Hi
Is there any way to find the Size of a file residing in a Tape?
And how to find the size of file in DASD apart from listing 'short info' in 3.4? |

How do you define the size of a tape file. What do you want to find out.
Please give some background on what you need to know, why you need to know it, and I am sure that some good suggestions will materialise.
The more information that we are given, the better the suggestion. |

Expat, here is my requirement. There is a dump job that is failing. For my research I just want to take that Dump in a DASD, previously it was tape.
Its a fullvol dump and I was here stuck with the space parameter that I have to give in my new JCL.. And I think Kevin's link will help me.
Thanks for all ur help  |

Hello,
Depending on what failure is happening, dumping to dasd may not have the same problem.
Not just everywhere would allow creating an experimental full-volume dataset 
If you post what was submitted and the error/problem encountered, someone may have a suggestion. As you have seen, going this route is causing "other things" that must be resolved before you can investigate the actual issue. |

Not sure how moving the output from tape to DASD is going to help here.
Maybe you should give details of the failing dump, such as

| If size of tape-file is your concern why not get in contact with TMS group there at your shop. And to start with what info you already have about tape in question? |

| If you know the size of the DASD volume you're dumping then you know roughly what the dump dataset size will be. If you're using something like DFSMSdss to dump it and specify COMPRESS then you might expect somewhere between 30-70% compression and accordingly reduced size dump dataset. DSS could also invoke Flashcopy which would speed the process up a bit. |

Normally nobody has to be concerned about SYSUDUMP.s or SYSABEND's.
If your system programmers are clever (and they always are), there will be enough space reserved for that kind of dumps (except if one dumb head is dumping his program every time it is started).
If we are talking about stand alone dumps then we need at least 1 tape unit, to write things to. |
