Clearing the Portal Runtime Cache 

Use

At runtime, you can view the portal objects that are in the cache in order to monitor runtime objects.

By doing so, you can detect which ones need fine-tuning for improved response time and performance. The cache mechanism uses the memory (RAM) and the database for the portal.

Inconsistencies can occur between the cached objects in the memory and the cached objects in the database. You can detect this condition only by viewing the cached contents.

You resolve these inconsistencies by deleting the portal runtime cache in the database. This operation clears both the cached objects in the memory and the database.

Procedure

       2.      At the prompt, logon to the portal.

Make sure that you receive a notification about clearing the cached content.
