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.

NAME
rmiregistry - Java remote object registry
SYNOPSIS
rmiregistry [ port ]
DESCRIPTION
The rmiregistry command creates and starts a remote object registry on the specified port on the current host. If port number is omitted,
the registry is started on port 1099. The rmiregistry command produces no output and is typically run in the background. For example:

A remote object registry is a bootstrap naming service that is used by RMI servers on a host to bind remote objects to names. Clients can
then look up remote objects and make remote method invocations.
The registry is typically used to locate the first remote object on which an application needs to invoke methods. That object in turn pro-
vides application-specific support for finding other objects.
The methods of the java.rmi.registry.LocateRegistry class are used to get a registry operating on a particular host or host and port.
The URL-based methods of the java.rmi.Naming class operate on a registry and can be used to look up a remote object, bind a simple (string)
name to a remote object, rebind a new name to a remote object (overriding the old binding), unbind a remote object, and list the URLs bound
in the registry.
OPTIONS
The following option is supported:
-Joption Used in conjunction with any java option, this option passes option (no spaces between -J and option) on to the java inter-
preter.
