A new Rhapsody version was released by IBM last week. We have tested this version with our RXF Frameworks and we have not found a show stopping problem using it.
That means that RXF versions that are compatible with Rhapsody 8.1.5 are also compatible with Rhapsody 8.2.
For earlier than 8.1.5 versions of the RXF please read the 8.1.5 support announcement.
- In our test environment we had to start Rhapsody as administrator once otherwise the deployer threw an error message.
- Although we test as thorough as possible, there is always a minor chance that we have overlooked a change that is important to certain customers. Please test yourself before switching to a new version.
Remember to re-install the RXF for the new Rhapsody version.
Rhapsody 8.1.5 is released.
The current version of the RXF has a potential timer problem.
On systems that are running on a high load it can occur that longer timeouts are processed too late.
The timerouts are stored in a sorted list, first expiring timeout is the first list element. When a timer tick arrives only the first elements timeout value will be decreased.
On full load systems, the timeouts are not always processed immediately, so the system tick count could be larger then 1. When that happens, and the next expiring timeout has a tick value less then the system tick value, ticks would get lost.
This effect is hardly noticeable on systems with only short timeouts especially since the system is under full load anyway.
However when longer timeouts are used they will expire much later due to the stacking of this effect.. (50% longer)
The new version of the framework has corrected this error.
IBM Rational has releases Rhapsody 8.1.5, which now supports roundtripping and reverse engineering also in the 64 bit version. Also it officially added support for Windows 10. For details see IBM Rational’s release information.
Our current RXF framework releases are compatible with Rhapsody 8.1.5 with one important exception:
Earlier Rhapsody versions came with the Java run-time environment (JRE) bundled and available in “<Rhapsody program path>\jre”. Rhapsody 8.1.5 bundles a complete Java development kit (JDK), available under “<Rhapsody program path>\jdk” and containing the JRE in it’s “jre” sub-folder.
Our RXF tools like the WSTDeployer use the Java version bundled with Rhapsody and expect it to be present under “<Rhapsody program path>\jre”. To get these existing RXF releases running with Rhapsody 8.1.5, you may simply create a symlink from “<Rhapsody program path>\jre” to “<Rhapsody program path>\jdk\jre”. You need proper access rights to perform this action in a program folder.
Example how to do this on the command line with proper access rights:
mklink /d “C:\Program Files\IBM\Rational\Rhapsody\8.1.5\jre” “C:\Program Files\IBM\Rational\Rhapsody\8.1.5\jdk\jre”
You may need to adapt the Rhapsody program path to your environment.
Future RXF releases will be compatible with Rhapsody 8.1.5 natively and will be backwards compatible with earlier Rhapsody versions by automatically creating a symlink during setup.
