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.

Elements of the MySQL Connection Manager

Connection input fields:

• Connection Name: The name used to refer to this connection. This connection can then be selected from a list in other wizards requiring a connection.

• Connection Method: Method used to connect to the RDBMS.

  After you select a connection method, the fields available in the Parameters, SSL, and Advanced tabs change accordingly. For more information about these options and parameters, see the section describing each connection method.

Connection actions:

• New

  Opens a separate Manage Server Connections dialog to create a new connection. This dialog provides two tabs in addition to the Connection tab: Remote Management and System Profile

• Delete, Duplicate, Move Up, and Move Down

  Operations used to manage the existing connections.

• Test Connection

  Tests the selected MySQL connection and reports the connection status. It also reports which encryption protocol and cipher MySQL Workbench uses to enable SSL.

  For testing remote connections, you might also use ping to check the host name, or telnet to also check the port. If these fail, then also check the firewall settings on each host, and also that MySQL server is running on the remote host.

Notes on MySQL Connection Manager

Note

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.
