Automatic refresh
ZIETrans provides both client pull and server push functions for updating the client browser with asynchronous outbound data. See Automatic Disconnect and Refresh (Web-only) for details about these functions.
Use of these functions is another way to tune the ZIETrans screen-settling
process. Whether you use these functions can be based on:
- How your applications work with just tuning the screen-settling settings, if necessary.
- Whether enabling Contention Resolution for TN3270E hosts is an option.
- Whether portal, firewall, or other considerations would limit their use in your deployment.
Using either of these functions can enhance performance by enabling screen-settling times to be reduced, since missed updates can be refreshed on the client when they are received at the application server. Several default screen-settling settings are changed when the server push (applet) function is configured and running on a client. See Table 2 and Table 1 for more information about these settings.
