Difference between Batch Status and Exit Status in Spring Batch
From the Spring Batch documentation:
A BatchStatus object that indicates the status of the execution. While running, it's BatchStatus.STARTED, if it fails, it's BatchStatus.FAILED, and if it finishes successfully, it's BatchStatus.COMPLETED
The ExitStatus indicating the result of the run. It is most important because it contains an exit code that will be returned to the caller.
For more on the difference, see the section 5.3.2.1. Batch Status vs. Exit Status. You will find the explanation is quite good.
I've written some code that should run as a server and wrapped it with Daemons as Daemons.run('myserver.rb'). When I run it as ./daemon.rb start it works but it is not informative at all, i.e. if myserver.rb throws an exception I will not even know my server did not start, Daemons will exit with exit code 0. Is there any way to tell Daemons to return a non-zero exit code if the wrapped script fails to start? Or perhaps another way for me to know if my server started successfully?
try
d=Daemons.run('myserver.rb')
exit d.applications.length > 0 ? 0 : 1
When we kill a process in Windows with Task Manager End Process command, will the process still return an exit code? And if so, what exit code it returns? Thanks
In general, a process is terminated using TerminateProcess. The exit code is passed as a parameter to this method.
In the case of the task manager, the exit code is set to 1, but I don't know if it's documented anywhere.
Yes, it will return non-zero return code which will be wrapped in %ERRORLEVEL% variable.
