list-locks

Last published July 28, 2025

list-locks returns the hostname, IP address, and the timestamp the Liquibase lock record was added to the DATABASECHANGELOGLOCK table.

Uses

list-locks is typically used when an error occurs during a database deployment. The error might indicate that there is a lock record in the DATABASECHANGELOGLOCK table by another user that is preventing Liquibase from applying changes to the specified database.

list-locks will read the DATABASECHANGELOGLOCK table and return a list that includes the hostname, IP address, and the timestamp the lock record was granted to the DATABASECHANGELOGLOCK table and determines the connections to the DATABASECHANGELOGLOCK table based on the database URL.

Syntax

To run the list-locks command, specify the driver, classpath, and URL in the Liquibase properties file. You can also specify these properties in your command line.

Then run the list-locks command:

liquibase list-locks --changelog-file=example-changelog.xml

Note: The username and password attributes are not required for connections and systems which use alternate means of authentication. Also, you can specify database credentials as part of the url attribute.

Command parameters

Attribute

Definition

Requirement

--url=<string>

The JDBC database connection URL.

Required

--changelog-file=<string>

The root changelog

Optional

--default-catalog-name=<string>

Name of the default catalog to use for the database connection

Optional

--default-schema-name=<string>

Name of the default schema to use for the database connection. If defaultSchemaName is set, then objects do not have to be fully qualified. This means you can refer to just mytable instead of myschema.mytable.

Note: In the properties file and JAVA_OPTS only: in 4.18.0 and earlier, specify this parameter using the syntax defaultSchemaName. In 4.19.0 and later, use the syntax liquibase.command.defaultSchemaName.

Note: In Liquibase 4.12.0 and later, you can use mixed-case schema names if you set --preserve-schema-case to true. However, in Liquibase 4.12.0–4.22.0, the Liquibase validator still throws a DatabaseException error if you specify a mixed-case value of defaultSchemaName. In 4.23.0 and later, the Liquibase validator accepts any casing.

Optional

--driver=<string>

The JDBC driver class

Optional

--driver-properties-file=<string>

The JDBC driver properties file

Optional

--password=<string>

Password to connect to the target database.
