The following steps will delete all follower and followee entries that are no longer exist in cwd_user table
- Confluence をシャットダウンします。
- Create a backup of Confluence database for safety precaution
Only if you are on Confluence 5.1.x or earlier:
Execute the following SQL queriesDELETE FROM FOLLOW_CONNECTIONS WHERE LOWER(FOLLOWER) NOT IN (SELECT lower_user_name FROM cwd_user); DELETE FROM FOLLOW_CONNECTIONS WHERE LOWER(FOLLOWEE) NOT IN (SELECT lower_user_name FROM cwd_user);Only if you are on Confluence 5.2.x or later:
Execute the following SQL queriesDELETE FROM FOLLOW_CONNECTIONS WHERE FOLLOWER NOT IN (SELECT user_key FROM user_mapping WHERE LOWER(username) IN (SELECT lower_user_name FROM cwd_user)); DELETE FROM FOLLOW_CONNECTIONS WHERE FOLLOWEE NOT IN (SELECT user_key FROM user_mapping WHERE LOWER(username) IN (SELECT lower_user_name FROM cwd_user));- Confluence を再起動します。
