DFSORT (or an equivalent product) was unable to allocate the DFSORT (or equivalent product) message data set.
BLDINDEX will process the command using DFSORT (or an equivalent product) but no messages will be written to the DFSORT (or equivalent product) message data set.
For reason code 04, supply a DD statement for the DFSORT (or equivalent product) message data set (see the SORTMESSAGEDD parameter).
For reason code 08, increase the virtual storage region size and resubmit the job.
