i was excited to show some of my colleagues how great Java Mission Control is to debug, troubleshoot and monitor local and remote Java applications. On my OSX 10.9 laptop i installed the latest Oracle JDK 7, which now includes Java Mission Control with the JDK, and i expected to be able to type jmc on the command line. that didn't work and resulted in a command not found! OSX Finder wouldn't find jmc it either. i found a hint on an OTN community thread. the Java installer only put installation files in the obscure and hard to find /Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/ instead of also placing a shortcut in /usr/local/bin which should link to /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/jmc that should change when you use /usr/libexec/java_home. you can see the install location by running this command:
$ find /Library/Java -name jmc
/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/lib/missioncontrol/Java Mission Control.app/Contents/MacOS/jmc
the solution i chose was to create this executable file in /usr/local/bin/jmc
maybe it's because i had JDK 7 installed originally before Mission Control was included with it. i'm not sure, but i hope this helps someone else.
