Debayan OSAD and the related packages come from the spacewalk repo, not the RHEL repo. The details below may help:
By default, the rhnsd daemon on a client system connects to the Spacewalk server every four hours (see /etc/sysconfig/rhn/rhnsd) and performs any updates or actions that have been scheduled. If you install the OSA daemon, you can apply updates and actions to client systems immediately from the Spacewalk server. osa-dispatcher Server-side service written in Python that determines when an osad client instance needs to be pinged or run rhn_check and sends a message telling them to do so. Open Source Architecture Daemon (OSAD) Client-side service written in Python that responds to pings and runs rhn_check when told to by osa-dispatcher. Install OSAD and related RHN/Spacewalk packages # yum -y install osad rhncfg rhncfg-actions rhncfg-client Spacewalk Actions Control - Enable Scheduled Actions # rhn-actions-control --enable-all Start OSAD # systemctl start osad.service Enable OSAD # systemctl enable osad.service OSAD Log File /var/log/osad See official documentation, at the following link, for more details: https://github.com/spacewalkproject/spacewalk/wiki/OSADSetup Regards Phil From: spacewalk-list-boun...@redhat.com <spacewalk-list-boun...@redhat.com> On Behalf Of debayan.mukher...@accenture.com Sent: 03 April 2019 12:32 To: spacewalk-list@redhat.com Cc: Lingayya, Shanker <shanker.linga...@accenture.com> Subject: Re: [Spacewalk-list] [External] Re: Need to know about spacewalk internal architecture and why spacewalk is taking time to deploy scheduled actions Hi James and others, 1.

Tried decreasing the value in /etc/sysconfig/rhn/rhnsd and it is not permitted to go below 60minutes. (https://access.redhat.com/solutions/92343). Is there any other solution to decrease the value (for syncing the scheduled actions in spacewalk)? Thanks!

On the clients change the value inside /etc/syscon/rhn/rhnsd To something like 15 minutes, I have my clients checking in every 40 minutes instead of the 240 minutes Hopefully that helps Thanks James Hibberd • Proact IT UK Technical Support Consultant m: +447 808 611 011<tel:+447%20808%20611%20011> jhibb...@proact.co.uk<mailto:jhibb...@proact.co.uk> | www.proact.eu<https://urldefense.proofpoint.com/v2/url?u=http-3A__www.proact.eu_&d=DwMFaQ&c=eIGjsITfXP_y-DLLX0uEHXJvU8nOHrUK8IrwNKOtkVU&r=kjYgKXRvPKJ-1Spwl9FaKBV5WMz2rUyGBr-Fiqe550E&m=APnqXKPsyWjgg1vpBLNUul_7Na6qQMvIgpFNkFJdMsI&s=eliLRYYiLKuWVkI2EbKEAIVKF3HmB3sf3sTFzGd_Xuo&e=> Grayson House • Venture Way • Chesterfield • S41 8NE • United Kingdom ‑ Delivering Business Agility ‑ [SIEM PoC]<https://urldefense.proofpoint.com/v2/url?u=https-3A__www.proact.eu_en_wp-2Dcontent_uploads_sites_2_2019_03_SIEM-2DPOC-2DA5-2Dflyer-5Fonline-2D1.pdf-3Futm-5Fsource-3Demail-2520signature-26utm-5Fmedium-3Dbanner-26utm-5Fterm-3D-26utm-5Fcontent-3D-26utm-5Fcampaign-3Duk-5Fsiem-2Dpoc&d=DwMFaQ&c=eIGjsITfXP_y-DLLX0uEHXJvU8nOHrUK8IrwNKOtkVU&r=kjYgKXRvPKJ-1Spwl9FaKBV5WMz2rUyGBr-Fiqe550E&m=APnqXKPsyWjgg1vpBLNUul_7Na6qQMvIgpFNkFJdMsI&s=qJLaB8mmZMwn5aILcWhLcpI0Mx2Ahl15v_EKOXxeR1o&e=> This email and its attachments may be confidential and are intended solely for the use of the individual to whom it is addressed.

