We are cluelessly converting a few C# applications to use Oracle instead of SQL Server. I barely understand ADO.net, but it appears that it uses optimistic concurrency. Which means the record to be updated could be updated by another user without the original user realizing it. The current thinking is to rewrite the app back to C and host it on a UNIX box. While I am not a big fan of Windows, I just believe the rewrite to be a drastic move. So I am trying to figure what we can do.... - I haven't used Oracle Data Provider for .NET but it "appears" to be what we need. Does that sound right to anyone??? - We are using Oracle 10.2, so I wondering if we should do some slight SQL mods and use ORA_ROWSCN. Has anyone used this feature???
