How It Affects Your App
The impact of MySQL 1520 ER_REORG_OUTSIDE_RANGE on an application is that it prevents the application from reorganizing tables outside of the range of the table. This can cause the application to be unable to perform certain operations, such as adding or deleting columns, or reorganizing the table structure. This can lead to errors in the application, as well as decreased performance due to the inability to reorganize the table. Additionally, it can lead to data integrity issues, as the application may not be able to properly store or retrieve data from the table.
How To Fix
1. Check the error log for the MySQL 1520 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 process list to see if any queries are running for an extended period of time:
$ mysqladmin -u root -p processlist
4. Check the MySQL status to see if there are any issues with the server:
$ mysqladmin -u root -p status
5. Check the MySQL variables to see if any of them are set to an incorrect value:
$ mysqladmin -u root -p variables
6. Check the MySQL user privileges to see if any of them are set to an incorrect value:
$ mysql -u root -p -e "SELECT * FROM mysql.user;"
7. Check the MySQL database tables to see if any of them are corrupted:
$ mysqlcheck -u root -p --all-databases
8. If the issue persists, restart the MySQL server:
$ service mysql restart
9. If the issue still persists, consider using an automated database observability tool to monitor and fix the MySQL 1520 in question. Automated database observability tools can provide real-time insights into the performance and health of the database, allowing for quick and easy troubleshooting and resolution of issues.
