Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All users of IBM Integration Bus v10 and IBM App Connect
    Enterprise v11 using the FileOutput Node to transfer files using
    SFTP.
    
    
    Platforms affected:
    z/OS, MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    When using the FileOutput node in SFTP mode, it is possible for
    a Java exception to occur and roll back the flow despite having
    successfully transferred the file. This can happen when the
    remote server unexpectedly closes the SFTP connection after the
    file has been sent.
    

Problem conclusion

  • The FileOutput node will now ignore such Java exceptions once
    the file has been successfully transferred.
