Maven releaseLocks

releaseLocks removes the specific Liquibase lock record from the DATABASECHANGELOGLOCK table in the needed database.

Uses

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

Maven configuration

You can configure Liquibase Maven in multiple ways. You can pass arguments like <changeLogFile> in Maven directly in your pom.xml file, in a liquibase.properties file referenced in your POM, as environment variables, or as JVM system properties.

Tip: For more information about the Maven configuration, see Configuring Maven.

Running the releaseLocks Maven goal

Running the releaseLocks goal requires a Maven project to be implemented.

To run the goal, type the following in your command prompt:

mvn liquibase:releaseLocks

When successful, the releaseLocks goal produces the following output:

[INFO] SELECT MD5SUM FROM DATABASECHANGELOG WHERE MD5SUM IS NOT NULL AND ROWNUM=1
[INFO] SELECT COUNT(*) FROM DATABASECHANGELOGLOCK
