## To rebase the Application Server’s DLLs

##### Before You Begin

To perform rebasing, you need:

- Windows 2000

- Visual Studio and the Microsoft Framework SDK rebase utility

1. Make install_dir\ `bin` the default directory.

       cd install_dir\bin

2. Enter this command:

       rebase -b 0x6000000 *.dll

3. Use the `dependencywalker` utility to make sure the DLLs were rebased correctly.

   For more information, see the Dependency Walker website.

4. Increase the size for the Java heap, and set the JVM Option accordingly on the JVM Settings page in the Admin Console.

5. Restart the Application Server.

##### Example 4–2 Heap Configuration on Windows

This is an example heap configuration used by Sun ONE Application server for heavy server-centric applications, on Windows, as set in the `server.xml` file.

    <jvm-options> -Xms1400m </jvm-options>
    <jvm-options> -Xmx1400m </jvm-options>
