UMP is configured by default for session timeout is 5 mins.
The default timeout in UMP can be modified as below.
For this you will have to modify settings in two files. First file is within the following path, just make sure to modify according to your environment:
C:\Program Files (x86)\Nimsoft\probes\service\wasp\webapps\ROOT\WEB-INF\classes\portal-ext.properties
The section below is the one you want to modify and, for this you will have to first deactivate the wasp probe, due to permissions, it might be easier for you to copy the file to your desktop, make the changes you want and copy it back to overwrite the existing file in the directory.
# Time out after five minutes, but automatically request an extension after one
# minute as long as the user is currently browsing to a portal page. The
# timeout is really configured in ../web.xml.
