Start up parameters

To improve the performance of WebSphere Studio, you should set several start up parameters in the initialization file. The parameters are the same regardless of the WebSphere Studio product that you use. The initialization file is always in the WebSphere Studio installation directory, but the name of the file varies with the product that you are using. For example, if you are using WebSphere Studio Application Developer, the initialization file is named wsappdev.ini. To set the start up parameters, do the following:

  1. Using a text editor, edit the initialization file.
  2. Look for the following line:
    VMArgs=-Xj9
    
  3. Change the line to the following:
    VMArgs=-Xj9 -Xmx1024m -Xms256m
    

    Setting these additional values increases the available virtual memory and stack space.

  4. Save the initialization file.
  5. Start WebSphere Studio.