I have recently installed spacewalk on RHEL 7.6 as server configuration management tool. I have few doubts as follows: 1. Could you please let me know how Spacewalk pushes packages to the clients? a. Does Spacewalk store the packages on the Spacewalk server and push these packages to Client? The default is to setup a software repository so that packages can be pulled from the spacewalk server. OR b. Does Spacewalk send the command to the client servers and client servers will then reach out to internet and download the packages? This depends on your setup, you can enable OSAD<https://urldefense.proofpoint.com/v2/url?u=https-3A__eur03.safelinks.protection.outlook.com_-3Furl-3Dhttps-253A-252F-252Fwww.google.com-252Furl-253Fsa-253Dt-2526rct-253Dj-2526q-253D-2526esrc-253Ds-2526source-253Dweb-2526cd-253D1-2526cad-253Drja-2526uact-253D8-2526ved-253D2ahUKEwi-2D2JLN0LHhAhUu2FkKHTiQAbIQFjAAegQIBBAB-2526url-253Dhttps-25253A-25252F-25252Fgithub.com-25252Fspacewalkproject-25252Fspacewalk-25252Fwiki-25252FOsadHowTo-2526usg-253DAOvVaw3nli6m6b8TG4JwyRQeymfF-26data-3D02-257C01-257C-257Cf5f103c625ec474b160208d6b779f9a8-257Cc047d5c1d2a6484dae6eec2bce85d023-257C0-257C0-257C636898131854267343-26sdata-3D-252BVePq5h6iAwFpwrrTFUzPHX7pYNpRdG4o8wg3kh0uo4-253D-26reserved-3D0&d=DwMFaQ&c=eIGjsITfXP_y-DLLX0uEHXJvU8nOHrUK8IrwNKOtkVU&r=kjYgKXRvPKJ-1Spwl9FaKBV5WMz2rUyGBr-Fiqe550E&m=APnqXKPsyWjgg1vpBLNUul_7Na6qQMvIgpFNkFJdMsI&s=56DmmPhFlDLHSnzdFA1NFr7pFXkonyXEBB7ODYJcN1I&e=> to change how and how often the spacewalk server contacts the clients and perform various management operations (to include patch management, configuration, and etc.). 1. Does Spacewalk support Primary/secondary site (Microsoft SCCM Architecture) for package redistribution to clients. i.e. If I have a remote Datacenter, instead of pushing packages to individual clients, can we have a Spacewalk secondary site that will get the package from master and redistribute the packages to clients locally? Yes, you can configure multiple spacewalk servers (i.e. you can have a single master (primary) spacewalk server with several spacewalk proxies that reach out to several different client environments). A good reference resource https://docs.oracle.com/cd/E92593_01/E85211/html/swk24-arch.html<https://urldefense.proofpoint.com/v2/url?u=https-3A__docs.oracle.com_cd_E92593-5F01_E85211_html_swk24-2Darch.html&d=DwMFaQ&c=eIGjsITfXP_y-DLLX0uEHXJvU8nOHrUK8IrwNKOtkVU&r=kjYgKXRvPKJ-1Spwl9FaKBV5WMz2rUyGBr-Fiqe550E&m=APnqXKPsyWjgg1vpBLNUul_7Na6qQMvIgpFNkFJdMsI&s=RBmlnmoXZG6OUw-7QpAX_y66PP0rQUbS4aGE4CGUBLo&e=> 1. I see that scheduled activities (like reboot, patching, etc) are taking a lot of time (1.30 hours delay) and crosses the scheduled window. However, I see that as a workaround when I run “rhn_check” command on the client manually, deployment status on Spacewalk changes to succeeded. . That’s because of how your initial setup is configured, if you want faster response to queued jobs then look into option (1.b), otherwise check taskomatic to make certain that you don’t have queued jobs causing delays and setup a cron on the client to complete queued jobs (from the spacewalk server). https://www.redhat.com/archives/spacewalk-list/2015-January/msg00173.html<https://urldefense.proofpoint.com/v2/url?u=https-3A__www.redhat.com_archives_spacewalk-2Dlist_2015-2DJanuary_msg00173.html&d=DwMFaQ&c=eIGjsITfXP_y-DLLX0uEHXJvU8nOHrUK8IrwNKOtkVU&r=kjYgKXRvPKJ-1Spwl9FaKBV5WMz2rUyGBr-Fiqe550E&m=APnqXKPsyWjgg1vpBLNUul_7Na6qQMvIgpFNkFJdMsI&s=q1AWCr5nPvdecuH01c7miEe_9F-lbvDb6Vpcy7rvHmg&e=> Thanks!
