No need to uninstall anything.
Install the required oracle java using rpm.
Using alternatives command as superuser one can change the default java used.
Bare in mind, that perhaps some programs on the system rely on open java, so above change could affect those.
One could also download only required oracle java as compressed archive with all binaries and libraries required.
Create a user on the system which will utilize that java environment.
Unpack the archive under /opt/orajava (for instance)
As root, chown /opt/orajava to user created.
Setup required java options in user home directory profile file (JAVA_HOME etc.)
Configure kernel parameters for that user, depending on the application requirements/load (if applicable, defaults are often ok).
Above setup will have no effect on the system other then running new processes/code (load) under user created above and consuming disk space required.
Hope that helps
Regards
Peasant.

airport2-portinspector
AIRPORT2-PORTINSPECTOR(1) General Commands Manual AIRPORT2-PORTINSPECTOR(1)
NAME
airport2-portinspector - Port maps inspector for the Apple AirPort Extreme Base Station ("Snow")
SYNOPSIS
airport2-portinspector
DESCRIPTION
airport2-portinspector allows you to inspect the port maps used by the hosts associated with your base station.
OPTIONS
airport2-portinspector accepts no command-line options. airport2-portinspector is a wrapper script around the PortInspector.jar jar file
located in /usr/share/java/airport-utils.
You can set the JAVACMD environment variable to use a specific JVM instead of the one chosen by the wrapper script. Set the DEBUG environ-
ment variable to 1 to get the debug output from the wrapper script.
ENVIRONMENT VARIABLES
DEBUG Set this variable to 1 to get the debug output from the wrapper script.
JAVACMD
The full path to the Java Virtual Machine to use. By default, the wrapper uses JAVACMD; if it is not set, it looks for
JAVA_BINDIR/java, then for JAVA_HOME/bin/java before looking for a java executable in the PATH. In the latter case, the JVM used can
be configured using the Debian alternatives system (see update-alternatives(8)).
JAVA_HOME
The full path where your JDK/JRE is installed.
JAVA_BINDIR
The full path to the directory where the java executable is located.
JAVA_ARGS
Extra command-line arguments to be passed to the Java Virtual Machine.
