Error description

  • Customer performed a GET for an MBCS (multibyte character set)
    encoded dataset (ENCODING MBCS) with VB record format

    logical record length. An abend0c4 occured in EZAFTPMF during
    the GET processing causing the transmission of the file to fail.

Problem summary

  • ****************************************************************
    * USERS AFFECTED: All users of the IBM Communications Server   *
    *                 for z/OS Version 1 Release 13: FTP.          *
    ****************************************************************
    * PROBLEM DESCRIPTION: When an MBCS VB dataset with UTF-16     *
    *                      and a record with length equal to the   *
    *                      maximum record length is transferred    *
    *                      using GET or PUT subcommands, the       *
    *                      buffer to hold the data read is of      *
    *                      insufficient size thus overlaying the   *
    *                      buffer and causing an 0C4 abend.        *
    ****************************************************************
    * RECOMMENDATION: Apply PTF.                                   *
    ****************************************************************
    FTP incorrectly calculates the size of the read buffer
    when it reads an MBCS VB dataset with UTF-16 data. When
    the record length is greater than the size of the read
    buffer, FTP can overlay the buffer.

Problem conclusion

  • EZAFTPTO has been updated to pass the correct size of the
    read buffer to seq_read_file().
