After ugrade to 12.2 scheduler jobs not start with non-default value of job_queue_processes

Hi,

we start observe very strange behavior of 12.2 job scheduler. On 11.2 we have job_queue_processes on 10 and jobs were executed according to schedule. After upgrade to 12.2 jobs stop working and solution is to increase a value of job_queue_processes idealy to default 1000.

Why?

Ok, I have 50 jobs in the database but they never run i one time, so I sized the job queue to 10. I though that if the job queue is "small" jobs will wait till any other finished and then the waiting job will be executed. But now no job runs.

Why?

Is there any difference between 11.2 and 12.2 scheduler behavior?

Howdy, Stranger!
