1. Stop all running ColdFusion services.
2. Locate the Java configuration file jvm.config. This can be found in the following location:
   
   

   Windows:	C:\CFusionMX7\runtime\bin
   Unix standalone:	/opt/cfusionmx7/bin/
   Unix multi-instance:	/opt/jrun4/bin/

3. Make a copy of this file, and store the copy somewhere on your disk. In case of problems, you can restore the copy to this location.
4. Open this file in a text editor (e.g. Notepad).
5. Locate the line java.args. These are the settings used to start the Java Virtual Machine, in which ColdFusion runs.
6. Remove this option:
   
   -XX:+UseParallelGC
   
   
7. Add these options. All options must be on the same line. Be careful not to introduce any line breaks:
   
   -Djava.compiler=NONE -Xnoagent -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8000
   
   
8. All options must be on the same line. Be careful not to introduce any line breaks.
   The following line is an example of a complete java.args parameter line:
   
   

   java.args=-DJINTEGRA_NATIVE_MODE -DJINTEGRA_PREFETCH_ENUMS
    -Xmx512m -XX:MaxPermSize=128m\-Dsun.io.useCanonCaches=false
    -Dcoldfusion.rootDir={application.home}/../ -Dcoldfusion.libPath={application.home}/../lib 
    -Djava.compiler=NONE -Xnoagent -Xdebug 
    -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8000 
    -Dcoldfusion.classPath= {application.home}/../../classes,{application.home}/../lib/updates,
    {application.home}/../lib/,{application.home}/../gateway/lib/,{application.home}
    /../wwwroot/WEB-INF/cfform/jars
