How It Affects Your App
MySQL 1638 WARN_NON_ASCII_SEPARATOR_NOT_IMPLEMENTED indicates that the application is attempting to use a non-ASCII character as a separator. This can cause issues with the application's ability to properly parse data, as the non-ASCII character may not be recognized by the database. This can lead to data being incorrectly parsed, resulting in incorrect results or errors. Additionally, it can cause performance issues as the database may need to spend more time attempting to parse the data.
How To Fix
1. Check the error log for the MySQL 1638 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 version and make sure it is up to date:
$ mysql --version
4. Check the MySQL user privileges and make sure they are set correctly:
$ mysql -u root -p
mysql> SHOW GRANTS FOR 'root'@'localhost';
5. Check the MySQL database tables and make sure they are not corrupted:
$ mysqlcheck -u root -p --all-databases
6. Restart the MySQL service:
$ sudo service mysql restart
7. Use an automated database observability tool to monitor and fix the MySQL 1638 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.
