The following prerequisites should be satisfied by OpenTP1 nodes containing UAPs which execute the facilities for cluster system or parallel processing system:

• TP1/Multi must be installed.
• Y must be assigned to multi_node_option in the system common definition.

However, none of the above prerequisites must be satisfied when:

• The user server status acquisition function (the function dc_adm_get_sv_status()) is used to acquire the status of the user server at the own node.
• The node identifier of the own OpenTP1 node acquisition function (the function dc_adm_get_node_id()) is used.

The figure below shows the outline of the application programs in cluster/parallel mode.
