I'm sorting a file with approx 3,000,000 records. The LRECL is 1400 and the file is FB. Here's my sort card:
OPTION FILSZ=E3000000,AVGRLEN=1400,DYNALLOC=(3390,2)
SORT FIELDS=(2,16,CH,A,949,6,PD,A,1,1,CH,D,18,12,CH,A)
END
How do I optimally set the number of temp work spaces in the DYNALLOC parm? I don't want to use too many because I'm going to have 15 of these jobs running in parallel. These 15 sorted files will then be merged together into one file in a common successor job. This is to replace the prior process where the 15 individual files were all sorted together in a single step that on a good day took 150 minutes. The new merge takes about 35 minutes and the 15 sorts in parallel about 6 minutes each, so this'll shave about two hours off the process (saving clock time is the concern here).
I imagine the answer to my question is in the sysout of the dfsort but I don't know how to read it. I've appended it below. Any help is appreciated.
