"systemctl stop tsminst1" is not a kill. That's a service command to tell the application it manages to shut down gracefully.
>From the KC: https://www.ibm.com/support/knowledgecenter/SSEQVQ_8.1.0/srv.install/t_srv_startsrv_autolnx-linux.html 6. To start or stop the server, issue one of the following commands: To start the server: service tsminst1 start To stop the server: service tsminst1 stop >From the /etc/init.d/tsminst1 wrapper script, it does do a kill command, but without any signal, which means it defaults to -15 (SIGTERM). That sends a message to the process to shutdown gracefully. - Thanks, Marc... ________________________________________________________ Marc Lanteigne Spectrum Protect Specialist AVP / SRT 416.478.0233 | marclantei...@ca.ibm.com Office Hours: Monday to Friday, 7:00 to 16:00 Eastern Latest Servermon for Spectrum Protect: http://www-01.ibm.com/support/docview.wss?uid=swg21432937 Performance Mustgather for Spectrum Protect: http://www-01.ibm.com/support/docview.wss?uid=swg22013355 Spectrum Protect Blueprint: https://ibm.biz/BdHc6b Follow me on: Twitter, developerWorks, LinkedIn -----Original Message----- From: Zoltan Forray <zfor...@vcu.edu> Sent: Monday, March 11, 2019 01:52 PM To: ADSM-L@VM.MARIST.EDU Subject: Re: [ADSM-L] best way to avoid long rollback Out of curiosity, why do you do a "systemctl stop tsminst1" (which if I recall does a kill) vs just HALT the ISP server immediately after the DB backup finishes? Our patching takes about the same time (we do it monthly) since the IBM lin_tape drivers have to be removed before kernel patching and then reinstalled afterwards which adds to the time.
