Attempts to synchronize an IBM Rational ClearCase (CC) UCM Stream with IBM Rational Team Concert (RTC) using the RTC Eclipse UI results in the following error: "Synchronization blocked by error: Synchronized stream is currently in use by another stream"
Two symptoms will occur:
- The following error message is displayed:
Synchronization blocked by error: Synchronized stream is currently in use by another stream
- The synchronization fails.
The ClearCase stream is locked due to a failed synchronization in the past.
RTC / CC Connector integration.
Resolving the problem
To resolve this error, we need to unlock the stream.
NOTE: It is typically NOT advisable to select Unlock during active synchronization. However, when a synchronization is failing with this particular error, this action will correct the status in Rational Team Concert and ClearCase and a new synchronization can start.
To Unlock the stream:
- Go to the properties of the ClearCase synchronized stream in the RTC Eclipse client.
- Click on the Unlock button.
- Attempt the synchronization again. It will succeed.
