问题
It is not related to whatever version it is, just working to find out how to change (of course increase) session timeout value of Squirrel Sql Client. Because I really get bored of getting kind of exception "Last packet sent to the server was .. ago"
Any help would be appreciated.
回答1:
You can keep the connection alive by doing the following:
On Aliases->Modify the Selected Alias (pencil icon)-> Properties-> Connection (tab)
Check Enable Keep-Alive
and enter a simple query, in PostgreSQL I use SELECT 1;, in Oracle should be something like SELECT 1 FROM dual;

Solution for MySQL:
- Right-click a connection alias and select "Modify alias"
- Click "Properties" and select the "Driver properties" tab
- Set the property "autoReconnect" to "TRUE"

If you're connecting to an Apache Derby db, use the following keep-alive test SQL:
VALUES 1

I faced the same problem with my local development machine. Since using the driver property "autoReconnect" is discouraged by SQuirreL, I looked for another alternative which fixes the root cause.
I have access to the /etc/mysql/my.cnf directory on my Linux VM, so I could tweak the variable wait_timeout. Previously, it was set to 600 (600 / 60 seconds per minute = 10 minutes). I then set it to 28800 which is the MariaDB default.
After restarting the MySQL server using service mysql restart, everything worked like a charm!

Locate the the prefs.xml in the installation directory and change the default loginTimeout value to your desired value and you are done.
