APAR status

  • Closed as program error.

Error description

  • On Windows, ffstsummary.exe fails to read FDC files more than 2
    GB in size.
    
    This output is written to the screen:
    
    ffstsummary fails with this in the output, when a file is bigger
    than 2 GB:
    ffstsummary: ERROR: Failed to stat file AMQ12345.0.FDC (errno
    132: value too large)
    

Local fix

  • Split the large FDC file into smaller chunks and re-run
    ffstsummary
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users who run the ffstsummary program to provide an ordered
    history of FDC files.  Note this problem only affects you on
    Windows, and only if one or more of the FDC files are huge
    (greater than approximately 2 GB).
    
    
    Platforms affected:
    Windows
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    The code within ffstsummary.exe was using a 32-bit version of
    the operating system call 'stat' to discover the size of the FDC
    file.  It should have been using the 64-bit version of the call.
    

Problem conclusion

  • The MQ code within ffstsummary.exe has been corrected, to use
    the 64-bit version of the operating system call made to discover
    the size of the FDC file.
