5.2 About the Liquibase User Interface
In the Liquibase page, the card at the top displays the Liquibase status. The deployments are displayed as cards below, as shown in the following figure.
Liquibase Status
Liquibase runs only one deployment at a time. When there is no deployment running, the top Liquibase card indicates that Liquibase is currently unlocked and displays the ID of the last deployment.
If there is a deployment running at the time, the card indicates that Liquibase is locked, and displays the name of the resource blocking it and the time at which the deployment started.
Deployments
The card for each deployment provides details such as the schema, deployment id, start and complete deployment date and time, and number of changesets run in the deployment. To open a specific deployment page, click the title of the card, or click Open Deployment Changes in the context menu.

Changesets
In a deployment page, the changesets that have been run for that specific deployment is displayed below. The Current Deployment card at the top shows the deployment to which the changesets belong.
Each changeset card displays the changeset name, the date and time when the changeset started deploying, and the schema where the change was deployed.
The context menu for a changeset consists of the following options:
- Previous Object State XML: Displays an XML showing the state of the object (table, procedure) before the changeset was applied. If the object did not exist previously on the database (example, a table that was created in the deployment ), the following message is displayed: xml code not available....
- Show Executed SQL: Displays the SQL code that was executed when the changeset was deployed.
