Zone statement

ddname

The ddname must match the name of the target or distribution zone.

Use

The zone DD statement is used by SMP/E to access an individual target or distribution zone in a CSI data set. For example, to have SMP/E access target zone MVSTGT1, you can provide a DD statement like this one:

//MVSTGT1  DD DSN=SMPE.SMPCSI.CSI,DISP=SHR

If you do not provide a DD statement for a target or distribution zone, SMP/E allocates the zone dynamically using the ZONEINDEX information in the GLOBALZONE entry. Also note that, while DD statements may be used to override the ZONEINDEX information, they are not a substitute for a zoneindex. A zoneindex is always required for a zone.

Attributes

VSAM; RECORDSIZE(24 143), KEYS(24 0).

Device

Direct access only.

Note:

The low-level qualifier of the data set name must be CSI.
If you have used IBM SMP/E for z/OS, V3R6 to update a zone, you might not be able to process that zone with previous releases of SMP/E. For more information, see the migration section in SMP/E for z/OS User's Guide.
When running on systems with the required level of DFP, SMP/E automatically takes advantage of the local shared resource (LSR) feature of VSAM. This reduces the number of times SMP/E must access data when it is reading CSI data sets. As a result, SMP/E performance is improved for commands such as APPLY, APPLY CHECK, ACCEPT, ACCEPT CHECK, and especially LIST.
CSI data sets should usually be allocated dynamically. However, you may want to use the batch local shared resources (BLSR) subsystem with expanded storage hiperspaces (instead of SMP/E's implementation of LSR) to improve SMP/E performance during APPLY and ACCEPT processing for a large number of changes. For more information about BLSR, see the notes section in SMPCSI.
