JDeveloper on 64-bit Windows7
For a lot of us the migration to Windows7 will be the first time we get easy access to a 64-bit desktop OS. One of the first things after an upgrade like that is to get your tools, like in my case JDeveloper, working again. First step is to download the jdevinstall jar, and the Sun JDK. The installation worked fine:
1 | java -jar jdevstudio11112install.jar |
Running JDeveloper on 64-bit JVM
Running JDeveloper with the 64-bit JVM resulted in an error:
1 2 3 | Unable TO launch the Java Virtual Machine located at path: C:\Java\jdk1.6.0_18\jre\bin\server\jvm.dll |
A solution is to use the 32-bit JVM. To do this change the SetJavaHome in thejdev.conf that is located in the {JDEV_HOME}\jdev\bin\jdev.conf.
1 | SetJavaHome C:\Java\jdk1.6.0_18_x86 |
Where the jdk1.6.0_18_x86 is a 32-bits JVM version.
What about the performance? Is it faster than the 32bit Win7?
Thanks
Not sure, haven’t compared it yet. I’ll see if I can find a collegue tomorrow running 32bit win7. If I do i’ll post an update.
Thanks a lot !
I assume the performance of Jdeveloper on 64 bit Wind 7 should be the same as 32 bit Win7 at least, right? I am thinking to buy a 64 bit win7 or a 32 bit win7.
Hmm, I couldn’t find a colleague with a win7 32 bits installation, so I’m not able to test it. This could be a good hint at what to go for when buying a new PC. The opportunity to use more memory is very welcome.
Got it, thanks !
Hope next Jdeveloper release will be able to use 64 bit JVM.
