XSUTDYNM (sequential data set allocation) automation control point

blksize

Size of each block, in bytes

Not applicable

dataclas

SMS data class for this data set

You can change this value. You must change this value if allocation is being performed with SMS DATACLASS.

Blank (default) or SMS data class value

dsname

Data set name of the object to be allocated

Not applicable

dsntype

Data set type

• LARGE
• BASIC
• EXTPREF
• EXTREQ
• HFS
• PIPE
• PDS
• PDSE

mgmtclas

SMS management class for this data set

You can change this value. You must change this value if allocation is being performed with SMS MANAGEMENTCLASS.

Blank (default) or SMS management class value

maxvol

Maximum number of different volumes that can be used

0 through 59

If the estimated size for the work data set is greater than 1000 cylinders, the size is divided by 1000 to obtain the number of volumes. This value is added to the number of volumes specified in the+WORKUNIT parameter. If the result of this calculation is greater than 59, then the maxvol variable is set to 59.

retpd

Retention period, in days

Not applicable

primary

Primary space allocation in units, specified by the variable spaceunit

Not applicable

secondary

Secondary space allocation in units, specified by the variable spaceunit

Not applicable

The value for secondary must be greater than 0. A value of 0 will produce unpredictable results.

size

Number of 4 KB blocks that are required for this data set

You can use this value to change the values in the primary and secondary variables to apply to a different spaceunit.

Not applicable

This value is the number of 4 KB blocks required, regardless of whether the value specified for blksize is 4K.

The calculation of size does not include the number of pages to be added for the variables freepage and pctfree.

spaceunit

The allocation unit used for the primary and secondary allocation

• B (blocks)
• C (cylinders)
• T (tracks)

storclas

SMS storage class for this data set

You can change this value. You must change this value if allocation is being performed with SMS STORAGECLASS.

Blank (default) or SMS storage class value

unitname

DASD unit name for this allocation

This value must be a value that is acceptable on your system.

Not applicable

volser

List of available volumes for the data set allocation.

A string of no more than 10 volumes, exactly 6 bytes for each volume, not separated by commas or blanks

For example, to specify volumes PRD238, TST223, DEV283, DEV012, PRD231, TST162, volser would be specified as follows:

The automation control point might set this variable to a string of DASD volume serial numbers or not set a value for the variable.

0

(default value) Signifies normal completion

No action is required.

Any other value

Abnormal termination

Set the rc variable to any non-zero value to cancel the entire job.
