Local java processes are grayed when trying to connect via JMX

Question

I'm running a number of java processes on a windows XP professional machine. When i attempt to connect to these processes via a local JConsole the processes are grayed out.

However i can run the same processes on another machine and connect via a local JConsole on that machine.

Both machines are running java 1.6 version for the processes and jconsole.

Any ideas why these processes are grayed out?

Answer 1

I had the problem as described earlier, but was advised a simpler solution: just close all programs using Java ("IntelliJ IDEA", "SoapUI", etc. - to unlock the temporary folder) and then delete %TMP%\hsperfdata_<user.name> folder. Then, after opening any Java program, this folder will be recreated but this time with correct name (most likely %TMP%\hsperfdata_<User.Name>). And after that, local Java processes can be monitored through "JConsole" or "VisualVM" (now runs without starting error with a link to VisualVM: Troubleshooting Guide) again.

Answer 2

Change the name of the hsperfdata folder which for me was found at C:\Users\pmimgg0\AppData\Local\Temp\hsperfdata_pmimgg0 to match the User name found on task manager. Once I changed hsperfdata_pmimgg0 to hsperfdata_PMIMGG0 my local process was no longer greyed out on jconsole.
