Java code to access the shared heap
Hi
Help needed and forgive me as I dont know Java so please bare with me.
I have searched this site and google but was unable to locate the information I need.
An application that we use - is based on java and stores some performance counters etc internally in the shared JVM. They are not held in an oracle db etc
What I want to be able to do is access the shared area in JVM and write out the contents, I am not 100% sure how the counters are stored etc so I would need to access the entire JVM memory and write it to a file on the unix filesystem assuming thats even possible..
Can you help?
Server information:
java version "1.4.2_10"
Solaris 10

I have one Java application installed in my Solaris system. Is there a way to find out the heap memory allocated size/used size/free size for the particular Java process?
If anyone knows the command, please let me know. Even I appreciate if I have any scripts to find out the same.

airport-config
AIRPORT-CONFIG(1) General Commands Manual AIRPORT-CONFIG(1) NAME
airport-config - Configurator for the original Apple AirPort Base Station ("Graphite") and the Lucent RG-1000 base station SYNOPSIS
airport-config DESCRIPTION
airport-config allows you to manage your AirPort base station, just like the AirPort software on Mac OS X. OPTIONS
airport-config accepts no command-line options. airport-config is a wrapper script around the AirportBaseStationConfigurator.jar jar file located in /usr/share/java/airport-utils. You can set the JAVACMD environment variable to use a specific JVM instead of the one chosen by the wrapper script. Set the DEBUG environ- ment variable to 1 to get the debug output from the wrapper script. ENVIRONMENT VARIABLES
DEBUG Set this variable to 1 to get the debug output from the wrapper script. JAVACMD The full path to the Java Virtual Machine to use. By default, the wrapper uses JAVACMD; if it is not set, it looks for JAVA_BINDIR/java, then for JAVA_HOME/bin/java before looking for a java executable in the PATH. In the latter case, the JVM used can be configured using the Debian alternatives system (see update-alternatives(8)). JAVA_HOME The full path where your JDK/JRE is installed. JAVA_BINDIR The full path to the directory where the java executable is located. JAVA_ARGS Extra command-line arguments to be passed to the Java Virtual Machine. AUTHOR
