MySQL 1844

This error occurs when statement-based replication is enabled but no replication tables exist. MySQL 1844 indicates that statement-based replication cannot be used without replication tables.

How It Affects Your App

This error indicates that the application is attempting to replicate a statement that is not supported in the current binary log format. This can cause replication to fail, resulting in data loss or corruption. Additionally, the application may be unable to access certain tables, as the binary log format does not support replication of those tables. This can lead to unexpected errors or unexpected behavior in the application.

How To Fix

1. Check the error log for the MySQL 1844 error:
$ tail -f /var/log/mysql/error.log
2. Check the MySQL configuration file for any misconfigurations:
$ cat /etc/mysql/my.cnf
3. Check the MySQL user privileges:
$ mysql -u root -p
mysql> SELECT User, Host, Password FROM mysql.user;
4. Check the MySQL database tables for any corruptions:
$ mysqlcheck -u root -p --all-databases
5. Check the MySQL server status:
$ mysqladmin -u root -p status
6. Restart the MySQL server:
$ service mysql restart
7. Use an automated database observability tool to monitor and fix the MySQL 1844 in question. Automated database observability tools can provide real-time insights into the performance and health of the database, allowing for quick and easy identification of any issues. Additionally, these tools can provide automated alerts and notifications when any issues arise, allowing for quick and easy resolution of the issue.
