[IDMS-L] Using DFDSS to backup to DASD

  • 1.  [IDMS-L] Using DFDSS to backup to DASD

    Posted 07-04-2007 09:55 AM
    Hi,



    We use DFDSS to backup our database files to tape. We are thinking of
    also backing up to disk as well for our DRP. What would the DCB
    information be for a disk backup using DFDSS?



    Thanks

    "I specify space only in the JCL and leave the DCB info to DFDSS.

    //DUMP EXEC PGM=ADRDSSU
    //*
    //SAVE DD DSN=CHRIS.DFDSS.DUMP.DISK,
    // DISP=(NEW,CATLG,DELETE),
    // SPACE=(CYL,(1,1),RLSE)
    //SYSPRINT DD SYSOUT=*
    //SYSIN DD *
    DUMP DATASET(INC(CHRIS.ASMLIST,CHRIS.LNKLIST)) -
    ODD(SAVE) -
    COMPRESS -
    SHR
    /*

    After execution the DCB of the output dataset on a 3390M3 shows as:

    DATA SET NAME VOLSER ALLOC USED EXT ORG RECFM BLKSIZE LRECL
    CHRIS.DFDSS.DUMP.DISK TSO005 15 2 1 PS U 27998 0

    Re: Seven Ages of an IDMS Application
    "An interesting issue. I helped put together a British Telecom IDMS
    product in the 1980s (which may or may not be one of the
    ""un-decommissionable"" ones). And when we handed its maintenance over to
    external contractors in 1988 the thing which struck me most is that the
    data modeling needs to include the humans in the loop (operators,
    designers, users, etc) as one of the most important entity types at the
    Schema design stage. The Data Dictionary needs to be talking to future
    generations of maintenance staff, every bit as much as specifying set
    structures and storage arguments. My advice, therefore, is to get a load
    of Superchief records added in with your next Service Pack release, so
    that the mapping of the Schema core to the real world is that much more
    transparent. Otherwise designers are such myopic creatures!
