At first I changed the value of the query_cache_size.
I don't think so.
After
Increases the value of the Query_cache_limit.
and Max_heap_table_size.
and tmp_table_size values.
Because we use a lot of preprocessing statements in our stored procedures. And the result of the statement is very large.
At first my results:
Mysql> Show variables like ' max_heap_table_size ';
+---------------------------------+----------------------+
| variable_name | Value |
+---------------------------------+----------------------+
| Max_heap_table_size | 16777216 |
+---------------------------------+----------------------+

Mysql> Show variables like ' tmp_table_size ';
+---------------------------------+----------------------+
| variable_name | Value |
+---------------------------------+----------------------+
| Tmp_table_size | 16777216 |
+---------------------------------+----------------------+

I changed the my.cnf file.

Mysql> Show variables like ' max_heap_table_size ';

Of course we know that MySQL defaults to give us a few configurations, we can through other configuration file to make an adjustment, as follows.

1, My-small.ini is designed for small databases. This model should not be used for databases that contain some common items. The
2, My-medium.ini is designed for medium sized databases. If you are using Rhel in your enterprise, you may have significantly more physical memory than the minimum RAM requirement (256MB) for this operating system. This shows that if you have so much RAM memory available, you can naturally run other services on the same machine.
3, My-large.ini is designed for computers that are dedicated to one SQL database. Because it can use up to 512MB of memory for the database, at least 1GB of RAM is required on this type of system so that it can handle both the operating system and the database application.
4, My-huge.ini is designed for databases in the enterprise. Such databases require dedicated servers and more than 1GB or 1GB of RAM.
