Assuming I understand what you are asking, if you're using Linux you could
wrap the java executable in a script on the server where you want to add
the extra parameters, e.g. something like:

mv /usr/bin/java /usr/bin/java.orig

cat > /usr/bin/java <<EOF
#!/bin/sh

/usr/bin/java.orig <my-debug-params> $*
EOF

chmod +x /usr/bin/java
