Problem summary

  • ****************************************************************
    * USERS AFFECTED: Users with a tape library using the native   *
    *                 VSE Tape Library Support (SYS ATL=TLS).      *
    ****************************************************************
    * PROBLEM DESCRIPTION: A calculated buffer size exceeds 16 MB  *
    *                      causing the LBSERV request to be        *
    *                      terminated with RC8 RSN76.              *
    ****************************************************************
    * RECOMMENDATION: Apply the PTF if you use a tape library      *
    *                 with the native VSE Tape Library Support     *
    *                 (SYS ATL=TLS) and you are approaching        *
    *                 46000 volumes in the library.                *
    ****************************************************************
    $IJBAOM allocates a temporary buffer from the system GETVIS
    area to hold inventory data for each volume in the library.
    The maximum size of this buffer is constrained to 16 MB. If
    the number of volumes in the library exceeds about 466000
    volumes, the calculated buffer size exceeds 16 MB and the
    LBSERV request will be terminated with RC=0008 REASON=0076.
    

Problem conclusion

  • The PTF removes the constraint of the maximum buffer size, so
    that it is only constrained by the largest free available block
    in the system GETVIS area (see AR command GETVIS SVA).
