Problem summary
**************************************************************** * USERS AFFECTED: All DB2 10 for z/Os REORG utility users * **************************************************************** * PROBLEM DESCRIPTION: Introduction of a new zParm to control * * the default behavior of REORG * * TABLESPACE LIST partition processing. * **************************************************************** * RECOMMENDATION: Apply corrective PTF when available. * **************************************************************** Currently by default behavior, REORG TABLESPACE LIST on a partitioned table space will result in a single REORG execution including all the adjacently specified partitions in the LISTDEF statement. For example: LISTDEF L INCLUDE TABLESPACE DBB.TSS PARTLEVEL 3 INCLUDE TABLESPACE DBB.TSS PARTLEVEL 4 INCLUDE TABLESPACE DBB.TSS PARTLEVEL 8 REORG TABLESPACE LIST L The above will result in a single REORG execution reorganizing data partitions 3, 4 and 8 in the same utility operation, as if REORG TABLESPACE PART (3,4,8) is specified. While a new PARALLEL keyword is introduced via APAR PM25525 / PTF UK64588 to override this default behavior in a case by case basis, many users find this option limiting as they prefer the behavior of reorganizing LISTDEF partitions one at a time serially (e.g. due to DASD resource constraint) and they cannot modify a large number of utility jobs to specify the overriding PARALLEL keyword. As a result, this APAR introduces a new DB2 subsystem parameter ( zParm ) named REORG_LIST_PROCESSING. This allows the user to specify the default setting of the PARALLEL option when deciding whether REORG would process the LISTDEF partitions in parallel or serially.
Problem conclusion
Code has been modified to implement the aforementioned system zParm for REORG TABLESPACE LIST processing.
