UDS-D creates a distribution table based on the contents of the input file (see figure 24).
The following entries are differentiated in the distribution table:
NODE/CONF entry
contains a processor name and the first seven characters of a configuration name, possibly padded with zeros and the eighth character “@”DB entry
contains a database nameSS entry
contains the first six characters of a subschema name
The SS entry is linked to the associated DB entry, and the DB entry is linked to the associated NODE/CONF entry.
Figure 24: Structure of the distribution table created from an input file
The arrows in the distribution table point from the SS entry to the associated DB entry and from the DB entry to the associated NODE/CONF entry. This chain linking the SS entry to the DB entry and the NODE/CONF entry must be complete in order to enable the distribution component in the user task to send a DML statement to the desired subschema of a remote configuration. Otherwise, the application program will receive status code 141: “Invalid subschema definition”.
