JConsole location in Linux

Question

I am trying to run jconsole from my machine but I can't find the location of the .sh . I have tried finding it in different directories and setting JAVA_HOME to the jdk.

$which java
/usr/bin/java
$java -version
java version "1.7.0_51"
OpenJDK Runtime Environment (rhel-2.4.4.1.el6_5-x86_64 u51-b02)
OpenJDK 64-Bit Server VM (build 24.45-b08, mixed mode) 
$whereis java 
java: /usr/bin/java /etc/java /usr/lib/java /usr/share/java /usr/share/man/man1/java.1.gz

I looked in /usr/lib/jvm and I found

and in java-1.7.0-openjdk-1.7.0.51.x86_64/jre/bin/, I only found

..even though there are 200 files. How can I find and run jconsole?

Answer 1

jconsole is part of the Java SDK, it appears you only have the JRE installed.
