無法創建PoolableConnectionFactory（Io異常：網絡適配器無法建立連接）

Question

您好我有一個彈簧應用程序的上述異常，我試圖連接到羣集的Oracle數據庫，但即使我嘗試連接到單個實例仍然具有相同的異常。

的bean定義是這樣的：

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> 
      <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" /> 
      <property name="url" value="jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=host_ip1)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=host_ip2)(PORT=1521)))(LOAD_BALANCE=ON)(FAILOVER=ON)(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=db)))" /> 
      <property name="username" value="username" /> 
      <property name="password" value="password" /> 
      <property name="initialSize" value="10" /> 
    </bean> 

完整的堆棧跟蹤是：

Answer 1

我不得不去尋找與安裝此f的oracle版本兼容的ojdbc ixed我的問題，我的壞想着一個ojdbc會爲所有工作

Answer 2

只需檢查tsnnames.ora和listener.ora文件。它不應該有本地主機作爲服務器。將其更改爲主機名。

像tnsnames.ora中

LISTENER_ORCL = 
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521)) 

由主機名localhost替換。

Answer 3

在登錄時，我還在使用Oracle 10g Express Edition和基於Spring和CAS的應用程序時遇到錯誤「Error preloading the connection pool」。

我的基於CAS的應用程序的類路徑中只有classes12.jar，在類路徑中放置ojdbc14.jar已解決了我的問題。

Answer 4

我有同樣的錯誤，並最終通過升級我的Oracle ojdbc驅動程序與Oracle數據庫版本

Answer 5

我有一個類似的錯誤在Tomcat 8.0/MySQL的兼容版本解決它。將jdbc url值從localhost更改爲127.0.0.1解決了問題。
