Error description

  • DTU 4.6 always allocates EQARESDS and EQATY2DS DDs if dsnames
    for them are provided, but it uses and deallocates the datasets
    only if class selection changes. Exiting DTU 4.6 without
    changing the class list leaves the DDs allocated, causing FILE
    IN USE messages on the next use of 4.6 in the same TSO session.
    

Local fix

  • Issue DDLIST and release the DS in there.
