APAR status

  • Closed as program error.

Error description

  • A job which contains a sequential file stage may intermittently
    fail, and cause a core dump, if one of that stage's input
    columns contains multi-byte characters and has a length greater
    than 128 bytes.
    

Local fix

  • Enable 'Allow per-column mapping' in the sequential file stage.
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    DataStage 7.5.3 users that have NLS enabled and import
    multi-byte sequential data.
    ****************************************************************
    PROBLEM DESCRIPTION:
    A job reading delimited data in a sequential file stage may fail
    and cause a core dump if:
    (a) NLS is enabled, and
    (b) a column's length is greater than 128 bytes, and
    (c) the input data for that column contains multi-byte
    characters.
    ****************************************************************
    RECOMMENDATION:
    Apply the patch for JR35363.
    ****************************************************************
    

Problem conclusion

  • The sequential file stage implementation was writing beyond a
    column's allocated buffer during multi-byte processing.  This
    was corrected by adding additional, multi-byte specific,
    checks that can trigger buffer reallocation.
    

Temporary fix

  • Enable 'Allow per-column mapping' in the sequential file stage.
