Question

我当前正在使用Liquibase Java API运行DDL脚本。整个脚本和相应的changeSet成功执行。但是，此执行之后，Liquibase会引发LockException。

错误日志如下，

根据该错误，以某种方式将IND_DEV（这是数据库用户名）附加到DATABASECHANGELOGLOCK表中。有谁知道这个问题可能是什么？

有时，如果更新应用程序突然停止，则锁将保持卡住状态。可能是由于被杀死的liquibase进程未释放其锁

然后跑步

UPDATE DATABASECHANGELOGLOCK SET LOCKED=0, LOCKGRANTED=null, LOCKEDBY=null;

针对数据库的帮助。

或者您可以简单地删除DATABASECHANGELOGLOCK表，它将重新创建。或您配置的任何更改日志锁名称。

创建数据库后，Liquibase锁定错误
