Note is good. It says set the Xmx parameters only.
also update fnd_cp_services for opp
But note that:

Update the fnd_cp_services for opp as follows;

J:oracle.apps.fnd.cp.gsf.GSMServiceController:-mx3096m -XXtlasize1024k -XXlargeobjectlimit1024k

Also update the problematic concurrent program's arguments as;
-Xms2048M -Xmx3096M

Note that : different jvm versions uses different argument names for the same thing. You will see that some arguments become obsoleted when you use a higher level jdk..

Note that: The JVM used in EBS 12.2 was 32 bits. Even if the EBS is 64 bit, it uses 32 bit jvm for these processes.  The Java version used by OPP in this environment is 1.6.. So you may encounter errors if using the above params in 1.7. Note that -> these XX parameters are for Jrockit only.
