Dumping a data set

Do not use a data set name that DFSMSdss will reference during execution. Otherwise, enqueue contention with the operating system initiator will occur. This example shows how to back up a DASD data set to tape:

//MYJOB    JOB   accounting information,REGION=nnnnK
//STEP1    EXEC  PGM=ADRDSSU
//SYSPRINT DD    SYSOUT=A
//DASD     DD    UNIT=3380,VOL=(PRIVATE,SER=111111),DISP=OLD
//TAPE     DD    UNIT=3480,VOL=SER=TAPE01,
// LABEL=(1,SL),DISP=(NEW,CATLG),DSNAME=MYDATSET.BACKUP
//SYSIN    DD    *
 DUMP DATASET(INCLUDE(MYDATSET)) -
      INDDNAME(DASD) OUTDDNAME(TAPE)
