Define an SMS-Managed Key-Sequenced Cluster: Example 1
In this example, an SMS-managed key-sequenced cluster is defined.
The DEFINE CLUSTER command builds a catalog entry and allocates space
to define the key-sequenced cluster SMS04.KSDS01.
//DEFINE JOB ...
//STEP1 EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=A
//SYSIN DD *
DEFINE CLUSTER -
(NAME (SMS04.KSDS01) -
STORAGECLASS (FINCE02) -
MANAGEMENTCLASS (MC1985) -
DATACLASS (VSAMDB05))
/*
The parameters for this command are:
- STORAGECLASS specifies an installation-defined name of a storage class, FINCE02, to be assigned to this cluster.
- MANAGEMENTCLASS specifies an installation-defined name of a management class, MC1985, to be assigned to this cluster. Attributes of MANAGEMENTCLASS control the data set's retention, backup, migration, etc.
- DATACLASS specifies an installation-defined name of a data class, VSAMDB05, to be assigned to this cluster. Record size, key length and offset, space allocation, etc., are derived from the data class and need not be specified.
