release-locks

release-locks removes the specific Liquibase lock record from the DATABASECHANGELOGLOCK table in the needed database.

Uses

release-locks is typically used when there is an interruption with the Liquibase process during deployment resulting from the DATABASECHANGELOGLOCK table being in a locked state.

Syntax

To run the release-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 release-locks command:

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

Command arguments

Tip: For best results, specify all commands and parameters in the --kebab-case format in the CLI. If your preference is camelCase, it also works in the CLI.
