APAR status

  • Closed as program error.

Error description

  • Currently TPNS only has the ability to read and write to
    QSAM files via the ITPFIOX user exit. This change will allow
    users to write their own file handling routine which can
    interface with TPNS scripts.
    
    An intermittent S0C4 abend while running the log comparison
    program ITPCOMP in WSIM. The problem appears to occur when there
    are significant differences in a changed screen. The problem
    appears to occur due to an issue with the Partition Control
    Block addressing. This change for TPNS will ensure a similar
    problem does not occur in this product.

    ITPFIOX is limited to handling QSAM files and only allowing
    OPEN, READ, WRITE and CLOSE as options. This restricts what data
    the customer can read in from or pass to WSIM. It also restricts
    how WSIM can provide data for external use.
    
    The program ITP3CLPA abends due to a null address for the
    pointer to the Partition Control Block. This causes the
    addressing of areas of memory that are not accessible to the
    program. This occurred in WSIM and this change in TPNS will
    ensure a similar incident doesn't occur in this product.

Problem conclusion

  • A new User Exit program called ITPUIOX has been written. This
    program is a skeleton program that has links into WSIM
    information and storage areas. It also has places where a
    customer can add in their own file handling routines to pass
    data to or read data from an external file. While it has
    essentially the same options as ITPFIOX - OPEN, READ, WRITE,
    CLOSE - it has the potential for additional options to be coded
    or for modifying these basic four options.
    
    A test was added to make sure the pointer to the Partition
    Control block was valid and usable.
    
    Sample code to turn an unformatted CTRACE file containing the
    trace entries for TCP/IP processing into a TPNS script.
