generate REDO SQL for RI actions

Our DBAs would like to have REDO statements for any RI-action generate by DB2 (e.g Delete Cascade). At the moment ALA is assuming that the RI defined on the source system also is defined on the target system.

snip from the manual:
As previously mentioned, for REDO purposes, no records marked UPD-RI

or DEL-RI will be included in the SQL. This is because the originating action

(the original SQL which caused the referential constraint SQL) is to be

re-done, which will once again activate those referential constraints, so no

extra work is needed. For UNDO purposes, those records marked as UPD-RI and

DEL-RI will be included, but only after the originating SQL is un-done. This

is necessary because referential integrity would otherwise prohibit the

activated actions without the existence of the associated parental key


It could be nice to have an option to generate REDO sql for RI-actions, so we can apply this in a system with no definition of RI

We have been talking to Jorn Thyssen from Rocket software, who asked us to create an AHA
