Whether you encounter an out-of-memory error depends on many
factors, including, but not limited to, the size of your XDE model and how
much RAM your machine contains. If your XDE model is collectively greater
than 200 MB (including all referenced models and subunits), there is a higher
risk of encountering an out-of-memory error during the import process even
if your machine has a 2 GHz processor and a sufficient amount of memory.
There
are two levels of error severity related to memory consumption that may occur
during the XDE import process. When the Rational
® XDE Model Import wizard detects
that available memory is running low, the wizard automatically stops migrating
diagrams, even though the model continues to migrate model elements. When
this situation happens, an incident is logged in the XDE import report. The
more severe error occurs when all memory available to the process is completely
exhausted. In this case, the import process stops and an internal error window
opens, explaining that an out-of-memory error has occurred.
Important: Before
you attempt any of the steps below, you should temporarily reduce the memory
used by other parts of the Rational UML modeling products by closing all editors
and unnecessary projects. Then, restart the Rational modeling product and try to
import your XDE model.
