Configuring general mid tier settings

The number of minutes after which the current session will expire. When the system has exceeded this amount without any activity, you must log on again. A session timeout clock in the status bar appears in the web browser of each user session. The clock shows how much time is left before an HTTP session will time out. If a user performs any activity in an application on the Mid Tier and that activity results in a server-side call (such as a backchannel call or opening a new form), the clock timer starts over. If a user action is only on the client side (such as data entry), the clock does not reset. The session timeout clock has an update granularity of 1 minute. At each 60-second interval, the Oracle JavaScript controlling the session timeout clock is executed to update the clock with the amount of time available before the HTTP session times out. For example, if 1 minute and 32 seconds remains, the display time will read 2 minutes.

If the form is viewed in a Firefox browser and the form includes a view, Flashboards , or data visualization field, the session timeout clock might not appear.

If a user is entering data in a form, that data might be lost if the session times out before the user submits the data. To prevent possible data loss after a timeout, the user should leave the data visible in the form and use the same login ID to open a new instance of the browser window. In the new browser, the user should then navigate to the form, copy the data, and paste it into the new form. If users experience frequent timeouts, increase the session timeout interval. The default value is 90 minutes; there is no upper or lower limit. The entry in the Session Timeout in Minutes field of the AR System User Preference form (Web tab) will override this setting for a specific user.

The number of seconds before Mid Tier releases a AR System user license associated with a user if that user does not log out of Mid Tier properly. To log out properly, the user must close the last browser window associated with the current HTTP session or navigate away from Mid Tier . The default delay is 60 seconds. Mid Tier initiates a delay timer when the user closes the last browser window associated with the established HTTP session. When the delay timer expires, the user's license is released, and the HTTP session terminated. If the user navigates back to the mid-tier URL before the delay time expires, the delay timer is cancelled, and the current HTTP session is resumed.

The name of the AR System server designated as a preference server. You can specify more than one server if you need multiple preference servers to support different departments or business units. If you enter more than one preference server, the system searches the list until it finds the first preference server that matches the user name and uses that server as the preference server. To add or update preference servers, enter the name of each server that you want to designate as a preference server. If you are adding more than one server, separate each name with a comma (for example, mars, jupiter, saturn). A fully qualified server name is not valid in this field.

All servers designed as preference servers must be included in the AR System server list on the AR Server Settings page. For more information, see Configuring AR System servers that the mid tier uses..

The name of the AR System server designated as a data visualization module server. You can specify more than one server if you need to copy the modules to another server as a backup in case the first module server goes down. To add or update module servers, enter the name of each server that you want to designate as a module server. If you are adding more than one server, separate each name with a comma (for example, mars, jupiter, saturn). A fully qualified server name is not valid in this field.

All servers designed as module servers must be included in the AR System server list on the AR Server Settings page.

The server that contains the home page that you want to open in the browser when the user logs on. The home page URL is: http://<midTierServer>/<contextPath>/home. The home page server must already in the list of AR System server s on the AR Server Settings page. For information, see Configuring AR System servers that the mid tier uses. Mid Tier searches this server for the designated or default home page. This server is used globally if you have not selected a home page server in the AR System User Preference form. A home page server specified in the AR System User Preferences form takes precedence over the server set here. The form used for the home page has the following precedence on a specific server:

1. A form designated in the AR System User Preference form.
2. A default home page designated in the AR System Administration: Server Information form.
3. The default home page installed with AR System.

For more information, see Home page preferences.

The server that Mid Tier uses to authenticate the user. If an authentication server is specified, Mid Tier authenticates with the specified server only. The server specified here must already be in the list of AR System server s on the AR Server Settings page. For more information, see Configuring AR System servers that the mid tier uses. If an authentication server is not specified, Mid Tier behaves as follows:

1. Logs the user in with the preference server, if one is specified.
2. If there is no preference server, logs the user in to the first server listed in the AR Server list.
3. If that login is not successful, logs the user in to the next server on the list. (A guest login is considered a successful login.)

Indicates whether you want to enable the AR System Object List that displays all the forms and applications that Mid Tier can access. If the check box is:

• Selected—The Object List is displayed automatically when the system cannot determine the specific form to load because an incomplete URL is entered into the browser or an application does not define a primary form.
• Cleared (default)—The AR System Object List is not enabled and is not displayed when the system cannot determine which form to load.

For more information, see Setting up the Object List.

Enable Mid Tier Performance MBean (requires restart)

Indicates whether Page Response Time is measured and displayed on Mid Tier application pages in the browser. If the check box is:

• Selected—Page Response Time Monitor is enabled on all pages.
• Cleared (default)—Page Response Time Indicator is not enabled and is not visible when a page is displayed.
