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.
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.
