Re: systemd issues

Hi!

I have tested it on OL 7.6 but OL 7.6 still supports sysvinit emulation and the old scripts work fine. I had the service file in /etc/systemd/system and I copied dbstart and dbshut into /usr/local/bin.  I created the environment file /etc/default/oracle. That has worked if there was only a single home. The trick was to create two services, not one. One would fire on startup, the other one on shutdown. However, I was never able to resolve the situation with more than one Oracle home. I finally gave up because sysvinit emulation doesn't seem to be going away anytime soon. It is not removed from the upcoming RH 8:

https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8-beta/html/8.0_beta_release_notes/removed_functionality

That should give me another 5 years or so of sysvinit bliss. Hopefully, until then, the people will come to their senses and document the systemd a bit better, so that administrators can write service scripts. The main problem with systemd is that it is developing fast and there is no documentation for it. I am not sure what kind of magic was used to persuade SuSE, Canonical, Red Hat and GNU Foundation to switch to systemd, but it must have been a business decision. If only one of the above has remained faithful to the good, old sysvinit, it would have swept the other ones off the market. I am not a fan of systemd and will not adopt it unless I have to. People are coming to their senses. Brtfs, once touted as the best thing since sliced bread, is fading away into oblivion.
