The REORG_INDEX_NOSYSUT1 subsystem parameter specifies whether the REORG INDEX SHRLEVEL REFERENCE or CHANGE utility should avoid using the SYSUT1 or work data set to hold the unloaded index keys. The utility passes the unloaded keys in memory as input to the index build for this process. Enablement of this option also allow REORG INDEX to utilize parallel sub-tasking to unload and to build the index keys in its internal processing.
The following values are supported:
- YES
- The REORG INDEX utility avoids using the SYSUT1 or specified work data set to hold the unloaded index keys, and also uses parallel sub-tasking to unload and to build the index keys.
- NO
- The REORG INDEX utility uses the SYSUT1 or specified work data set to hold the unloaded index keys.
