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

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 Oracle DB 和 Xstream 连接器。

我遇到以下异常：

我已验证 /usr/lib 文件夹中有 ocijdbc11.dll 文件。我也尝试将文件复制到 /lib，但我遇到了同样的错误。

Answer 1

我遇到了这个问题。先去oracle下载'instantclient' instantclient download

unzip------相信你已经将ojdbc.jar和xtream.jar复制到kafka lib.

然后添加环境变量

vim /etc/profile

添加：

exprot LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/you download file addr/libocijdbc11.so

保存----wq!

ohhhhhh，记住---资源/etc/profile

运行再一次
