Configuration

The portlet is intended to operate in 2 different modes:

• In portal mode

In this state the portlet offers the entire set of possible operations on resources but it allow access to only the scope related to user's portal session.

• Stand alone mode

In this state the portlet offers the possibility to access all available scopes, but it's not possible to make any changes to resources.

The configuration is done by editing the config file config/config.properties and setting the values "true|false" to the mode labels. Please note that this file is loaded by the application at start-up time, so you need to restart it after editing the file, to let the modifications affect the portlet's behaviour.

Scopes

To let the portlet manage new INFRASTRUCTURES and VO scopes , you should edit the xml/scopedata.xml file by putting new scopes description as described in the Configuring Infrastructure Viewer section of the Monitor System documentation.
