The most common way of getting this error is if you have not yet had a
successful sync of a stream (the sync definition gets created by the
sync request, not when the sync stream is created). Have you had a
successful synchronization of this stream yet?

First, just to make sure that nothing funny has happened to your sync
stream, request a sync on that stream.

If that sync is successfully started, and then successfully completes,
try asking for the sync history again.

If you get the same error message reported below, go to the Jazz
Provider Properties of the sync stream, and find the value of the
BUILD_ENGINE_NAME property.

Then go the the Team Artifact Navigator view, open the project that
contains the sync stream, and open the Build Engines folder.

You should find a build engine there with the name specified in the
BUILD_ENGINE_NAME property. Right click on that build engine, and
select Show Build Activity.

That should display the synchronization history.

Let me know what happens when you try this sequence of steps.

Our code does not detect what is in effect a "move" of the repository to
a new URI. I'll add a workitem for us to do so.

One simple thing to do in this case is just create a new sync stream on
that ClearCase stream.

If you want to keep using the existing sync stream, then you can just
change the appropriate argument in the synchronization.bat script
(you'll recognize it :-). Another way to get the script regenerated is
to just change the sleep time of the synch engine by modifying the
BUILD_ENGINE_SLEEP_TIME property of the Jazz Provider (this will
automatically regen the synchronization.bat script, at which time it
will pickup the new repository URI). Then execute the "restart sync
engine" operation, and verify that the sync engine can successfully be
started.

Once you have a new or fixed sync stream, request a sync, and verify
that the sync succeeds.

(If the sync fails with "sync stream in use", "unlock" the sync stream
from the ClearCase Provider Properties page, as described in a previous
message, and then re-request the sync).

And THEN you should have a sync history.

When the sync was working, the repository connection was
https://localhost:443/...... Now I changed the URL to the IP of the
jazz server. This seems contributed to the issue.

Synchronization.bat window shows the following message.....
