Server Output

Capture output from the Oracle server and display it in the Output Window.

 

Tips For Use

Toggle on/off
  • Toggle on/off capturing server output from the Session Menu.
  • Click Session | Server Output to toggle On/Off Server output.

Output Window
  • When toggled ON the Output Window opens if it is not already open.
  • Closing the Output Window does not stop the capturing of Server Output.
  • The Output Window reopens automatically if you execute a stored program in a session capturing server output.
  • The default size of the run time buffer is 32k bytes.

Oracle Sessions
  • Output is captured for the current Oracle session.
  • Server Output is captured individually for each session. Capturing it in one session does not automatically capture it in other concurrent sessions.

Server Side Installation Wizard

The wizard requires connection as a DBA user so that the SQLNAV user can be created, as well as a number of roles. The wizard permits you to specify a password of your choice for this user. Note that the option "Base SQLNAV Repository" must be selected on at least one occasion to allow the other support features to be installed. All objects installed by the wizard are installed into the SQLNAV schema.
