New Release

Oracle ships JRockit Mission Control 4.1

Chris Mayer

Could it be a launchpad towards further JDK 7 support?

Oracle’s tool suite control centre, that monitors, manages, profiles, and covertly eliminate memory leaks on any JVM has recieved a huge renovation, as the company gears towards a revolutionary voyage into the depths of Java 7.

This is the first minor update since 2010’s 4.0.1, but with the name JRockit Mission Control, it would have to be as cohesive at co-ordinating as a NASA hub, and offer a plethora of vital tools. Well, JRockit Mission Control 4.1 certainly ups the ante with new features such as:

  • Support for Oracle JDK 7 in the shape of Java SE 7 and also the added bonus of local management for Hotspot JDK 1.6 and beyond.
  • Support for new platforms including Mac OS X and Solaris
  • No longer in the shadows, Eclipse (3.7) Indigo and later versions can be run on Mission Control.
  • Support for Associating JRockit Flight Recorder File with the JRockit Mission Control Client on
  •  Windows. The files with the .jfr extension are opened in the JRockit Mission Control client by default when you run the following command:

product_install_dirbinjrmc.exe -open recording.jfr

  • The new DTrace Plug-in is available through the update site

  • Enhancements in Management Console such as improved file resource operations in the Eclipse environment and zooming capability for charts.
  • Flight Recorder gets new features such as a better GUI editor, the Thread graph renders thread transition information with improved selection and zooming.

Markus Eisele details these improvements much further in his blog. Oracle say that in the future  they are focusing on support for JDK 7 and the converged HotSpot/JRockit JVM. The product will be renamed Java Mission Control as of the 5.0 release. But for now, you download it at Oracle’s website, fortunately with some helpful guides to initiate liftoff.
