This section discusses a few default iView properties that are common to most iView types, and refers you to topics which discuss them in more detail. They are brought to your attention since they have an overall effect on portal performance and stability.

Isolation Method

The isolation method of an iView determines how an iView is technically integrated into a portal page at run time.

For more information, see Isolation Method of iViews .

iView Caching

iViews have several cache-related properties, which determine whether an iView retrieves data from its data source or from a cached store. Retrieving existing data from a cached store decreases the fetch time of an iView, thus improving the performance of a portal page when displayed at run time. The frequency an iView needs to update its cached store depends on the dynamics of each data source; therefore it is possible to specify the cache properties per iView. For information on these properties, see Navigation Caching .

In addition, the portal has a global setting that also affects client-side browser caching. For more information, see Configuring Application Caching .
