Note: WebSphere Portal
v5.1 servers cache the contents of pages. When you run a portal project on
a remote server, you may not see changes to the contents of pages for up to
10 minutes, which is the default lifetime of the cache. To change the cache
lifetime, change the value of the cacheinstance.com.ibm.wps.model.content.impl.ResourceCache.lifetime parameter
in the Portal_installation_directory/shared/app/config/services/CacheManagerService.properties file
on the remote portal server. The value is the number of seconds that the cache
is kept. The values 0 or -1 mean there is
no timeout. If you change the structure of labels and pages and the changes
do not appear in your Web browser, explicitly log out of WebSphere Portal
using the Web browser and log back in. After the login, the changes will be
shown. Note that closing the Web browser window may not work. The log out
and log in steps need to be performed every time an updated portal project
is published.
