Clearing and Synchronizing the Federated Portal Cache 

Applicable to: remote role assignment, remote delta link

Use

This topic describes how to manually clear or synchronize the federated portal cache, if needed. Clearing the cache refers to roles consumed through remote role assignment, while synchronizing the cache refers to remote delta links.

Prerequisites

You have access to the federated portal administration tools in the standard System Admin role on your portal.

Procedure

Clearing the 'Remote Role Assignment' Cache and Scenario-Specific 'Remote Delta Link' Cache

The Cache Lifetime setting in the Cache Management iView and the properties in the FederatedPortalCache service determine the frequency at which the cache of remotely assigned roles is cleared automatically (for more information, refer to Configuring the Federated Portal Cache). There are may be times when you want to manually clear the cached content of roles that you have consumed through remote role assignment before their cache lifetime expectancy has been reached. For example, if you know that a producer has updated content you are consuming, you can clear the cache to ensure that all data changes are immediately updated on your consumer and that your users are working with the most up-to-date content.

Note that the Cache Lifetime setting and the properties in the FederatedPortalCache service also have an effect on specific remote delta link use cases. For example, if a content administrator on the consumer portal has made a change to an application property in a SAP transaction iView of type remote delta link, the administrator should clear the cache manually before the cache lifetime expectancy has been reached, so that business users run the iView with the most up-to-date values. The procedure described below also applies to the clearing of cached data for the aforementioned remote delta link instances.

■       After you clear the cache, portal users may notice an initial increase in the time it takes for remotely assigned role content to be retrieved from the producer portal. As the cache is rebuilt on the consumer over time, runtime performance improves.

■       Users must restart any live portal sessions to receive the latest updates after clearing the cache.

To manually clear the remote role assignment cache and limited remote delta link use cases:

...

       1.      In the consumer portal, navigate to System Administration → Federated Portal → Myself as Content Consumer → Cache Management.

       2.      In Content consumed by Remote Role Assignment, click Clear.

Remote content displayed in the NetWeaver Content Producers folder in the Portal Catalog enables you to create remote delta link content on the consumer portal. If you are having problems when viewing content in the NetWeaver Content Producers folder, such as content not updating itself or the Portal Catalog being empty after refreshing, you can use the Clear feature to solve the problem.

Synchronizing the Cache for 'Remote Delta Link' Content

The cache settings in the OriginalContentSynConsumerService service define the frequency at which remote delta link content on the producer is updated with modifications made to their source objects on a producer portal (for more information, refer to Configuring the Federated Portal Cache).

Apart from changing the default synchronization interval, a system administrator on the consumer can at any time manually synchronize the remote delta link content on the consumer with their corresponding source objects on the producer.

An administrator on the producer portal cannot initiate a content update with its registered consumer portals. It can only be initiated from the consumer portal.

■       Synchronization can be a very time consuming process, especially if you have consumed large amounts of remote delta link content.

■       After synchronizing the cache, portal users must restart any live portal sessions to receive the latest updates.

To manually synchronize the remote delta link content cache:

...

       1.      In the consumer portal, navigate to System Administration → Federated Portal → Myself as Content Consumer → Cache Management.

       2.      In Content consumed by Remote Delta Links, do the following:

...

                            a.      Choose what level of content you want to synchronize by selecting either Synchronize only modified content or Synchronize all content.

Synchronizing only modified content is recommended; if you have consumed large amounts of content, synchronizing all content can take a long time to complete. 

                            b.      Choose with which producers you want to synchronize content by selecting either Synchronize with all producers or Synchronize with a selected producer and then choosing the alias of the producer.

                            c.      Click Synchronize.
