About the Oracle JDBC driver

A JDBC driver is a Java .jar library that lets applications connect to Oracle. DbSchema uses JDBC to reverse engineer schemas, run SQL, and generate documentation. Driver files are usually published by the database vendor or an open-source project.

JDBC URL format

Host, port, database name, and SSL options are passed in a URL starting with jdbc:. Each Oracle driver uses its own syntax — see the connection details below.

The Oracle JDBC driver

Oracle Database is the industry-leading enterprise RDBMS, widely used in banking, healthcare, and government sectors. It supports advanced features like partitioning, PL/SQL stored procedures, RAC clustering, and pluggable databases (PDB/CDB).

The Oracle JDBC URL

Required File(s): ojdbc15.jar (For Java 1.5), ojdbc16.jar (For Java 1.6)
Java Driver Class: oracle.jdbc.OracleDriver
URL ( connect via SID ): jdbc:oracle:thin:@HOST[:PORT]:DB
URL ( connect via service name ): jdbc:oracle:thin:@//HOST[:PORT]/DB
Website: Oracle

Download Oracle JDBC Driver

The driver archive is a zip file. Extract it and load the .jar files using DbSchema's Driver Manager.

Thin Driver vs Oracle Client

The thin driver (oracle.jdbc.OracleDriver) does not require an Oracle client installation and works out of the box. Connect via SID (jdbc:oracle:thin:@host:port:SID) or service name (jdbc:oracle:thin:@//host:port/service). For Autonomous Database on Oracle Cloud, download the wallet and use the ojdbc-full.jar bundle which includes the required TLS certificates.

DbSchema and Oracle

DbSchema renders Oracle's multi-schema environments as tabbed diagrams, making it easy to navigate between large schema objects like tables, views, packages, and sequences. The Schema Synchronization feature generates Oracle-compatible DDL including sequence grants and constraint syntax.
