How It Affects Your App
MySQL 1705 ER_STMT_CACHE_FULL indicates that the statement cache is full and no more statements can be cached. This can have a significant impact on an application's performance, as the statement cache is used to store prepared statements and their execution plans. Without the statement cache, the application must parse and optimize each statement every time it is executed, which can lead to slower performance. Additionally, the application may experience increased latency due to the extra time needed to parse and optimize each statement.
How To Fix
1. Check the error log for the MySQL 1705 error. This can be done by running the following command:
mysql> SHOW GLOBAL VARIABLES LIKE 'log_error';
2. Check the MySQL configuration file for any misconfigurations. This can be done by running the following command:
mysql> SHOW VARIABLES LIKE '%config_file%';
3. Check the MySQL server version. This can be done by running the following command:
mysql> SELECT VERSION();
4. Check the MySQL server status. This can be done by running the following command:
mysql> SHOW GLOBAL STATUS;
5. Check the MySQL server process list. This can be done by running the following command:
mysql> SHOW PROCESSLIST;
6. Check the MySQL server variables. This can be done by running the following command:
mysql> SHOW GLOBAL VARIABLES;
7. Check the MySQL server log files. This can be done by running the following command:
mysql> SHOW GLOBAL VARIABLES LIKE 'log_error';
8. Check the MySQL server privileges. This can be done by running the following command:
mysql> SHOW GRANTS;
9. Check the MySQL server connections. This can be done by running the following command:
mysql> SHOW PROCESSLIST;
10. Finally, it is recommended to use an automated database observability tool to monitor and fix the MySQL 1705 in question. This tool can provide real-time insights into the performance and health of the database, as well as alerting when any issues arise. This can help to quickly identify and fix any issues that may arise, such as the MySQL 1705 error.
