The section “Altering the DB configuration during the session” can be found on "Defining and altering the DB configuration".
The following must be noted for UDS-D:
If you have modified any DB configurations, you may have to adapt the distribution tables accordingly.
If there are secondary subtransactions in the PTC state, the databases involved cannot be detached from the DB configuration in a consistent state (see section “Effects of the PTC state”).
You should therefore avoid exclusions after a session abort or perform a warm start on the inconsistent databases as soon as possible to ensure proper communication between the DB configurations.
In the case of an emergency, the PTC state can also be terminated “manually” (see section “Terminating the PTC state”).
