REORG needs to be enhanced to separate processing for partitions having dictionaries and no dictionaries

Using LISTDEF there are 4 partitions selected to be reorged.

Row length 2284 bytes


PART 5 - CARDF 50M, dictionary

PART 6 - CARDF 60M, dictionary

PART 11 - CARDF 110M, dictionary

PART 80 - CARDF 150,000, no dictionary

Since PART 80 does not have a dictionary and all PARTs are being reorged in the same invocation of REORG, PART 5,6,11 rows are uncompressed. This causes added MIPS and increases the DASD requirements for SORTDATA.

I am proposing REORG splits the processing into two runs. Partitions with dictionaries and Partitions without dictionaries.

Run 1 - Part 5,6,11

Run 2 - Part 80
