CLIST ALLOCATION field

The CLIST ALLOCATION field controls the storage management properties for the prefix.NEW.SDSNTEMP and prefix.NEW.SDSNSAMP data sets, which the CLIST creates during the tailoring session.

Table 1. Acceptable values and defaults for field columns
Column	VOL/SER	DATA CLASS	MGMT CLASS	STOR CLASS
Acceptable values:	Blank or a valid z/OS® volume serial number	Blank or a valid SMS data class name	Blank or a valid SMS management class name	Blank or a valid SMS storage class name
Default:	Blank	Blank	Blank	Blank
Update:	None	None	None	None
DSNZP`xxx`:	None	None	None	None

A blank value in a column directs the CLIST to remove the corresponding storage-management-related parameters from all JCL, AMS, ALLOC, and DDL statements that are used to create data sets and storage groups that are associated with the field. A non-blank value is used by the CLIST to customize the corresponding storage-management-related parameters in all JCL, AMS, ALLOC, and DDL statements that are used to create data sets and storage groups that are associated with the field.

Recommendation: To help performance and recovery, avoid dependency on a single storage device by using an SMS scheme that uses more than one volume serial number.
