  • Qlogic FC HBA 編譯問題追蹤
    • 2.6.26 編譯錯誤 Log 檔
    • 可以看到 2.6.26 版本的 scsi_cmnd.h 已經把原有 2.6.18 版本的 66 行 request_bufflen、 69 行 request_buffer 、 72 行 use_sg 的 structure data member 拿掉,並新增 struct scsi_data_buffer sdb 的定義。
      • include/scsi/scsi_cmnd.h

    • 先前在 LinuxWorld 有看過 Demo,只是當時對於 Data Integration 並沒有很深刻的體認。
    • 近期因為海科中心計畫,在業界也遇到一些組織內資料庫整合的問題,慢慢覺得資料庫整合是一件困難的事情,需要有好的工具輔助。

      We deal with XML, we deal with flat files, we deal with different databases, 
      so we need a variety in terms of connectivity and the ability to map the data flows. 
      The connectors allow you to process and orchestrate data moving from one system to the next.
