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


listLocks 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.

listLocks 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.
