Syntax for an SMS Data Set

ADDDS CYLINDER=cyls BLKSIZE=b DATACLAS=dc MGMTCLAS=mc STORCLAS=sc ABOVE

where:

ABOVE

Indicates that the data set being added to the database can be allocated above the 64K cylinder line on a 3390-A device. Data sets that are allocated above the 64K cylinder line are allocated in increments of 21 cylinders, so the final data set allocation is rounded up to the next multiple of 21 cylinders.

This parameter is optional.

unit

Specifies the unit name to be used to dynamically allocate a new data set for the database.

This operand is optional.

volser

Specifies the volume serial number on which to allocate the new data set for the database.

This operand is optional.

cyls

Specifies the number of contiguous cylinders to allocate to the data set for the database, between 1 and 4369.

This operand is required.

b

Specifies the block size of the data set for the database, between 3768 and 16383 bytes.

This operand is optional and if you leave this operand blank, the default (3768 bytes) is used. This operand is valid only for the first extent of the database.

Note: When converting databases, if you specify a value for this operand that is smaller than was originally specified for the "from" database, specify a value for the delete history operand in the COPY or LOAD control statement.

dc

Specifies the SMS data class you want to assign to the data set for the database.

This operand is optional and works only if you have IBM's SMS.

mc

Specifies the SMS management class you want to assign to the data set for the database.

This operand is optional and works only if you have IBM's SMS.

sc

Specifies the SMS storage class you want to assign to the data set for the database.

This operand is optional and works only if you have IBM's SMS.
