Henrik, you have a legacy system that's been proven in production for many years, and you don't want to change it. I can see that. What I can't see is people encouraging users to ignore IBM supplied tools and to reinvent the wheel on their own.
Db2 will give you a row token on read (no table changes required). If the token matches when you do your update, you're guaranteed that the row hasn't changed in the interim.

If you really want to know it, it's and old habbit that goes back to 1977 - and if it isn't broken, works well and suits the purpose - why try to fix it?
And even in 2017, where timestaming isn't enough any more (no ns support) - it still works ;-)
