我必須在db2dsdriver.cfg中執行哪些規範才能連接到aDB2數據庫？我得到SQL1532N錯誤

Question

我安裝了Python 3.4和ibm_db來連接到DB2數據庫;我在Python解釋器中看到安裝了ibm_db 2.0.7，但在連接到DB2數據庫時，我收到了SQL1532N錯誤消息，因此我認爲我需要配置db2dsdriver.cfg，並且爲此我得到了db2dsdriver.xsd文件，但是我沒有知道我必須改變什麼。我應該將所有「數據庫」更改爲我嘗試連接的DB2實例中數據庫的實際名稱？還有什麼我必須改變？

順便說一下，我的Windows 10中沒有安裝db2dsdriver.cfg，並且關於我認爲它是從db2dsdriver.xsd動態創建的一些信息，它位於Python34下的\cfg子目錄中。

Answer 1

的error message corresponding to SQL1532N寫着：

的db2dsdriver.cfg中的配置文件中包含數據庫別名 「數據庫別名」 多個條目。

這可能意味着你做有db2dsdriver.cfg一個副本standard locations之一。根據您安裝的驅動程序包，它可能在C:\ProgramData\IBM\DB2\<driver_copy_name or other path>\cfg之下。

.xsd文件描述了模式的配置文件，沒有必要編輯它。您需要找到實際的.cfg文件並從中刪除重複的數據庫記錄，只留下您需要的一個。
