How to increase the heap size of the integrated server in JDeveloper 12c

Sometimes there may be a need to increase the heap size of the integrate weblogic server within JDeveloper.   Obviously one can modify the setDomainEnv file in the domain's bin directory -

 

For Unix, it is in  $HOME/.jdeveloper/system12.1.3****/DefaultDomain/bin

For Windows,  it is in %APPDATA%\JDeveloper\system12.1.3***/DefaultDomain/bin

 

But, you can also change it within JDeveloper, you can do this by

 

Right click on the integratedWebLogicServer in Application Window and select properties->Launch Settings

 

JDevWLSHeapSize1

Click on More Launch Settings and create a new environment variable entry  USER_MEM_ARGS with the desired JVM heap size.

 

JDevWLSHeapSize2

 

You can also enter any Java Options in the parent dialog or use any other environment variable entry.

 

However, currently there is a caveat of doing this.  It will only be effective if you do not have any application open before you start the server.
