Some more useful information

You can configure several global properties to control the portal cache. These properties are in the file prtDefault.properties, located in the portal installation folder

/usr/sap/<SID>/<instance>/j2ee/.../cluster/server/services/servlet_jsp/work/jspTemp/irj/root/ WEB-INF/portal/system/properties.

caching.maxsize=5000

The default maximum size of the cache in KB before it is removed.

enable.http.conditional.request=true

Specifies whether the cache supports client-side (browser) content caching.

caching.cluster.notification=false

Enables the cluster notification.

prt.caching.persistency=true

Specifies whether to keep cached content in the database for all applications using the cache layer.

prt.pc.caching.persistency=true

Specifies whether to also keep cached portal components in the database. This is currently disabled.

Other cache properties can be configured via the portal.runtime service configuration.

To set the cache for the runtime application:

• Open the portal and log on with your administration user.

• From the Top-Level Navigation, choose System Administration &#8594; System Configuration.

• From the Detailed Navigation, choose Service Configuration.

• In the Content Catalog, expand Applications &#8594; portal.runtime &#8594; Settings &#8594; config.

• Right-click config and choose Edit to open the Service Configuration Editor.

There are several properties for this application, including the following cache settings:

caching.off=false

Specifies whether PRT caching is enabled

caching.persistency.clean.period=120

Specifies the period for cleaning the cache, in database units

Hi Piyush,

Your posts have been very useful.

I am facing a scenario in our implementation.

We have set up a Navigation iView to manage the repositories and its documents. This will be the main iview that all users would use.

However, the links in the Navigation iView such Folder links , menu's never respond in one click. Sometimes, there is no response even if we click 10 times.

However, the same iView when accessed from outside our network, works fine.

Do i have make any specific settings in the Portal / Browswer to get rid of this problem ?

Kindly help.

The portal has a caching service that supports content caching for a page/iView on the portal server. In addition, it can implement content caching on the client machine using the browser’s caching capabilities. Configure caching properties for pages/iViews at design time. Depending on your configuration, the portal can cache content as follows:

• On the portal’s server

The generated content or output of an iView can be stored in the server’s cache using the portal caching capabilities. Doing so saves time and the resources required to regenerate the content when the iView is called on subsequent requests.

• On the client’s browser cache

Using the portal caching capabilities on the client minimizes network traffic and displays content faster, as the content is taken from the browser’s cache. The browser uses an HTTP conditional request to check whether content in its cache is still valid. If the content in the cache has expired, it is discarded and replaced with content retrieved from the server.

You can activate the following cache settings for pages/iViews:

CacheLevel

CacheValidityPeriod

AllowClientSideCaching etc

lot more...
