Ok. Note that what you are asking is not a tomcat-specific question, it is more 
of a
standard Java question.

You need to find the shell script that starts Tomcat on your system.
That is likely to be in the directory /etc/init.d, or /etc/init.d/rc2.d or 
similar.
In that script, you will find the line(s) that starts the JVM that runs tomcat.
(I cannot tell you what that is exactly, because I do not have a RHEL system 
available to
look at right now).
That script should have some internal variables, such as "JAVA_OPTIONS" e.g., 
which
contain the options used on the Java command-line.
That's where you must start looking, to make you modifications.

Note that this system startup/stop script is likely to be overwritten, whenever 
you
install an OS or Tomcat package update. So it would be better to do such 
changes in a
separate file, which is "called-in" when executing the script.
The startup script probably already references such separate files just for 
that purpose.
Look at (for example) any references to a directory like /etc/tomcat8 or
/etc/default/tomcat e.g.

I believe that the person responsible for the RH tomcat package is also on this 
list.
Maybe he can provide more detailed instructions as to how to do this correctly 
for that
platform.

Of course, you could also search Google for "red hat change tomcat java 
options", which
would have given everyone the nice and comforting feeling that you had "done 
your
homework" before coming here.
