We have been having problems with using SCC mode to control PVCS from Rhapsody (we set up Rhapsody with UseSCCtool = yes, and activate PVCS Trackerlink, so it responds to SCC commands).

Since installation of Rhapsody version 7 (up to and including MR3), on attempting a check-out we have had errors "Initialize failed" and Rhapsody sometimes crashes. A recent trial has confirmed that the problem did not exist in version 6.2.

Problem was raised with Telelogic back in February, but they don't seem to have found the cause yet --- has anyone else had this problem and could you provide further evidence that might help them solve it?
If you want to make a separate call to Telelogic, you may wish to cross-reference to our call ref 84586.

The cause of the problem reported by Charlie has now been identified - and it is a problem with PVCS that appears to be limited to PVCS SCC implementation which is why both Rhapsody and PVCS can run simultaneously, albeit independently.

The Rhapsody Rules Composer needs the JVM.DLL in order to run, and when Rhapsody is launched, that file is loaded into memory. The PVCS SCC implementation also needs the JVM.DLL, but PVCS appears to load the DLL without checking to see if it is already in memory, and this results in the crash.

We have notified PVCS support about this problem, but in the mean time there is a workaround - remove the [RulesComposer_Generator7.0] section from the rhapsody.ini file, as well as the reference to RulesComposer_Generator7.0 in the [Plugin] section. This will stop Rhapsody from loading the Rules Composer when Rhapsody is launched, which in turn will stop the JVM.DLL file from being loaded. Rhapsody / PVCS integration via the SCC interface will now work normally.

Hi all, Just to give you an update on this.

The things in Rhapsody that seem to cause problems with PVCS are those that involve Java. Currently the things we are having to do without are the RulesComposer plugin and also the Welcome Screen (actually, this is why some of our users started experiencing the problem when Rhapsody 7 was released). With both of these disabled, our PVCS integration is running acceptably.
