First of all oracle should be the first one to shutdown before ANY of the other OS services. If there is an oracle dependancy to any of the services that shutdown already, oracle will either hang or crash.
Then if oracle is in the middle of a large job, it will not shutdown until the big job is finished or you force it to shutdown with a "shutdown abort" method which is brute force and needs special treatment. You or your DBA should connect to oracle and see what it is doing in the database to determine why it is not shutting down.

[Bill Hassell]

The ordering of Oracle shutdown very wrong. As mentioned above, all applications that depend on Oracle must be stopped first, then Oracle shutdown, then the rest of the items. This is controlled by the symlinks in /etc/rc*.d and can be seen (in shutdown order by init state) with the command:

ll /sbin/rc?.d/K*

The "K" links point to the shutdown scripts in /sbin/init.d and the first item in the list will be the first to be shutdown when changing to the specified init state. So the number should be low (like K002oracle) in rc2.d. The "K" specifies a stop link and the 3 digits will order the steps regardless of the name of the script.

This is opposite to "S" links which are run at startup. The highest numbers (S998oracle) are run last during bootup.
