REDUCEXT parameters used with Allocation
REDUCEXT accepts the following parameters to maximize flexibility.
REDUCEXT parameters
Parameter | Usage |
|---|---|
VL | Indicates the volumes to be included for processing An asterisk (*) can be used for pattern masking. An asterisk indicates that any characters after the asterisk can be ignored. |
SG | Indicates the storage groups to be included for processing If neither VL nor SG is coded, the default is to process all volumes. |
NX | Indicates the number of extents that are used before a data set is a candidate for reorganization The default is 16 (the number of extents that z/OS allows per volume), which indicates that the data set is multivolume. If reorganization is desired based on fewer extents, you can specify a smaller number. Any number over 16 is not accepted. Numbers 1 through 9 should be prefixed with zero. Any non-VSAM data set with 16 or more extents is eligible for extent reduction, regardless of whether BMC AMI Storage was responsible for the added volume. |
WK | Indicates the name of a work volume (for non-SMS- managed data sets) This volume may also be used for SMS-managed volumes, but is not required. |
SIM | Displays the DFDSS control cards that are generated No actions are executed. This parameter can be used prior to actual execution to determine which data sets will be processed. |
NORUN | Indicates for DFDSS to be called in NORUN mode This parameter can be used prior to actual execution to determine which data sets will be processed. |
ONEWAY | Specifies that non-SMS data sets will not be copied back to the originating volume but will reside on the volume that is specified on the WK parameter |
SYS1 | Allows processing of SYS1 data sets If this parameter is not specified, SYS1 data sets are ignored (which is the default). |
