JDeveloper: Could not reserve enough space for object heap
Hi i am encountering the following error when deploying an project from my jdeveloper studio.
[scac] Error occurred during initialization of VM
[scac] Could not reserve enough space for object heap
Can anyone advise on how to resolve this issue?
In case you have enough free RAM on your computer:
go to jdev.conf file ( ~/Oracle/middleware/jdeveloper/jdev/bin ) and add more memory to the file
I haven't checked but you could add:
AddVMOption -XX:MaxHeapSize=512m
or whatever you want
more help here
See in jdeveloperbinant-sca-compile.xml
Change Xmx value of line specified in JDe. Your system can't reserve enought memory.
Reducing the value -Xmx on jdeveloperbinant-sca-compile.xml worked for me:
<target name="scac" description="Compile and validate a composite">
<scac input="${scac.input}" outXml="${scac.output}" error="${scac.error}" appHome="${scac.application.home}" failonerror="true" displayLevel="${scac.displayLevel}">
<jvmarg value="-Xms128m"/>
#<jvmarg value="-Xmx1024m"/>
<jvmarg value="-Xmx700m"/>
<jvmarg value="-XX:PermSize=32m"/>
<jvmarg value="-XX:MaxPermSize=256m"/>
<!-- jvmarg value="-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005"/ -->
</scac>
</target>
If you change jdev.conf you may experience the error:
