How do I keep my database connection alive?
Databases can be configured to terminate sessions that have been idle for some time, and networks often does the same with TCP/IP connection. The Connection Keep-Alive feature helps preventing connections to be closed due to time-outs of this kind by periodically executing a simple SELECT statement.
Should I keep database connection open?
While the specific details matter in general there is nothing wrong with keeping connections open for long durations. If your application is connection pooling – the connection slots in the pool typically remain connected until they are needed.
How are database and server connected?
Generally, you connect through the Database Servers node if you must perform administrative tasks that affect the database server or multiple geodatabases on the database server. If you only need to access the data in one geodatabase on the database server, connect under the Database Connections node.

How long does a database server stay active?
The default value is 2 hours. Therefore, the database server job can stay active for 2 to 4 hours. Adjust the idle timeout for the firewall or router. Adjust any connection pools idle timeout value to a value lower than the idle timeout of the network. Lower the TCP keep-alive. The keep-alive frame might reset the inactivity timer.
How to keep track of all connections in SQL Server?
You can then run that trace in the background and save it to a file which can later be imported into a SQL Server table.
Is it better to keep database connection open all the time?
Depends on what are your needs. Creating a connection takes some time, so if you need to access database frequently it’s better to keep the connection open. Also it’s better to create a pool, so that many users can access database simultaneously (if it’s needed).
What to do when your database connection drops?
Adjust the idle timeout for the firewall or router. Adjust any connection pools idle timeout value to a value lower than the idle timeout of the network. Lower the TCP keep-alive. The keep-alive frame might reset the inactivity timer. Some network components appear to ignore keepalives.
