MySQL Workbench: How to Keep the Connection Alive
November 9, 2023
MySQL Workbench is a unified visual tool for database architects, developers, and DBAs. It provides data modeling, SQL development, and comprehensive administration tools. This guide focuses on how to keep the connection alive in MySQL Workbench, ensuring uninterrupted work sessions and avoiding the hassle of frequent reconnections.
Understanding Connection Timeouts
Connection timeouts in MySQL Workbench occur when the server closes an idle connection after a certain period. This can interrupt workflows and require frequent reconnections, which can be frustrating.
Configuring Server Settings
Edit the MySQL Configuration File: Locate and open the
my.ini(Windows) file in a text editor. This file is typically found in the MySQL installation directory.
wait_timeout: The number of seconds the server waits for activity on a non-interactive connection before closing it.
interactive_timeout: Similar to
wait_timeout, but for interactive connections like those used by MySQL Workbench.
Restart MySQL Service: After editing, restart the MySQL service to apply the changes.
Adjusting Workbench Preferences
Open MySQL Workbench Preferences: Launch MySQL Workbench, and navigate to
Edit > Preferences(Linux/Windows) or
MySQL Workbench > Preferences(macOS).
Configure SQL Editor Settings:
- Navigate to the
- Locate the option
DBMS connection keep-alive interval (in seconds).
- Set a suitable value (e.g.,
600for 10 minutes).
- This setting sends a simple query to the server at specified intervals to keep the connection active.
- Navigate to the
Write a Keep-Alive Script: Create a small SQL script with a simple query (like
SELECT 1;) and schedule it to run at regular intervals.
- This approach is similar to setting the keep-alive interval but offers more control over the query and timing.
Leveraging External Tools
If MySQL Workbench settings alone are not sufficient, consider using external tools or scripts that periodically interact with the database to prevent timeouts.
- Use External Keep-Alive Tools: Some third-party tools can send queries to your MySQL server at regular intervals to keep connections alive.
- Automate Connection Refreshes: Write a simple script in your preferred programming language to connect to the database and execute a query periodically.
Keeping your MySQL Workbench connection alive is essential for a smooth and uninterrupted workflow. By configuring server and Workbench settings, and optionally using external tools or scripts, you can prevent frequent disconnections due to timeouts. Remember, the key is to balance between server performance and the convenience of a persistent connection.
