Configure an EM4J-Enabled tc Runtime Instance

The tc Server elastic-memory template installs a Java library (balloon.jar) and a native library ( It sets up logging for EM4J and modifies the Java command line in the following ways:

To modify these values, edit the CATALINA_BASE/bin/ file, which constructs the JAVA_OPTS environment variable passed to the Java command line when the tc Runtime instance starts up.

The elastic-memory template sets the logging level for EM4J to the INFO level by default. You can edit CATALINA_BASE/conf/ to set a different logging level.
