Troubleshooting
Problem
Attempts to use Java add-ons in IBM Rational Rhapsody results in java.lang.OutOfMemoryError.
Symptom
The full error message is as follows:
java.lang.OutOfMemoryError: Java heap space
When you open a Rational Rhapsody project, you possibly see Java Virtual Machine (JVM) error -4.
An example of an add-on is arxml import/export.
Cause
The JVM needs more memory.
Resolving The Problem
Increase the JVM maximum heap size through the JVM parameter -Xmx.
To do so, you can change the Java settings in rhapsody.ini.
|
If the JVM initialization fails with JVM error -4 after you increased the maximum heap size, change other JVM parameters.
Examples
Disable Just In Time (JIT) through the following parameter.
|
You can disable JIT in rhapsody.ini.
JavaLocation=... VMArgs_MaxHeapSize=-Xmx512m VMArgs_JIT=-Djava.compiler=NONE Options=ClassPath,LibPath,VMArgs_MaxHeapSize,VMArgs_JIT ... |
Use the following Rational Rhapsody command-line parameter.
|
This parameter initializes the JVM during initialization of Rational Rhapsody, before Rational Rhapsody opens the project and uses and fragments more memory.
The command-line also need to include all other JVM related command-line options, for example.
|
Note that you need to remove the corresponding JVM related command-line options from rhapsody.ini.
For example remove the following line.
