Changes to database shutdowns during reboots on Linux (11g vs 12c) and Oracle Restart
It seems that when doing a reboot "shutdown -r now" on Linux hosts with 12c that we no longer get a message "Shutting down instance (abort)" in the alert log. We will sometimes get no message at all but just a message saying the instance has started: "Starting ORACLE instance (normal) (OS id: 4393)". Other times we get a message "Instance terminated by USER, pid = 23552 " but again no message saying the instance was shutdown. (Note: we are using Oracle Restart to manage the start/stop of the database. Some databases have ASM and some do not.)
Is this new functionality in Oracle? There's this note:
