I installed JDeveloper 11g Release 2 (18.104.22.168.2) Studio - 22.214.171.124
I run the Launch Oracle JDeveloper 11g, and then I got this error:
"Unable to create an instance of the java virtual machine"
Any reason why you don't use jdev 126.96.36.199.0 and instead try the older version 188.8.131.52.0?
Anyway, uninstall the version, delete the folder where you have installed the old version. Then install again (I would recommend 184.108.40.206.0).
If this doesn't help. you need to give us more information about your OS and the hardware your use.
I get this error message all the time. Check to see if you have an open MS Word, MS Excel or Outlook with the ADF Component loaded in it. By closing the offending MS application, JDeveloper loads. So annoying.
I installed Jdeveloper on a Windows XP PC.
The processor is AMD Phenom II X4 B93 (quad processor)
3GB of RAM
I managed to make it work by updating
c:\Oracle\Middleware11120\jdeveloper\ide\bin\ide.conf to be
Instead of using 800M, I reduce it to 640M.
I still have 2G of available memory, so why it cannot be 800M?
Let me provide a little more information. I installed the ADF Data visualization components for MS Office - that's when I started to see this error message. I also changed my ide.conf settings to increase memory - but that didn't make any difference. I'm running Windows 7 (64-bit) on a 4Gb Dell Notebook. I don't get the error so long as I'm not running any MS Office programs.
Well, the mx option is only one part of the memory pool used by the jvm. So it might be that you are running out of memory with the bigger value. Even if you see more memory in total, there might not be enough memory in one peace to fulfill the request.
