主なエラーは、以下です。

com.atlassian.migration.agent.store.jpa.impl.LiquibaseSchemaUpgrader.upgrade(LiquibaseSchemaUpgrader.java:35) caused by: liquibase.exception.LockException: Could not acquire change log lock.

原因

この問題は MIG_DB_CHANGELOG_LOCK  テーブルがリリース ロック情報で更新されておらず、アップグレード後にデータベース スキーマを移行しようとしている間に Confluence が強制終了したことが原因と考えられます。 

(info) The MIG_DB_CHANGELOG_LOCK table is related to the Cloud Migration Assistant for Confluence plugin which is bundled by default since Confluence 6.14.

ソリューション

この問題を解決するには、以下の回避策に従ってください。

  • Confluence データベースで以下の SQL クエリを実行して、手動でロックを解除します。 

Postgres 構文 
UPDATE MIG_DB_CHANGELOG_LOCK SET LOCKED=false, LOCKGRANTED=null, LOCKEDBY=null where ID=1;
MySQL、SQLServer、および、Oracle 構文 
UPDATE MIG_DB_CHANGELOG_LOCK SET LOCKED=0, LOCKGRANTED=null, LOCKEDBY=null where ID=1;
  • Confluence を再起動します。
