RE: 5250 and un-do

Justin,
What do you mean by "Db2 will give you a row token on read"?
I looked for this function without success.
Thank you

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 ;-)
