[Mageia-dev] systemd and non-systemd services question

[Frank Griffin]

I have a cauldron system with the Oracle Express Edition (oracle-xe) RPM 
installed.  This has worked nicely in the past, with the simple change 
that the /etc/init.d/oracle-xe script needs to have LSB headers added.

I don't start the DB automatically at boot, but only when I need it for 
testing.  Based on the creation date of the files in its log directory, 
the last time it started was Aug 3.

The database no longer starts.  Running the sysv script produces the 
message "Starting oracle-xe (via systemctl)", and produces no errors, 
but nothing happens.  "systemctl list-units | grep oracle" shows the 
status of oracle-xe.service as "loaded active exited", but no Oracle log 
file is created.  Moreover, there is no oracle-xe.service file anywhere 
on my root partition.

Issuing "systemctl start oracle-xe.service" issues no output. Running it 
under strace shows an execve for /bin/systemctl, and later on an execve 
for /usr/bin/systemd-tty-ask-password-agent, but very little else, and 
nothing that even hints at actually trying to execute any oracle code.

It seems like sometime after Aug 3 systemd changed in some way as to 
cause the failure.  The system was built (and the oracle-xe rpm 
installed) on Aug 2, and never gets touched after install (and the 
addition of LSB headers).   I haven't had to start it for a while, so I 
can't get it more precise than that.

Any idea how to diagnose this ?  Does systemd keep logs anywhere ?
