Startup procedure DD statements

If you are not using concatenated PARMLIB support, this section discusses the required DD statements for the HSMPARM statement of the DFSMShsm startup procedure. The DD statement names must appear as they are shown in the DFSMShsm starter set topic Starter set example. The high-level qualifier (HLQ) for these required DD statements does not have to be UID and the control data sets are not required to share the same high-level qualifier.

Required DD Name	Description
HSMPARM DD DSN=HLQ...PARMLIB, DISP=SHR	This DD statement identifies the PARMLIB member that contains commands and directives to establish a DFSMShsm operating environment. The FREE=CLOSE parameter on the DD statement should NOT be used, as DFSMShsm will automatically deallocate the parmlib dataset.
MSYSOUT DD SYSOUT=A	This DD statement identifies a system data set that provides DFSMShsm with the messages issued by the terminal monitor program (TMP) and with messages issued when dynamic memory allocation takes place.
MSYSIN DD DUMMY	This DD statement identifies a system data set that provides DFSMShsm with a DUMMY SYSIN data set for DFSMShsm support of TSO processing.
SYSPRINT DD SYSOUT=A, FREE=CLOSE	This DD statement identifies the output destination for SYSPRINT requests.
SYSUDUMP DD SYSOUT=A	This DD statement identifies the SYSOUT class for SYSUDUMPs.
MIGCAT DD DSN=HLQ...MCDS, DISP=SHR	This DD statement identifies the migration control data set to DFSMShsm.
BAKCAT DD DSN=HLQ...BCDS, DISP=SHR	This DD statement identifies the backup control data set to DFSMShsm.
OFFCAT DD DSN=HLQ...OCDS, DISP=SHR	This DD statement identifies the offline control data set to DFSMShsm.
JOURNAL DD DSN=HLQ...JRNL, DISP=SHR	This DD statement identifies the journal data set to DFSMShsm.
ARCLOGX DD DSN=HLQ...HSMLOGX1, DISP=OLD	This DD statement identifies the LOGX (DFSMShsm log) data set to DFSMShsm. If you specify LOGSW=YES, specify DISP=OLD.
ARCLOGY DD DSN=HLQ...HSMLOGY1, DISP=OLD	This DD statement identifies the LOGY (DFSMShsm log) data set to DFSMShsm. If you specify LOGSW=YES, specify DISP=OLD.
ARCPDOX DD DSN=HLQ...HSMPDOX, DISP=OLD	This DD statement identifies the PDOX (PDA trace) data set to DFSMShsm.
ARCPDOY DD DSN=HLQ...HSMPDOY, DISP=OLD	This DD statement identifies the PDOY (PDA trace) data set to DFSMShsm.
