JavaRuntime
JavaRuntime refers to Java Runtime Environment (JRE). It is required to run Java applications and applets.
APM monitors JRE applications.
 Java Management Extensions—JMX, is a Java technology that supplies tools for managing and
monitoring applications, system objects, devices and service oriented networks.
 Remote Method Invocation—RMI, provides a model for distributed computation with Java objects.
These objects can be new Java objects or simple Java wrappers around an existing Application
Programming Interface (API).
 Java Naming and Directory Interface—JNDI, part of the Java platform, providing applications
based on Java technology with a unified interface to multiple naming and directory services. The
commonly used JNDI name is jmxrmi.
Configuring JavaRuntime to support RMI access
The APM monitors the JRE applications by obtaining monitor index data through RMI access. By default,
most JRE applications do not provide RMI access. Operators must modify the JRE start script to support
RMI access. This section describes how to configure application with JRE to support RMI access. The
applications with JRE include Tomcat server and IMC.
1. Use a text editor, such as a Notepad and vi, to open the start script of the JRE application.
For Tomcat with JRE
 In Windows operating system: <Tomcat installation path>\bin\catalina.bat
 In Linux/Unix operating system: <Tomcat installation path>/bin/catalina.sh
For IMC with JRE
 In Windows operating system: <IMC installation path>\Client\bin\startup.bat.
 In Linux/Unix operating system: <IMC installation path>/Client/bin/startup.sh.
2. Add the following text to the script:
set JAVA_OPTS=%JAVA_OPTS% -Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=1099 -Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
Parameter description:
 Dcom.sun.management.jmxremote.port=1099—1099 is the listening port. It can be another
port, but cannot conflict with other services.
 Dcom.sun.management.jmxremote.ssl=false—false indicates that no SSL connection is needed
for remote RMI access.
 Dcom.sun.management.jmxremote.authenticate=false—false indicates that no authentication
is needed for remote RMI access. For information about enabling authentication, see the Java
document.
 No carriage returns can be included.
 For IMC, this text should be in front of the part "%IMC_HOME%\bin\bootstrap.jar" start.
3. Save the script and restart the JRE application.
