Question

我正在将我的应用程序部署到一个Docker容器中，在Webspehre liberty服务器上作为EAR文件。

但是，当应用程序运行时，它无法连接到我们尝试通过Websphere自由的server.xml中定义的jndi查找连接的另一台主机上运行的Oracle数据库。

<dataSource id="oracle" jndiName="jdbc/QADBApp" type="javax.sql.Datasource">

<jdbcDriver libraryRef="OracleJDBCLib"/>

<properties.oracle URL="jdbc:oracle:thin:@//xyz.mycomany.com:1521/prexyz" username="****" password="****" />

我们能够从容器内部ping服务器并获得响应，但在运行时，它无法建立数据库连接。

注意： - Oracle DB不是容器化的。我们只是试图通过jndi查找建立连接，如上所述。

以下是错误消息。在这种情况下，有没有人可以帮助如何连接数据库？提前感谢!!

你可以尝试使用ip地址而不是xyz.mycomany.com:1521吗？这肯定是一个网络问题，你可能想要通过https://docs.docker.com/engine/userguide/networking/default_network/ 您也可以在容器cat / etc / hosts中尝试它应该列出你要连接的ip /机器。

无法使用Docker Container连接到Oracle数据库
