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.
Syntax
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.
