【问题描述】：

我在 kafka 连接中使用 debezium oracle 连接器。启动连接器时出现以下错误，

我指的是oracle设置和连接器配置的链接，

**https://debezium.io/documentation/reference/connectors/oracle.html#setting-up-oracle**

connector-configuration.properties

name=debeziumoraclesource
connector.class=io.debezium.connector.oracle.OracleConnector
database.hostname=**.*.**.**
database.port=1521
database.user=username
database.password=password
database.dbname=CDBNAME
database.server.name=**.*.**.**
tasks.max=1
database.pdb.name=PDBNAME
database.history.kafka.bootstrap.servers=kafka:9092
database.history.kafka.topic=history.ENTITY_GROUP_PARAMETER_VALUES
database.connection.adaptor=logminer
snapshot.mode=initial
table.include.list=schema.ENTITY_GROUP_PARAMETER_VALUES

我还下载了 ojdbc8.jar 并放在 kafka/libs 文件夹中。我尝试使用不同版本的 jars，如 ojdbc10 和不同版本的 ojdbc8。没有什么帮助我。还有一点我正在使用 oracle19c。请帮我解决这个问题。在此先感谢。

【参考方案1】：

使用带有所有依赖项的 OJDBC6.jar 帮助我解决了这个问题。最重要的是，我将罐子放在 connector lib 文件夹中。
