Multiple Source Parallel Maintenance
This highly parallel load scenario with write operations uses only two simple exits: one
to build the key from a raw record (the BUILDKEY exit in the initial DataLoader/MP
process) and one to convert a raw record to a suitable format (the CONVERT exit in
downstream DataLoader/MP processes).
Figure 6-4 shows multiple input streams. Assume that you are inserting or updating the
database as appropriate.
Note that Figure 6-4 is exactly like Figure 6-2 except that there is more than one input
stream, and you must have one initial DataLoader/MP process for each stream. You
could use DataLoader/MP’s statistics report to adjust the number of downstream
DataLoader/MP processes and modify the input stream to start them.
