Added oracle docker files.

[subkanthi]

Setup Oracle using the enterprise image. You need an account setup to download the enterprise image from container registry(Oracle)
https://debezium.io/blog/2022/09/30/debezium-oracle-series-part-1/

Start oracle,clickhouse using docker-compose
docker compose -f docker-compose-oracle.yml up

If you are connecting to a diffferent oracle/clickhouse, update the following fields in config_oracle.yml before starting sink connector.

Oracle

database.hostname: "localhost"
database.port: "1521"

database.dbname: "ORCLCDB"
database.pdb.name: "ORCLPDB1"

#database.pdb.name: "ORCLPDB1"

database.user: "c##dbzuser"

database.password: "dbz"

database.connection.url: "jdbc:oracle:thin:@//localhost:1521/ORCLCDB"

database.server.name: "dbserver1"
database.connection.adapter: "logminer"

ClickHouse
in the jdbc.url, change localhost if its not running locally

clickhouse.server.url: "localhost"

clickhouse.server.user: "root"

clickhouse.server.password: "root"

clickhouse.server.port: "8123"

offset.storage.jdbc.url: "jdbc:clickhouse://localhost:8123/altinity_sink_connector"
schema.history.internal.jdbc.url: "jdbc:clickhouse://localhost:8123/altinity_sink_connector"

NOTE: Currently DDL is not supported, the default is MySQL ANTLR parser , we need to integrate Debezium Oracle ANTLR parser. So the tables have to be manually created in ClickHouse.

Start sink connector JAR.

java -jar clickhouse-debezium-embedded-0.0.4.jar ../docker/config_oracle.yml
