There are two ways of setting new Java Virtual Machine parameters:
On Mac OS X you can set or change existing parameters by editing the Info.plist file:
On Windows and Linux you can change or add new Java Virtual Machine parameters and Java system properties by editing the .vmoptions file associated with each application launcher. The file can be edited with any text editor (like Notepad).
For example the file oxygen 14.2.vmoptions is located in the same folder with the application launcher. If the file does not exist then you will have to create it.
On Windows Vista/7 you will first have to copy the oxygen 14.2.vmoptions file to a folder with write access (like your Desktop), modify it there with a text editing application (like Notepad) and then copy it back to the installation folder, replacing the original file.
If you start the application with the script oxygen.bat you have to add or modify the parameter to the java command at the end of the script.
For example to set the maximum amount of Java memory to 600 MB on Windows the -Xmx parameter must be modified like this:
java -Xmx600m -Dsun.java2d.noddraw=true ...
on Mac OS X the java command should look like:
java "-Xdock:name=Oxygen"\ -Dcom.oxygenxml.editor.plugins.dir="$OXYGEN_HOME/plugins"\ -Xmx600m\ ...
and on Linux the Java command should look like:
java -Xmx600m\ "-Dcom.oxygenxml.editor.plugins.dir=$OXYGEN_HOME/plugins"\
