I have created a tape sequential data set (i.e. UNIT=TAPE).I tried to edit/view using start 3.4 option in TSO and i was not able to open it at all.Please let me know how can i view/edit a tape data set.

Thanks,

You can't unless your TSO ID has been granted tape mount authority (which is highly unlikely).

Ok thanks. Does it mean there is no way to access tape data set unless i have mounting authority?


Thanks,

You can dump it back to disk and browse there.

Hello,

Tape is meant to be used in batch processes, not online editing. . .

Most organizations will not allow developers to access tape datasets in their tso/ispf sessions.

If you do dump data to dasd to use intso, suggest you only dump a few records so that the volume will be managable.

Thanks. I am not sure how to dump back to dasd.Could you please let me know how can i dump data to dasd?

Rather depends on how the tape was created really.

Hello,

What is the recfm for the file? If you post the jcl that created the file, that may help. . .

Your sort product may be the tool you want to use - as Expat mentinoed, this depends on how the tape was created.

The following is the statement used to create a tape data set.

//GL1BIGW DD DSN=THHH.OSU.NAVEEN.OUTPUT,
// DISP=(NEW,CATLG,DELETE),UNIT=TAPE,
// DCB=(RECFM=FB,LRECL=1200),
// SPACE=(TRK,(2,3),RLSE)

Hello,

How much data is on the tape? What pgm= was used to create the tape?

You can use your sort product to copy some of the data to dasd. If there is a high volume of data on the tape, you may not be able to copy all of it to dasd. With the sort product, you can select some of the data rather than copying all of it.
