Question

我正在尝试部署debezium CDC连接器以从Oracle DB捕获数据。我们已经准备好了Oracle DB和Xstream连接器。

我遇到以下异常：

我已验证/usr/lib文件夹中包含ocijdbc11.dll文件。我也尝试将文件复制到/lib，但是遇到相同的错误。

我遇到了这个问题。首先去oracle下载“ instantclient” instantclient download

解压缩------相信您已将ojdbc.jar和xtream.jar复制到kafka lib。

然后添加环境变量

添加：

vim /etc/profile

保存---- wq！

ohhhhhh，记住---资源exprot LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/you download file addr/libocijdbc11.so

再次运行

Debezium CDC连接器在java.library.path中说没有ocijdbc11
