Some level of synchronization stamps are used, even for system tables.
FILE and the adding of the TABLEDDL source member creates synchronization stamps according to the required STAMP BY settings.
If those STAMP BY settings are specified incorrectly in the DMCL, the DB001036 is possible.
Note that if the STAMP BY settings are incorrect at the time the catalog is being created, the TABLEDDL job will fail anyway.
Therefore, the only way for this problem to occur is for the catalog segment and DMCL to be changed after the catalog was originally created.
