診断
次の SQL クエリを使い、Confluence データベースで各ディレクトリの list_index を確認します。
SELECT * FROM cwd_app_dir_mapping ORDER BY 5;
This error can also occur when the cwd_application and/or cwd_app_dir_mapping tables are empty after a failed XML import. If this is the case, please follow Unable to Log In to Confluence.
原因
This problem occurs if the list index of your directories is not incremental (0,1,2..), or if the cwd_app_dir_mapping the table does not include a directory with a list-index of 0.
ソリューション
- Confluence をシャットダウンします。
cwd_app_dir_mappingテーブルを更新し、ディレクトリのlist_indexが適切な順序 (0、1、2、...) になるようにします。次の SQL クエリを使用できます。UPDATE cwd_app_dir_mapping SET LIST_INDEX=0 WHERE ID=<first_id>; UPDATE cwd_app_dir_mapping SET LIST_INDEX=1 WHERE ID=<second_id>; UPDATE cwd_app_dir_mapping SET LIST_INDEX=2 WHERE ID=<third_id>;- Confluence を再起動します。
データベースの変更を行う場合は必ず事前にバックアップを取得してください。可能な場合は、まずステージング サーバーで SQL コマンドの変更、挿入、更新、または削除を行うようにします。
