Request stop in Rapidminer Server

AlphaPi

Hello everyone,

I was running a process in Rapidminer server. When i wanted to stop it, i pressed the "Request stop" button. But still, this process is encountered among the "Running" processes. How can i stop this process and delete it from the Executions tab?

Thanks in advance

Hi. Unfortunately there's currently no other way. Please ask your administrator to do those steps if you absolutely need it.

Hi icsdm217003! I assume that you're using our latest Server release 9.6? It's known that some executions keep appearing as running. This will be handled in the upcoming release by introducing a force stop option which will kill the executing Job Container forcibly. For now your only option is to restart the Job Container/Job Agent executing the Job. The job will be flagged as timeout if you do so. If not, you could jump into the underlying database, look for the job and change its state manually to STOPPED.

This is a potentially destructive operation, ensure that it's only affecting the one job you like to change the state of.

// Get all jobs in running state, but you probably only want the one ID from the job you like to stop
SELECT * FROM jobservice_job WHERE state = 'RUNNING';

// Use the ID column to update the state
UPDATE jobservice_job SET state = 'STOPPED' WHERE id = 'The-ID-You-Found-Out-In-The-Query-Above';

Hi aschaferdiek, I am using the server through the browser. Is there any solution, in this case?

Please note that the table name is jobservice_job and not jobservice_jobs

<i>rmsdb=> SELECT * FROM jobservice_job</i><br><i>jobservice_job&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; jobservice_job_context_in&nbsp;&nbsp;&nbsp;&nbsp; jobservice_job_error</i><br><i>jobservice_job_agent&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; jobservice_job_context_macro&nbsp; jobservice_job_log</i><br><i>jobservice_job_context&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; jobservice_job_context_out&nbsp;&nbsp;&nbsp; </i>

Yes, I'll adapt the original answer. Thanks for pointing that out.

I'd like to highlight that this introduces several problems when using an external message broker. It will mess up all the job agents. Therefore, the solution is purging the queue directly from the message broker. >>> https://activemq.apache.org/how-do-i-purge-a-queue

RM Server should have an option to Force Stop all enqueues messages (i.e. jobs), and this action should purge the queue in the external broker and at the same time update the DB.

As already mentioned, you need to shut down all Job Agents otherwise they keep sending updates.

Starting from 9.6 there's a 'purge queue' solution integrated into RapidMiner Server. https://docs.rapidminer.com/latest/server/configure/queues/index.html#purge-process-executions

9.7 includes a mechanism to force stop an execution.
