The BLOCKNUM Parameter controls blocking factor for most of the workfiles used by CA IDMS/DB Reorg. You cannot specify a blocking factor for the CNTRL1, CNTRL2 and PAGUTIL files.
Rules
The block-size value must be from 1 through 32.
For work files stored on tape, use 32.
For work files stored on disk, use a number that represents half track blocking.
