Setting JVM options

The preferred method of setting JVM options (including system properties and JVM flags) is via the SO_JAVA_OPTS environment variable. For instance:

export SO_JAVA_OPTS="$SO_JAVA_OPTS -Djava.io.tmpdir=/path/to/temp/dir"
./bin/startup

When using the RPM or Debian packages, SO_JAVA_OPTS can be specified in the system configuration file.
