Description Tom McKay 2012-09-17 15:14:05 EDT
The katello-jobs service has an option in /etc/sysconfig/katello KATELLO_JOB_WORKERS to control the number of threads. This option needs to be exposed via katello-configure.

As a side note, I see the following in that file

# number of katello-job service background workers

# additional katello-job service options for delayed_jobs
#KATELLO_JOB_WORKERS=-m -p katello

which seems incorrect. Is that second one supposed to be named differently? It too needs to be settable via katello-configure
Comment 2 Lukas Zapletal 2012-09-18 03:39:30 EDT
Yeah it's a typo. The latter should be: KATELLO_JOB_PARAMS. I can add that to katello-configure.
Comment 3 Lukas Zapletal 2012-09-18 04:35:10 EDT

Please give it QA ack, easy to verify.

Doc text:

New katello-configure installer option called --job-workers which defines how many background job workers should CFSE use for promotions and other background tasks (excluding synchronization jobs). Default is 1.

FYI you can do review of all installer options reading man katello-configure.
Comment 6 Garik Khachikyan 2012-09-18 05:52:30 EDT

and how to check the running threads count for background jobs? what/where to grep please?
Comment 7 Garik Khachikyan 2012-09-18 06:00:00 EDT
assigning Hayk H. as QE contact.
Comment 8 Lukas Zapletal 2012-09-18 07:57:49 EDT
QA: grep KATELLO_JOB_WORKERS /etc/sysconfig/katello
Comment 9 Garik Khachikyan 2012-09-18 08:05:17 EDT
any other way to detect that like: there are 2 parallel jobs working, grep of the `ps` or ?
Comment 10 Lukas Zapletal 2012-09-21 04:45:43 EDT
# ps axu | grep delayed_job
katello   4998  0.0  9.6 308128 173116 ?       S    Sep20   0:45 katello/delayed_job                             
katello   4999  0.0  6.3 307144 114816 ?       S    Sep20   0:00 delayed_job_monitor                             
root     19127  0.0  0.0   6380   684 pts/0    S+   10:44   0:00 grep delayed_job

Each ONE worker has TWO processes, one is called delayed_job_monitor and one katello/delayed_job.
Comment 13 Hayk Hovsepyan 2012-10-02 09:11:52 EDT
Verified on revision:

Now if we configure "job-workers=2" it runs 2 instances of both "delayed_job*" jobs.
