Updating from 8.2 to 8.4

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I was hoping to finally get the servers updated from 8.2 to 8.4 over the festive season, but by now I think I've left things too tight.

Is it necessary to update the (Windows) ODBC driver as well? I've got a couple of app servers still on NT4 with ODBC 8.02.0100 which I'm trying to be careful with lest I put something on them which requires a later OS and can't back out.

The apps are written in a rather old version of Delphi with BDE which is fine with 8.2. Trying to run against 8.4 I get "Couldn't perform the edit because another user changed the record."- looking back through this and other MLs I see suggestion that this could be caused by an excessive number of decimal places in the data (current case only contains integers, timestamps and text) or possibly by a transaction isolation issue.

I'll carry on hacking at this from the app side but is there anything obvious that I've missed?
