I completely refused to use dynamic views for several reasons - #1 being that if you lost your network connection you couldn't work at all, and #2 being how slow they were. Static views were slightly better as you could at least hijack files in that situation and keep working (and then be very very careful when you were back online). And then of course there was ClearCase Remote Client. I was working from home much of the time, so I got to use CCRC. It worked kinda well enough, and in that situation was much better than the native client. Don't ever ever try to use ClearCase native over a non-LAN connection. I can't stress this enough. The ClearCase protocol is unbelievably noisy, even if using static views. CCRC did have one major advantage over the native client though. I had the fun task when I moved my local team from CC to Mercurial of keeping the Mercurial and CC clients in sync. Turns out that CCRC was the best option, as I was able to parse its local state files and work out what timestamp ClearCase thought its files should be, set it appropriately from a Mercurial extension and convince CCRC that really, only these files have changed, not the thousand or so that just had their timestamp changed ... CCRC at least made that possible, even if it was a complete accident by the CCRC developers. Tim Delaney
