You need additional files to use Liquibase with this database. Use the buttons above to navigate to the required downloads and extract them to your Liquibase /lib folder.

If you prefer, you can use environment variables to point to the directory where Liquibase is installed on your machine. You can set environment variables using your operating system's shell. The location of $LIQUIBASE_HOME will depend on where Liquibase was installed on your machine.

Note for Maven users: If you're running Liquibase using the Maven plugin using mvn liquibase: update, installing the extension with Maven ensures the right files are available and everything works together automatically. You can manage these extensions by adding them as dependencies in your project’s pom.xml file. Configuring Maven this way ensures that the necessary JAR files are retrieved from Maven Central during the build phase.

1. Log into your Oracle Cloud account.

2. Navigate to Autonomous Database and select DB Connection > Wallet Type > Download.

3. Enter a secure password for the Wallet and download the ZIP file to save the client security credentials.

4. Unzip the Wallet and place it somewhere safe in your file system to prevent unauthorized database access.

5. Navigate to the Wallet folder and update the ojdbc.properties file with the following:

• Comment out the oracle.net.wallet_location line.

• Set javax.net.ssl.trustStorePassword to the Wallet password that you entered to download the Wallet.

• Set javax.net.ssl.keyStorePassword to the Wallet password that you entered to download the Wallet.

#oracle.net.wallet_location=(SOURCE=(METHOD=FILE)(METHOD_DATA=(DIRECTORY=${TNS_ADMIN}))) javax.net.ssl.trustStore=${TNS_ADMIN}/truststore.jks javax.net.ssl.trustStorePassword=my_wallet_password javax.net.ssl.keyStore=${TNS_ADMIN}/keystore.jks javax.net.ssl.keyStorePassword=my_wallet_password

6. In the Wallet folder, open the sqlnet.ora and ensure that SSL_SERVER_DN_MATCH=yes.

7. Specify the database URL in the liquibase.properties file (defaults file), along with other properties you want to set a default value for. Liquibase does not parse the URL. You can either specify the full database connection string or specify the URL using your database's standard connection format:

url: jdbc:oracle:thin:@<database_name>_high?TNS_ADMIN=/path/to/Wallet_<database_name>

Note: If you use Windows, ensure the TNS_ADMIN path to your wallet folder includes double slashes in the URL property.

Example: url: jdbc:oracle:thin:@databaseName_high?TNS_ADMIN=path//to//Wallet_databaseName

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

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

If you already created a changelog using the init project command, you can use that instead of creating a new file. When adding onto an existing changelog, be sure to only add the changeset and to not duplicate the changelog header.

2. Navigate to your project folder in the CLI and run the Liquibase status command to see whether the connection is successful:

liquibase status --username=test --password=test --changelog-file=<changelog.xml>

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

If your connection is successful, you'll see a message like this:

4 changesets have not been applied to <your_connection_url> Liquibase command 'status' was executed successfully.

3. Inspect the deployment SQL with the update-sql command

liquibase update-sql --changelog-file=<changelog.xml>

If the SQL that Liquibase generates isn't what you expect, you should review your changelog file and make any necessary adjustments.

4. Then execute these changes to your database with the update command:

liquibase update --changelog-file=<changelog.xml>

If your update is successful, Liquibase runs each changeset and displays a summary message ending with:

Liquibase: Update has been successful. Liquibase command 'update' was executed successfully.

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