Is it possible to read a USS file using CARLa, and accross z/Secure network

  • 1.  Is it possible to read a USS file using CARLa, and accross z/Secure network

    Posted Wed June 12, 2024 11:00 AM

    I know that you can define a file layout and CARLa can read a z/OS flat file.  My question is can it read a USS file?   And can it read it accross the z/Secure network?

    If possible, I'd very much appreciate an example of how to do it?

    Thank you,

    Hi Brent,

    A CARLa sample for reading a USS file is the following:

    deftype type=uss#
    alloc type=uss# path='/home/user/text87.txt'
    newlist type=uss#
    sortlist recno record

    I modified the 'alloc' statement to

    alloc type=uss# path='/home/user/text84.txt' zsecnode=s84node

    to read a USS file on a remote system but found that this is currently not supported.
    The 'alloc ... zsecnode' documentation only hints at this by saying that
    reading remote "system data or data sets" is possible, not mentioning "USS files".

    Regards,
