RECDEF

Reconfiguration CDS Definition (RECDEF) Control Statement

The RECDEF control statement, in combination with the CDSDEF control statement (refer to “CDS Definition (CDSDEF) Control Statement” on page 87), defines which CDS copies are to be used when running the Reconfiguration utility. CDSDEF specifies the old input copies of the CDS; RECDEF the new copies.

Note: RECDEF parameters replace the DBPRMNEW and DBSHDNEW DD statements used in previous releases. A new standby CDS created by the SLICREAT program (refer to Chapter 7, ‘‘Allocating and Initializing Control Data Sets’’ in the HSC Installation Guide) is not affected by reconfiguration. It becomes valid once it is enabled by the HSC.

Control Statement Name

RECDEF

initiates the control statement.

Parameters

DSNx

dataset.name is the name of a newly created HSC CDS. At least one DSN parameter must be specified; as many as two can be specified. The first DSN becomes the primary CDS. If specified, the next DSN is created as an identical copy of the primary CDS.

RECDEF DSNs are input for the first HSC initialization as CDSDEF control statements. DSNs can be entered in any order whether or not this is the first initialization. Order is not important, since all copies are identical after the reconfiguration and controlling information is kept in each CDS for subsequent runs.

VOLx

optionally, volser is the volume serial number of the DASD volume where the specified CDS resides. The VOL parameter must be specified in VM.

UNITx

optionally, unitname is used to specify the unit parameter in the SVC99 dynamic allocation parameter list. The UNIT parameter must be specified in VM.
