MySQL Workbench

5.3 Manage Server Connections

The Manage Server Connections dialog is another way to manage MySQL connections. This dialog is invoked by either clicking the manage connections icon () on the home screen or by selecting Database and then Manage Connections from the main menu. It can also be invoked from any of the wizards requiring access to a live database.

After the MySQL connection manager is launched, you are presented with the Connection tab of the Manage Server Connections dialog. The following figure shows the initial connection options for a standard TCP/IP connection.

Notes on MySQL Connection Manager


Simultaneous client connections: Opening a MySQL connection from the MySQL Workbench home screen opens a new connection tab in MySQL Workbench for that connection. Each of these tabs requires two MySQL connections to perform basic tasks, such schema discovery and SQL execution. Additionally, performing management related tasks, such as Server Status, requires two additional MySQL connections. Essentially, this means that each MySQL connection tab in MySQL Workbench requires four available connections to MySQL. For additional information about "Too many connection" related errors, see Too many connections.

This connection requirement doubles with each connection tab opened in MySQL Workbench, even if the two connection tabs point to the same MySQL server. SQL editor tabs share their connections, so having multiple SQL editor and SQL results tabs does not affect the number of required connections.
