During the Build phase, indexes are created based on the index keys
collected in the Load phase. The index keys are sorted during the Load
phase and index statistics are collected. The statistics collected
are similar to those collected during RUNSTATS. If a failure occurs,
the Build phase restarts from the beginning.
Unique key violations are placed into the exception table, if one was
specified, and messages on rejected rows are put into the message file.
Following the completion of the LOAD process: review these messages,
correct any problems, and insert the corrected rows into the table.
Note:The recording of warnings has a detrimental effect on the
performance of the LOAD. If performance is important, and you anticipate
a large number of warnings, you should consider using the NOROWWARNINGS
filetype modifier. If this filetype modifier was specified, these
warnings are suppressed.
