64bit JVM and idea.exe

Hello Pete,

Is there a timeframe of when the launcher will support a 64bit JVM.
Right now I am using the idea.bat but it would be nice to use the
launcher instead.

We don't see any benefit in running IDEA under a 64-bit JVM, and because
of that we don't currently have any plans to support it in the launcher.

I have just started using the 64-Bit JVM here as the only way to get IntelliJ running with a big heap - We have a large codebase and see frequent memory issues with IntelliJ normally. With compressed oops switched on, we can have a large heap with pretty much no extra cost. This is potentially a big win for us, and it would be great if it was supported by the launcher.

There is a idea64.exe in  http://jetbrains.net/devnet/docs/DOC-1185, you can download it

First install jdk 64, then create an env variable IDEA_JDK to 64 bit jdk directory

If you use idea64.exe to start IDEA, please create  idea64.vm.properties  to config the JVM

Thanks. I gave it a go, but it just locks when I try to run it. Annoying.

I tried using the properties file you mentioned, and also tried renaming it to idea64.exe.vmoptions but neither seemed to help. I'm using 9.0.1 so maybe it's a compatibility thing.

Seriously?  You don't see any benefit to having a launcher that supports a 64-bit JDK?

I have several projects IDEA can't load into a 1GB heap, which is all I can usually manage to use when using the launcher (1280M if I'm lucky).  I'm fine running IDEA myself from a batch file, but having to set this up manually on the machines of the junior developers is a real pain.

Are you kidding?  Of course there's a benefit in it.  IDEA is a memory hog for larger projects and it works much better if you can give it more heap (which you can't do with a 32-bit JVM).  IDEA runs very well on my linux box using a 64-bit JVM.  I'd like to have the same warm fuzzy experience on my Windoze box.  Having to use the .bat file is a pain.  This should just work out-of-the-box.  It's becoming a 64-bit world, folks.

I am running idea on x64 JVM all the time because normally I have 3 to 8 projects open.

I didn't use Idea installer to get it working; instead I downloaded the distro ZIP, unzipped it wherever and tweaked the idea.bat.

In the beginning, right after @echo off, I inserted:

set JAVA_HOME=C:\jdk6x64
set JDK_HOME=%JAVA_HOME%
set IDEA_JDK=%JAVA_HOME%
then, further below, tweaked it like this:

SET IDEA_HOME=C:\bin\idea
SET JAVA_EXE=%IDEA_JDK%\bin\javaw.exe

Yeah, I got the bat to work too.  The point is that we shouldn't have to do this.  If we're paying for a product when Eclipse is out there for free, it should be able to do stuff like this.

Yeah, let's pull an Eclipse card and wave it high, wave it vigorously. Alternatively, you could use Netbeans scare, it works well on Halloween: Boo! :^O

Seriously, compared to how much I have to do to keep other stuff comfy and working the way I want, regardless if it's something as commercial as MS Office plus Visio or as "free" as Linux, it's nothing: 5 lines in a bat changed, submitted to my personal VCS for the record, done. Enjoy. Does not diminish the Idea's value in any way.
