How It Affects Your App
MySQL 1197 ER_TRANS_CACHE_FULL indicates that the transaction cache is full and no more transactions can be cached. This can cause the application to become unresponsive or slow down significantly as it is unable to process any more transactions. This can lead to a decrease in user experience and a decrease in productivity. Additionally, the application may be unable to complete any more transactions until the cache is cleared.
How To Fix
1. Check the error log for the MySQL 1197 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 processes are running that could be causing the issue:
$ mysqladmin -u root -p processlist
4. Check the MySQL user privileges to see if any users have been granted too many privileges:
$ mysql -u root -p -e "SELECT User, Host, Password FROM mysql.user;"
5. Check the MySQL database tables for any corruptions:
$ mysqlcheck -u root -p --all-databases
6. Restart the MySQL service to apply any changes:
$ service mysql restart
