How start or stop is passed to the dbora script in the symbolic links?

Hi,

I follow the steps in http://download.oracle.com/docs/html/B10812_06/chapter2.htm to automate startup and shutdown of Oracle database through the script file dbora.  The script file dbora takes at least one parameter start or stop.  The last step of setup is to create symbolic links to the dbora script in the appropriate run-level script directories, as follows for Linux platform:

Linux

# ln -s /etc/init.d/dbora /etc/rc.d/rc3.d/K01dbora # ln -s /etc/init.d/dbora /etc/rc.d/rc3.d/S99dbora # ln -s /etc/init.d/dbora /etc/rc.d/rc5.d/K01dbora # ln -s /etc/init.d/dbora /etc/rc.d/rc5.d/S99dbora
