The changelog-lock-wait-time-in-minutes global parameter is an integer value that sets the amount of time Liquibase waits for a locked database to become available. The default value is 5.


The DATABASECHANGELOGLOCK table only allows a single instance of Liquibase to run at a time. This prevents conflicts between multiple developers working at the same time or multiple servers in a cluster that auto-run Liquibase on startup.

DATABASECHANGELOGLOCK has a column named LOCKED that is set to 1 while Liquibase is running and 0 otherwise. If you try to run Liquibase while the lock record is active, the following message is printed to STDOUT:

Waiting for changelog lock....

This message repeats until LOCKED is set to 0. If the amount of time specified in changelog-lock-wait-time-in-minutes passes and the lock is not released, Liquibase stops running.


Liquibase doesn’t automatically time out if a database update takes a long time to finish. If you need to run multiple database updates at once, and each of them takes a long time to complete, you can raise the value of changelog-lock-wait-time-in-minutes. This way, you don’t have to re-run commands that timed out.

If you need to limit system resources by halting processes in a "waiting" state, you can lower the value of changelog-lock-wait-time-in-minutes.


You can set this parameter in the following ways:

Option Syntax
Liquibase properties file
liquibase.changelogLockWaitTimeInMinutes: <int>
Global flow file argument (example)
      - type: liquibase
        command: update
        globalArgs: { changelog-lock-wait-time-in-minutes: "<int>" }
Global CLI parameter
 --changelog-lock-wait-time-in-minutes=<int> update

JVM system property (JAVA_OPTS Environment Variable)

Note: If you use Liquibase 4.3.5 or earlier, the syntax for this argument in the properties file or as a JVM system property is changeLogLockWaitTimeInMinutes instead of changelogLockWaitTimeInMinutes.
