Increasing the JVM heap size to import UML models from Rational Rose RealTime to Rational Software Architect RealTime Edition

If you receive an out-of-memory error when you import a Rational Rose® RealTime model into Rational® Software Architect RealTime Edition, you can increase the Java™ virtual machine (JVM) heap size to the maximum amount.

Before you begin

Before you increase the JVM heap size, reduce the memory that other parts of Rational Software Architect RealTime Edition use by closing all editors and unnecessary projects.

About this task

Note: The following steps assume that your computer has at least 2 GB of memory. If your computer has less than 2 GB of memory, modify the -Xmx argument accordingly.
To increase the JVM heap size:

Procedure

  1. Save any open models and close Rational Software Architect RealTime Edition.
  2. In a text editor, open the eclipse.ini file that resides in the following default location: X:\Program Files\IBM\SDP\. In this example, X represents the drive on which Rational Software Delivery Platform is installed.
  3. Increase the heap size by using the -Xmx argument.
    Tip: Start by increasing the heap size to -Xmx1024; then, if needed, go up in 256k increments to a maximum of -Xmx1536.
  4. Save and close the eclipse.ini file. You can now start Rational Software Architect RealTime Edition and try to import the Rational Rose RealTime model again.
