Clearing the portal cache

For better portal performance, pictures and translated labels are cached in the web application on the IIS server. The first time a label or picture is retrieved, it is added to the cache so that subsequent access is faster.

Cached objects remain on the server indefinitely. If you change a picture or update a label, you must force a reload of the cache so that the change takes effect immediately.

Note: If the portal web application is restarted, the cache is cleared automatically. A low memory condition on the server can also cause objects to be cleared from the cache.

To clear the cache manually, follow these steps:

Select the data source for which to clear cache and click Clear Data Source Cache.
