配置 Pentaho 數據集成以連接到 Oracle DB

Question

我已經使用 DB、用戶配置了 Oracle VirtualBox 並填充了一個小 DB。 在同一台機器上，我安裝了 Pentaho Data-Integration(Spoon)、JDBC 驅動程序，我正在嘗試創建與 Oracle DB 的連接，但沒有成功。 這是我輸入憑據/數據的地方：

主機名：本地主機

數據庫名稱：(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=ORCL)))

端口號：1521

用戶名: SYSTEM

密碼：甲骨文

這是錯誤消息：

如何配置它以將 Pentaho/Spoon 連接到 Oracle DB？ oracle DB 似乎工作正常，我也嘗試過使用我創建的其他用戶/數據庫，但結果是一樣的。

Answer 1

通過從連接窗口中刪除“主機名”和“端口號”詳細信息，我能夠解決同樣的問題。 只留下“數據庫名稱”字符串。

Answer 2

我有一個類似的問題。 可以為客戶端工具以這種方式解決它，但不能為點菜服務器解決。

我用 JNDI 連接修復了它。

把它放在你的 pdi\\simple-jdni\\jdbc.properties

mydb/type=javax.sql.DataSource
mydb/driver=oracle.jdbc.driver.OracleDriver
mydb/url=jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS(PROTOCOL=TCP)(HOST=myhost)(PORT=myport)))(CONNECT_DATA=(SERVICE_NAME=myservicename)))
mydb/user=myuser
mydb/password=mypassword

以及您的 repositories.xml 中的此連接：

<connection>
<name>JNDI</name>
<server>myserver</server>
<type>ORACLE</type>
<access>JNDI</access>
<database>mydb</database>
<port>myport</port>
<username>myuser</username>
<password>mypassword</password>
<servername/>
<data_tablespace/>
<index_tablespace/>

</attributes>

Answer 3

添加

(FAILOVER_MODE=(type=select)(method=basic)(retries=20)(delay=3))))

到字符串的末尾為我們解決了它。
