Hello, I am new to systemd init system as well as to fresh installed Fedora 23 Server, and I would like to put a question related to 'systemd (user)' and '(sd-pam) (user)' processes invoked under each and every one user's login shell. The first process is '/usr/lib/systemd/systemd --user' with PPID=1 and the second is its child process '(sd-pam)'.
What do these processes exactly do and why does my Oracle 12c database instance (started by 'oracle' user) always crash (silently shutdown by itself) WITHOUT these processes (or if they are killed)? When it happens, the database instance is down, and the oracle alert.log shows semaphore memory corruption: ORA-27300: OS system dependent operation:semctl failed with status: 22 ORA-27301: OS failure message: Invalid argument ORA-27302: failure occurred at: sskgpwrm1 ORA-27157: OS post/wait facility removed ORA-27300: OS system dependent operation:semop failed with status: 43 ORA-27301: OS failure message: Identifier removed ORA-27302: failure occurred at: sskgpwwait1 ksmsdes: Error destroying SGA Instance termination got error 27120 from SGA destruction. If these processes are active for 'oracle' user, Oracle instance never crashes. Thank you very much. _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
