list-locks

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. For more information, see Create and Configure a 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

Command parameters

Attribute Definition Requirement

--url=<string>

The JDBC database connection URL. See Using JDBC URL in Liquibase.

 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.

Tip: In Liquibase v4.23.0+, camelCase for defaultSchemaName works successfully. If you are on an earlier version, camelCase may not work as expected.

Note: The syntax liquibase.command.defaultSchemaName is valid for v4.19.0+. For prior versions, use defaultSchemaName.

 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.
