Using MVS Hardware Configuration Definition (HCD)
The MVS™ hardware configuration definition (HCD) provides
an interactive, panel-driven dialog that you can use to define hardware
configurations. HCD also provides an option that creates JES3 initialization
stream data for use in step 2 of the initialization stream checker
utility. Perform the following steps to obtain the JES3 configuration
data using HCD:
- Select the "Activate Configuration Data" option on the HCD primary panel. HCD next displays the JES3 panel.
- Select the "Create JES3 Initialization Stream Data" option from the JES3 panel.
- Specify the following items on the JES3 panel:
- Data set name (This name will be used later in the STG1CODE DD when running IATUTIS.)
- Eight character MVS configuration identifier
- Eligible device table (EDT) identifier
You can also create the initialization stream data using
a batch job like the following:
//jobname JOB 'ACCTINFO','NAME',MSGLEVEL=(1,1),
// MSGCLASS=R
//BUILD EXEC PGM=CBDMGHCP,PARM='CONFIG,JES,cccccccc,ee'
//HCDIODFS DD DSN=SYS0.IODFxx,DISP=SHR
//HCDDECK DD DSN=dsname(member),DISP=OLD
where: - xx is the suffix of the I/O definition file to be used as the basis for this data.
- cccccccc is the eight character MVS configuration identifier.
- ee is the eligible device table (EDT) identifier.
- dsname is the data set name to contain the output data (and to be used later in the STG1CODE DD when running IATUTIS).
- member is the member of the output data set to contain the data for a particular processor.
MVS places the configuration data in the data set you specify. IBM® recommends that you place the data into a partitioned data set (PDS) because the initialization stream checker requires, as input, a PDS whose member name(s) match the names of the mains that you specify in the JES3 initialization stream.
