Ignoring specific XDE model items to reduce memory consumption

You can choose to ignore specific model artifacts such as profiles, type expressions, and diagrams during the XDE model import process by editing the rationalsdp.ini file. Ignoring specific artifacts cuts down on the amount of memory required to import XDE models into the Rational® modeling products.

Before you edit the rationalsdp.ini file, close the Rational modeling product you are using.

The following table lists the artifacts that can be ignored during import and the related key you use in the rationalsdp.ini file.

Ignored artifact Key Description
Type expressions
-DXDE_IMPORT_NO_TYPEEXPR
When you use this key, type expressions are not imported into the Rational modeling products. While your imported model lacks type expressions after import, this key provides the least reduction in memory.
Diagrams
-DXDE_IMPORT_NO_DIAGRAMS 
When you use this key, diagrams are not imported into the Rational modeling products. After import, manually recreate the diagrams most important to your model, as needed.
Profiles
-DXDE_IMPORT_NO_PROFILES
When you use this key, profiles and type expressions are not imported into the Rational modeling products. In some instances, type expressions migrate as stereotypes in profiles so type expression migration is suppressed when you ignore profiles during the import process.
Profiles and diagrams
-DXDE_IMPORT_NO_PROFILES_AND_DIAGRAMS
When you use this key, profiles, diagrams, and type expressions are not imported into the Rational modeling products. While this key provides the most reduction in memory usage, you lose a lot of XDE model artifacts in the generated model.
Note: If you use one of the above options to reduce memory consumption, the XDE import report only displays unexpected internal errors.

To ignore specific XDE model artifacts during import:

  1. In a text editor such as WordPad, open the rationalsdp.ini file that resides in the following default location (where x is the drive that the Rational Software Development Platform is installed to): x:\Program Files\IBM\Rational\SDP\6.0\.
  2. Add one of the keys described in the table above to the rationalsdp.ini file. For example, add the VMArgs=-DXDE_IMPORT_NO_DIAGRAMS key to import XDE models without diagrams.
  3. Save and close the rationalsdp.ini file.
Start the Rational modeling product and import your XDE model or model set again.
