Using Liquibase with DB2 LUW

DB2 LUW (DB2 for Linux, Unix, and Windows) is a cross-platform database management system created by IBM. For more information, see DB2 Documentation.

Supported versions

  • 11.5.7+

Verification level

Guaranteed: All applicable Liquibase Open Source and Liquibase Pro functionality works with this database. Verified by automated and real-world testing from Liquibase. The Liquibase support team provides best-effort usage, bug-fix, and prioritized feature request support to Commercial users.

Note: A database's verification level indicates how well it works with different features in Liquibase and across different products, such as Liquibase Open Source and Liquibase Pro. For more information, see Liquibase Database Tutorials.

Prerequisites

Install drivers

To use Liquibase and DB2 LUW, you need two files:

The latest version of Liquibase has a pre-installed driver for this database in the liquibase/internal/lib directory. Read more: Adding and Updating Liquibase Drivers.

If you use Maven, you must include the driver JAR as a dependency in your pom.xml file. Read more: Configuring Liquibase Attributes in your Maven POM File.

<dependency>
    <groupId>com.ibm.db2</groupId>
    <artifactId>jcc</artifactId>
    <version>11.5.7.0</version>
</dependency>
<dependency>
    <groupId>org.liquibase.ext</groupId>
    <artifactId>liquibase-db2i</artifactId>
    <version>4.17.2</version>
</dependency>

Test your connection

  1. Ensure your DB2 LUW database is configured. See Verifying the Installation for more information.
  2. Specify the database URL in the Liquibase properties file. Liquibase does not parse the URL. You can either specify the full database connection string or specify the URL using your database's standard JDBC format:
  3. url: jdbc:db2://<server_name>:<port>/<db_name>

    Tip: To apply a Liquibase Pro key to your project, add the following property to the Liquibase properties file: liquibaseProLicenseKey: <paste code here>

  1. Create a text file called changelog (.xml, .sql, .json, or .yaml) in your project directory and add a changeset.
  2. Navigate to your project folder in the CLI and run the Liquibase status command to see whether the connection is successful:
  3. liquibase --username=test --password=test --changelog-file=<changelog.xml> status

    Note: You can pass arguments in the CLI or keep them in the Liquibase properties file.

  4. Inspect the SQL with the update-sql command. Then make changes to your database with the update command.
  5. liquibase --changelog-file=<changelog.xml> update-sql
    liquibase --changelog-file=<changelog.xml> update
  6. From a database UI tool, ensure that your database contains the test_table you added along with the DATABASECHANGELOG table and DATABASECHANGELOGLOCK table.
