I have run into an issue with JDeveloper when I am trying to build a composite to deploy for Sugar. I am running JDeveloper 11.1.1.7.0 running on Window 7 with 16GB of RAM and when I try to build the composite I see the following message 

Buildfile: C:\Oracle\Middleware\jdeveloper\bin\ant-sca-compile.xml

scac:
     [scac] Validating composite "C:\JDevProjects\NotificationService\NotificationServiceProject\composite.xml"
     [scac] Error occurred during initialization of VM
     [scac] Could not reserve enough space for object heap

BUILD FAILED
C:\Oracle\Middleware\jdeveloper\bin\ant-sca-compile.xml:278: Java returned: 1 Check log file : C:\JDevProjects\NotificationService\NotificationServiceProject\SCA-INF\classes\scac.log for errors

Total time: 1 second

Searching around I have gotten numerous recommendations of changes to the ide.conf and jdev.conf.
JDeveloper: Could not reserve enough space for object heap

Currently I have the jdev.conf set at 

AddVMOption -Xmx512M
AddVMOption -XX:MaxPermSize=512M

and in the ide.conf I have 

AddVMOption -Xms256M
AddVMOption -Xmx512M

I have also tried changing the ant-sca-compile.xml

and adding the environment variable EXTRA_JAVA_PROPERTIES.

Nothing has been fruitful.

I compiled this fine a few days ago and now I can't get it to work. Occasionally before I would get this and I could remedy this by closing a few other applications, now that doesn't work any more.

  • Hate to ask a dumb question, but did you try restarting your computer? How much RAM does the Activity Monitor app show is available? – Matt Ball Feb 06 '15 at 21:44
  • 32 or 64 bit JVM? 32 bit JVMs require contiguous address space and whether or not that is available is entirely dependent on what dlls are loaded and "where" they are loaded in memory, which then depends on what applications are running. Before you answer, make sure you check both the JVM running jdeveloper *and* what jvm is being used by whatever spawned process is triggering the error (I imagine they can be different) – Ryan Feb 06 '15 at 21:56
  • @MattBall I did try restarting my computer numerous times. According to the activity monitor I have 10GB Available. – Zirous Tom Feb 09 '15 at 13:56

I made the following changes

Edit the ant-sca-compile.xml to have the following values :

<jvmarg value="-Xms512m"/>
<jvmarg value="-Xmx512m"/>

The jdev.conf file config should be as follows:

AddVMOption –Xmx1280M
AddVMOption -XX:MaxPermSize=256M
AddVMOption -XX:MaxHeapSize=512M

And the composite now builds.

Thanks,

Tom
