Troubleshooting Memory Issues

If you work with large schema documents, you may sometimes encounter an out-of-memory error during auto-mapping, or during test and report generation. If you receive an out-of-memory error when using the XSLT Map Editor, you must increase the heap size of the JVM to resolve the problem.

To increase the JVM heap size:

  1. Locate the config file for your application installation.

    Locate the shared Oracle JDeveloper product.conf file or the optional tool-specific .conf file located in the user's home directory. The location of these files depends on the host platform.

    • For Windows Platforms:

      The location of user/product files is often configured during installation, but may be found here:

      %APPDATA%\JDeveloper\product-version\product.conf

      %APPDATA%\JDeveloper\product-version\jdev.conf

    • For UNIX Platforms:

      $HOME/.jdeveloper/product-version/product.conf

      $HOME/.jdeveloper/product-version/jdev.conf

  2. Edit the file to change the AddVMOption to the desired value. For example:
    AddVMOption -Xmx1024M

    Note:

    The AddVMOption value can be large for 64-bit machines. Setting it close to the amount of RAM provided by the machine provides better performance.
