When this happens, Toad must activate one of the remaining open windows. At that point, the active connection must also change to the connection of the newly activated window. Otherwise you'd get into a state where active window's connection active connection. That is a weird situation that we try to avoid.
You can customize your Toad workspace by re-arranging windows and panes. For docked panes selected from the View menu, Toad remembers the configuration of your last open session and displays it when you re-launch the application.
The Editor button makes opening additional Editor windows possible. This version of Toad enables you to open additional tabs in the Editor window. Simply right-click the tab just above the selected statement and select SQL or PL/SQL tab type. This opens another Editor window using the same database connection. Use the Editor button in the top-left row of buttons to open another Editor window, perhaps using a different connect string.
This is the easiest way. More involved is adding the name of the database to the TNSNames in your oracle client.Another good check is to log onto the server where the database is and start a DOS command line window. Enter lsnrctl status . This will give you the database name and port and if the listener is ready to receive connections.
Open a Windows explorer window, and navigate to the folder that is defined as the variable value for the TNS_ADMIN environment variable. If you created the TNS_ADMIN environment variable using these instructions, the folder path will be C:\oracle. If the folder does not exist, create it.
