Using Liquibase with Oracle

Oracle Database is an object-relational database that offers market-leading performance, scalability, reliability, and security, both on-premises and in the cloud. For more information, see the Oracle documentation page.

Prerequisites

Install Drivers

To use Liquibase and Oracle, you need to have the JDBC driver JAR file.

Liquibase comes with a pre-installed driver for this database in the liquibase/internal/lib directory. For more information, see Adding and Updating Liquibase Drivers.

If you use Maven, you also need to download the driver JAR file and configure your Maven pom.xml file to use the local copy of the driver. For more information, see Configuring Liquibase Attributes in your Maven POM File. For example:

<dependency>
    <groupId>com.oracle.database.jdbc</groupId>
    <artifactId>ojdbc8</artifactId>
    <version>21.5.0.0</version>
</dependency>

Test Your Connection

For Liquibase and Oracle to work, you need to:

  1. Ensure Oracle is configured. See the following:
  1. Specify the database URL in the Liquibase properties file or as a parameter to the command in the CLI. See the following:

  1. Create a text file called changelog (.xml, .sql, .json, or .yaml) in your project directory and add a changeset.

<?xml version="1.0" encoding="UTF-8"?>
<databaseChangeLog
	xmlns="http://www.liquibase.org/xml/ns/dbchangelog"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <changeSet id="1" author="Liquibase">
    <createTable tableName="test_table">
           <column name="test_id" type="int">
                 <constraints primaryKey="true"/>
           </column>
           <column name="test_column" type="varchar"/>
    </createTable>
    </changeSet>
</databaseChangeLog>
-- liquibase formatted sql

-- changeset liquibase:1
CREATE TABLE test_table (test_id INT, test_column VARCHAR, PRIMARY KEY (test_id))

Tip: Formatted SQL changelogs generated from Liquibase versions before 4.2 might cause issues because of the lack of space after a double dash ( -- ). To fix this, add a space after the double dash. For example: -- liquibase formatted sql instead of --liquibase formatted sql and -- changeset myname:create-table instead of --changeset myname:create-table

databaseChangeLog:
   - changeSet:
       id: 1
       author: Liquibase
       changes:
       - createTable:
           columns:
           - column:
               name: test_column
               type: INT
               constraints:  
                   primaryKey:  true  
                   nullable:  false  
                   tableName: test_table

  1. Navigate to your project folder in the CLI and run the Liquibase status command to see whether the connection is successful. You can pass arguments in the CLI or keep them in the Liquibase properties file.
    2. liquibase --username=test --password=test --changelog-file=<changelog.xml> status
  2. Inspect the SQL with the update-sql command. Then make changes to your database with the update command.
    3. liquibase --changelog-file=<changelog.xml> update-sql
liquibase --changelog-file=<changelog.xml> update

From a database UI tool, ensure that your database contains the table you added along with the DATABASECHANGELOG table and DATABASECHANGELOGLOCK table.

Oracle Server

  • Specify the database URL in Liquibase properties file, as follows: 
    url: jdbc:oracle:thin:@<host>:<port>/<service_name>

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

Oracle on AWS RDS

Check the connection by using any standard SQL client application, including SQL*Plus, and running the following:

Linux, macOS, or Unix

sqlplus 'user_name@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=dns_name)(PORT=port))(CONNECT_DATA=(SID=database_name)))'

Windows

sqlplus user_name@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=dns_name)(PORT=port))(CONNECT_DATA=(SID=database_name)))

Note: user_name represents your DB instance administrator, and dns_name stands for your DB instance. Also, replace the port number and the Oracle SID with your values. The Oracle SID is the name of the DB instance's database that you specified when you created the DB instance.

Tip: The alternative way is to connect with Oracle SQL Developer.

You can find the connection information in the AWS Management Console:

  1. Sign in to the AWS Management Console and open the Amazon RDS console.
  2. In the upper-right corner of the console, choose the AWS Region of your DB instance.
  3. Find the DNS name and port number for your DB Instance:
    • Select Databases and choose the needed Oracle DB instance to display the instance details.
    • Select Connectivity & security. You will see all information under Endpoint & Port.

Note: To find the connection information using the AWS CLI, call the describe-db-instances command, as follows: aws rds describe-db-instances. In the output, you will see the Port line and the Address line containing the DNS name.

Specify the database URL in the Liquibase properties file, as follows:

url: jdbc:oracle:thin:@<endpoint>:<port>:<sid>

Example: url: jdbc:oracle:thin:@myrds.cz1j1vh9uvuo.us-east-1.rds.amazonaws.com:3306:orcl
