Download Db2 JDBC Driver
What Is a JDBC Driver?
A JDBC driver is a Java library file (.jar) that enables Java applications — including DbSchema — to communicate with a database over a standard API. The driver translates generic JDBC calls into the network protocol understood by Db2, so you never have to write low-level socket code. Drivers are typically distributed by the database vendor or as open-source projects.
Understanding the JDBC URL
Every JDBC driver identifies the target database through a connection URL. The URL encodes the hostname, port, database name, and any driver-specific parameters as a single string. The exact syntax varies per driver — the details for Db2 are listed in the section below.

IBM Db2 is a robust enterprise relational database available on Linux, Windows, z/OS (mainframe), and IBM i (AS/400). It is commonly used in financial institutions and enterprise ERP systems that require high availability, advanced SQL features, and deep IBM ecosystem integration.
IBM Db2 JDBC Driver Details
- Required File(s): db2jcc.jar, db2jcc4.jar, db2jcc_license_cu.jar (optional)

The driver archive is a zip file. Extract it and load the .jar files using DbSchema's Driver Manager.
DbSchema and IBM Db2
DbSchema connects to Db2 on all platforms using the IBM JDBC driver and renders complex schemas with multi-table joins and referential integrity constraints as navigable ER diagrams. Use the SQL Editor's autocomplete to write Db2-specific syntax including recursive CTEs and OLAP functions.

Explore Db2 Visually with DbSchema
Once the JDBC driver is configured, DbSchema connects to your Db2 database and gives you a full graphical workbench — no command-line required. Available as a free Community Edition and a full-featured PRO Edition. No registration needed to get started.
Interactive ER Diagrams
Reverse-engineer your Db2 schema into a drag-and-drop ER diagram. Arrange tables visually, add new columns, define foreign keys, and let DbSchema generate the DDL — all without writing SQL by hand.
Visual Query Builder
Compose Db2 queries by clicking on tables and columns — no SQL knowledge required. Add joins, filters, groupings, and aggregations through a point-and-click interface, then copy the generated SQL or run it directly against the live database.
Relational Data Explorer
Browse Db2 table data and follow foreign key relationships across tables in a single view. Edit cells inline, filter rows, and paginate through large datasets — all without leaving the explorer.
Schema Synchronization
Compare your Db2 schema across development, staging, and production environments. DbSchema generates the exact ALTER statements needed to close the gap and lets you review every change before executing — reducing the risk of unintended schema drift.
SQL Editor
Write and execute Db2 queries in the integrated SQL editor with schema-aware autocomplete, syntax highlighting, and instant result display. Run scripts, inspect execution plans, and export results to CSV or JSON from a single interface.
HTML Schema Documentation
Generate a static HTML site documenting every table, column, type, index, and relationship in your Db2 schema. Share it with your team or embed it in your project wiki — no extra tooling required.
