Session Management

STA provides various options for managing your login sessions and modifying the STA user interface display. Because these modifications are made on a username basis, different users can modify the settings to their own needs. The following options are provided:

Screen Interval Options

You can modify both the screen refresh and automatic timeout intervals for your username.

Screen Refresh Interval

The STA screen display is refreshed automatically to display new data that may be available. The default refresh rate is every 480 seconds (8 minutes). You can optionally change the refresh rate for your username. See “Modify the Screen Refresh Interval” for details.

Automatic Timeout Interval

The default session timeout is 30 minutes. You can optionally change the timeout period for your username to any period from 10 minutes to 60 days. See “Modify the Login Session Timeout Period” for details.

Note – Increasing the session timeout is likely to increase STA server memory utilization, with possible impact on STA performance. See “Logging Out” for additional information.

If your login session is idle for the defined amount of time, your session will be ended automatically. Two minutes prior to the expiration time, the following dialog box appears. Click OK within the two-minute period to keep your session active.

If you do not click OK within the two-minute period, your session is ended, and the following dialog box appears.

When you click OK, you are re-directed to the Login screen so you can log in again.

Removed Drives and Media Display Options

By default, removed drives and media are not included on their respective Overview and Analysis screens. However, you can selectively turn on the display of either removed drives, removed media, or both. Your selections take effect immediately, so depending on your needs, you can selectively show or hide removed drives and media throughout your login session. See “Modify Removed Drives and Media Display Settings” for instructions on how to change the settings.

TABLE 2‑1 summarizes the effects of selecting or deselecting each option. See “Understanding STA Analytics” in the STA Data Reference Guide for a more detailed discussion of the effects.
