Adabas Parallel Services allows you to use multiple images of the Adabas
             server within a single operating system image, in order to provide improved
             scalability. The cluster of Adabas servers can take part in distributed
             transaction processing, under the control of Adabas Transaction Manager. This
             is controlled by the ADARUN DTP parameter, in the same
             way as for a standard Adabas nucleus. The same value must be specified for the
             DTP parameter for every nucleus in the Parallel Services
             cluster.
