liquibase.exception.LockException: Could not acquire change log lock. Currently locked by...

Solution :

Open your database and find the table named 'Databasechangeloglock', check the content of the Locked column. If it is set to '1' in that case the above exception will be thrown. Try setting it to '0' and set content of the 'LOCKGRANT' and 'LOCKEDBY' to (null).

How databasechangeloglock and databasechangelog table used by liquibase?

Liquibase takes care of executing the query on the database while maintaining the list of queries executed and also maintaining the locks over the tables simultaneously. The two tables that are used by the liquibase for this purpose are : Databasechangeloglock : This table have following columns ID | LOCKED| LOCKGRANTED | LOCKEDBY. This maintains the locks information granted to the user. The primary purpose of this table is to make sure that two machines don't attempt to modify the data at the same time. Databasechangelog : This table have following columns ID | AUTHOR | FILENAME | DATEEXECUTED | ORDEREXECUTED | EXECTYPE | MD5SUM | DESCRIPTION | COMMENTS | TAG | LIQUIBASE This table maintains the list of the statements that are executed on the database.

Check for relative path.    - So now you have copied it and paste it in your new file where you are going to use the dhtmlx component and when you open your file you get this error and it becomes frustrating knowing that same thing is wo
