Question

I’m using Rational Clearcase SCM adapter in RSA/RAD 8, and is using snapshot view.

I have just found out that a full rebuild of our code takes
15 seconds when the clearcase plugin is “disconnected.”, but
when connected it takes more than 90 seconds – on a good day…

Since the CPU, disk, and also the network is more or less
idle while compiling, I used wireshark to trace what’s going on.

The delay seems to be caused by excessive network traffic, a
few packages going forth and back to the clear case server for
each file touched in the snapshot view. Note; it’s not a dynamic view.

Is there a way to stop clearcase or the plugin from accessing the server?
It can’t be important, it works perfectly fine in “disconnected” mode.

Answer 1

I deactivated the Clear Case SCM adapter, and installed the Clear Case Remote Client instead.

The time to do a “rebuild all” time was reduced from 100s to 20s.
