Question

我正在尝试使用在Windows 10计算机上的docker容器中运行的ksqlDB连接到外部Oracle数据库。我已经阅读了ksqlDB网站上提到的教程，并设法使用下面的docker-compose文件运行ksqlDB。现在，我需要创建JDBC连接器以连接到EXTERNAL ORACLE数据库（不在容器内）。由于大多数可用的教程都在容器内部运行的Postgres数据库上，所以我对与外部数据库的连接有些困惑。我在下面提到了一个用于连接器的模板。请建议如何根据我的Oracle数据库配置对其进行修改？

假设，Oracle数据库配置如下所述在我的本地计算机上：

HOST = dev-db.com
PORT = 1522
SERVICE NAME = dv06.db.com

Postgres的连接器模板：

CREATE SOURCE CONNECTOR jdbc_source WITH (
  'connector.class'          = 'io.confluent.connect.jdbc.JdbcSourceConnector',
  'connection.url'           = 'jdbc:postgresql://postgres:5432/postgres',
  'connection.user'          = 'postgres',
  'connection.password'      = 'password',
  'topic.prefix'             = 'jdbc_',
  'table.whitelist'          = 'driver_profiles',
  'mode'                     = 'incrementing',
  'numeric.mapping'          = 'best_fit',
  'incrementing.column.name' = 'driver_id',
  'key'                      = 'driver_id',
  'key.converter'            = 'org.apache.kafka.connect.converters.IntegerConverter');

如果您需要知道要使用的cpack的格式，那么Oracle文档是您的朋友：https://docs.oracle.com/database/121/TDPJD/getconn.htm#TDPJD138

例如，以下可能适用于您：

connection.url

当然，您还需要更新用户名，密码以及有关要使用连接器导入的表及其键的其他详细信息。
