Which method is common for Oracle database and listener auto startup on Linux?

Add a dbora file and run it by chkconfig
(Ref: http://www.oracle-base.com/articles/linux/AutomatingDatabaseStartupAndShutdownOnLinux.php)

Or

Append a line in /etc/rc.d/rc.local to call the dbstart by oracle OS user
(Ref: https://www.linuxquestions.org/questions/linux-software-2/auto-start-script-for-oracle-92207/)

I don't know which method is reliable and safer. Thanks!

Both are reliable

Check Script for automatic startup on boot.

Most websites tell us to create a oratab file and set to runlevel, but I just find adding entries in rc.local easier.

Thank you!

You do realize what the oratab file does...right ?

As far as I know, dbora is used to start and stop database/listener by "oracle" user, right?

But I'm not sure the about the run level and Oracle.

Are you talking about dbora or oratab?

oratab is a file showing a flag for doing auto db start or not.

dbora is a script file to start the db and listener in certain runlevel, isn't it?

Correct. oratab is referenced by dbstart, which depending on how you have configured dbora, can be called by dbora.

Since you mentioned "create a oratab file and set to runlevel", I just wanted to ensure the distinction between all those files.

I found most documents use the method (/etc/init.d/dbora) to start/stop the database.

According to my limited knowledge, I guess the dbora allows the Oracle database to be shut down in a proper procedure when the system runlevel is going into reboot/halt level?

However, setting command in rc.local simply calls the startup. When server is reboot/halt, those Oracle processes will be killed (similar to shutdown abort). This may cause data lose and trigger a recovery process in the next startup.

Am I right?

Correct, appropriate shutdown is also important. Check Auto start/stop of Oracle on Linux for a script example.
