MySQL Workbench: How to keep the connection alive

Solution 1:

From the now unavailable internet archive:

Go to Edit -> Preferences -> SQL Editor and set to a higher value this parameter: DBMS connection read time out (in seconds). For instance: 86400.

Close and reopen MySQL Workbench. Kill your previously query that probably is running and run the query again.

Solution 2:

If you are using a "Standard TCP/IP over SSH" type of connection, under "Preferences"->"Others" there is "SSH KeepAlive" field. It took me quite a while to find it :(

Solution 3:

In 5.2.47 (at least on mac), go the location of the preferences is: MySQLWorkbench->Preferences->SQL Editor

Then you'll see both:

The latter is where you'll want to up the limit from 600 to something a bit more.

Solution 4:

In my case after trying to set the SSH timeout on the command line and in the local server settings. @Ljubitel solution solved the issue form me.

One point to note is that in Workbench 6.2 the setting is now under advanced
