How It Affects Your App
MySQL 1280 ER_WRONG_NAME_FOR_INDEX indicates that an index name is invalid or too long. This can cause the application to fail when attempting to create or modify an index. It can also lead to unexpected results when querying the database, as the index may not be used correctly. This can lead to incorrect data being returned or incorrect calculations being made. In addition, it can cause performance issues as the query optimizer may not be able to use the index correctly.
How To Fix
1. Check the error log for the MySQL 1280 instance to identify the root cause of the issue.
mysql> SHOW GLOBAL VARIABLES LIKE 'log_error';
+---------------+-----------------------------------------+
| Variable_name | Value |
+---------------+-----------------------------------------+
| log_error | /var/lib/mysql/mysql-error.log |
+---------------+-----------------------------------------+
2. Check the error log for the MySQL 1280 instance to identify the root cause of the issue.
$ tail -f /var/lib/mysql/mysql-error.log
2020-08-01T12:00:00 [ERROR] InnoDB: Unable to allocate memory of size 8388608.
2020-08-01T12:00:00 [ERROR] InnoDB: Cannot allocate memory for the buffer pool
2020-08-01T12:00:00 [ERROR] InnoDB: Fatal error: cannot allocate memory for the buffer pool
3. Increase the memory allocated to the MySQL 1280 instance.
mysql> SET GLOBAL innodb_buffer_pool_size=16M;
Query OK, 0 rows affected (0.00 sec)
4. Restart the MySQL 1280 instance.
$ sudo service mysql restart
5. Use an automated database observability tool to monitor and fix the MySQL 1280 instance. Automated database observability tools can help identify and diagnose issues quickly, as well as provide insights into the performance of the database. They can also provide alerts when issues arise, allowing for quick resolution.
