If you manually disconnect from an Essbase Server, you can reconnect. Essbase must be started before you can connect to it.
In Administration Services, connections to individual Essbase Servers are handled by the middle-tier Essbase Administration Server. You need not provide a user name and password to establish individual Essbase Server connections. For more information about how Essbase Server connections and ports are established and released, see About Essbase Connections and Ports.
For information about adding Essbase Servers to Enterprise View, see Adding Essbase Servers to Enterprise View.
You can connect to different releases of Essbase simultaneously from the Administration Services Console. See the Oracle Hyperion Enterprise Performance Management System Certification Matrix (http://www.oracle.com/technology/products/bi/hyperion-supported-platforms.html) for release compatibility information.
To connect to an Essbase Server manually:
From Enterprise View or a custom view, find an Essbase Server.
Perform an action:
Right-click the Essbase Server node, and select Connect.
Expand the Essbase Server node.
Administration Services repopulates Enterprise View.
