Exclusive lock for non mergable files

Is there a way to lock a file exclusively?

I know, that there is lock function available.
But when I lock a file (on a stream) others can still edit and check in this file. Solely delivering this file to the stream where it was locked is disabled.

For files where we would completely disable merges, this the "latest" possibility. Other users might waste a lot of time with changes, that they can never deliver.

This is work item 89703. This "Pessimistic Locking" feature was delivered in RTC 5.0.2.

Cheers,

Are there any work arounds known? Any hint is welcome...

I have heard about a SVN plugin TAM TAM.
With SVN it should be possible, to load all files as read only files on your local machine. When "Checking Out" a file, the TAM TAM plugin checks, if the file is locked. If locked, no Check Out. If not locked, the file attributes are changed to write.

Would it be possible, to create a similar work around for RTC? Are the extension points available, to handle this?

(In my case, we want to avoid Rhapsody model merges.)

What you describe is effectively what would be done to implement work
item 89703. So this isn't a workaround, but rather is the
implementation of that request(:-).

Geoff
