Maybe if we could post information about environments and versions we could start narrowing down things a little? and post what is crashing, is it the terminal emulator, Natural Studio itself?
It’s a tough thing trying to narrow down what the problem is when there are so many pieces involved.
For one of the earlier patch levels of Studio we were having trouble with the terminal emulator not responding, most of the time it was the first time it was started after a PC startup. It got to the point that I could actually reproduce it on a FAIRLY regular basis and looked like it was because NDV was trying to send info back before the terminal emulation server had fully initialized (NATPccServer2.exe). After I did probably half a dozen traces on both sides the developers still couldn’t seem to find anything wrong, but in the last few patch levels of Studio the “Natural Host Server Emulation” runs as a windows service and I haven’t had the problem since, although after saying that a co-worker just had his terminal emulation session puke out, initially indicating that the session could not start. The NDV log shows some errors like:
0000006D NDV Error: PAL Error, RC:-10, ErrClass:0, Reason:1121
0BABD4B0 Sys Error, errno:1121 errno2:0x74500442 EDC8121I Connection reset.
0000006D NDV Error: PAL Error, RC:-10, ErrClass:0, Reason:0
0BABD4B0 Sys Error, errno:140 errno2:0x76697242 EDC5140I Broken pipe.
I am using the server installation option in our shop for our developers, and it looks like the “Natural Host Server Emulation” service does NOT get installed on the client. I guess my next thing to try is see if it can be installed manually (like the bufferpool service) and watch if the problems persist.
The point of all this is just to say that the more info we can provide the better the chances we can get things changed/fixed. I know it can be very difficult to get much for details, especially when it’s someone else that seems to be experiencing the problem!
Currently we are running:
Natural Studio v6.1.1 PL19 (WinXP Pro)
NDV 2.1.4 PL03 (z/OS)
Sorry for the long posting…
