Changing JVM used by Studio

You may change the Java runtime environment used by Oracle BPM Studio after installation.

See Supported Operating Systems and JVMs for a list of supported Java Virtual Machines on each environment.

To change the Java runtime used by Oracle BPM Studio:

Open configuration file <ORABPM_HOME>/eclipse/eclipse.ini with a text editor.

Example contents of eclipse.ini:

-showsplash
fuego.eclipse.studio
-vmargs
-Xms128m
-Xmx512m

-Dfuego.fstudio=true
-DprodMode=preProduction
-Dbea.home=c:\OraBPMStudioHome\..
-Djava.endorsed.dirs=""
-Dsun.lang.ClassLoader.allowArraySyntax=true
-Dfuego.studio.engine.java.options=-Dsun.lang.ClassLoader.allowArraySyntax=true
-XX:PermSize=64M
-XX:MaxPermSize=128M
-Xbootclasspath/a:/bea/OraBPMStudioHome/eclipse/jre/lib/ext/tools.jar

Insert two lines at the top of the file: one containing the text -vm and one containing the full path to the java command of your Java runtime. Example, add the following two lines:
```
-vm
C:\Java\JDK\1.6\bin\javaw.exe
```

Modify existing lines referring to other Java runtime environments.

Example, change the following line:

-Xbootclasspath/a:C:\OraBPMStudioHome\eclipse\jre\lib\ext\tools.jar

to:

-Xbootclasspath/a:C:\Java\JDK\1.6\lib\ext\tools.jar

Example modified contents of eclipse.ini:

-vm
C:\Java\JDK\1.6\bin\javaw.exe
-showsplash
fuego.eclipse.studio
-vmargs
-Xms128m
-Xmx512m

-Dfuego.fstudio=true
-DprodMode=preProduction
-Dbea.home=c:\OraBPMStudioHome\..
-Djava.endorsed.dirs=""
-Dsun.lang.ClassLoader.allowArraySyntax=true
-Dfuego.studio.engine.java.options=-Dsun.lang.ClassLoader.allowArraySyntax=true
-XX:PermSize=64M
-XX:MaxPermSize=128M
-Xbootclasspath/a:C:\Java\JDK\1.6\lib\ext\tools.jar
