CLIENT32 v2.5 DOS WINDOW FILE LOCKING
Posted on 1998-10-21
Netware 3.12 server, WIN 95 and DOS 6.22 workstations all running an Acucobol DOS Accounting application. WIN 95 stations DOS window freezes randomly but 6.22 stations run well. In tracing the problem I stumbled on NTEST386 that is a Clipper test module that can be set up to share a file from all stations. Diagnostics showed that file locking parameters go into orbit on the Win 95 stations. This might be a clue because at other sites with fewer clients and smaller files the errors do not occur. Locking was an issue before but Acucobol delivered a runtime update.
The network seems stable over the last couple of years with no file damage or abends at all. We have both a 10 Mb segment and 100 Mb segment and note that there are fewer freeeze ups under Win 95 on 100 Mb. NTEST386 running on only one win 95 station runs into file locks - presumably its own. I have contacted the author but he is 'on the road' until next week.
We could switch to Btrieve to get away from client locking but want to try other options first.
Any and all help will be appreciated.
