How It Affects Your App
MySQL 1401 ER_XAER_RMERR indicates that an error occurred during a distributed transaction. This can have a significant impact on an application, as it can cause data inconsistency and data loss. It can also lead to application downtime, as the application may need to be restarted in order to recover from the error. Additionally, it can cause a decrease in user confidence, as users may not be able to trust the application to store their data reliably.
How To Fix
1. Check the error log for the MySQL 1401 error. This can be done by running the following command:
mysql> SHOW GLOBAL VARIABLES LIKE 'log_error';
2. Check the max_allowed_packet variable. This can be done by running the following command:
mysql> SHOW GLOBAL VARIABLES LIKE 'max_allowed_packet';
3. Increase the max_allowed_packet variable if it is lower than the size of the packet that is causing the error. This can be done by running the following command:
mysql> SET GLOBAL max_allowed_packet=1073741824;
4. Restart the MySQL server. This can be done by running the following command:
sudo service mysql restart
5. Use an automated database observability tool to monitor and fix the MySQL 1401 in question. Automated database observability tools can help identify and diagnose MySQL errors quickly and accurately. They can also provide real-time insights into the performance of the database, allowing for proactive monitoring and troubleshooting.
