Limited Windchill 10 Access via Creo Parametric 1.0 M020

Question

Hello all FIRST folks!Hope everyone has been have a challenging yet productive season. I must admitted the we the 167 Buchanan Bird Brains have have many obstacle to overcome, yet we are still having fun and learning lots! You can read more here: Evan G's Blogtime Array.In any case, our team has been having difficulties establishing a solid connection to the Windchill 10 FIRST Robotics server via Creo Parametric. Logging into the the server via Internet browser works perfectly, but when working through Creo, strange things begin to happen. Sometimes we can connect easily and things work beautifully. Other times we can connect, then an error message saying that the server is unavailable pops up and ruins our work session. In one extreme, a student won't beabel to connect at all! I have found that usually the best temporarily solution is to delete the .wf server cache folder located in (for Windows 7) [Install root directory, usually C]:\Users\[Account Name]\AppData\Roaming\PTC\ProENGINEER\Wildfire or (for Windows XP) [Root directory]:\Documents and Settings\[Account Name]\Application Data\PTC\ProENGINEER\Wildfire. (If not those exactly, something similar.) This forces one to register the server again for a new session.My question is: Have other teams been having similar issues and/or what is the best way to resolve this problem?Thanks in advance for your help!Evan GiartaChief Executive Officer, 2011 - 2012Director of CAD and Design, 2010 - 2011Buchanan Bird Brains FIRST® Robotics Team 1671http://www.team1671.com/

I would like to reiterate Evan's request for feedback from other teams.

This is just to add to Evan's request for feedback from other teams.

I'm a mentor with FIRST Team 1671 as well as an administrator of PTC products with Pelco by Schneider Electric.

We are still looking at tracking down the server problem. It appears to be a bandwidth issue. Multiple students working in the same project from the same location appears to be the primary problem. While on occassion, we do see decent performance, it appears that more than one student checking/uploading CAD data at the same time is creating a bottleneck.

From my experience, it appears that Creo 1 is erroring out much more often than any previous release of Pro/E with Windchill. That being said, we saw similar problems with Creo 1 and Windchill 9.1, which was said not to work at all.

One thing that we've recently tried was dm_http_compression_level 6. Supposedly this will conserve bandwidth on upload to the server (in Germany of all places!). So far it appears to help to some extent, yet performance is still well below what I would expect.

Thanks,

Josh
