This figure illustrates a clustered architecture in which both the applications and the Oracle Database are managed via Oracle Clusterware for high availability. Starting at the top of the figure, two servers are in a box (outlined with a dotted line) that is labeled "Application/Web Servers. To the left of the servers there is another label: "Applications and Web Servers Managed by the Oracle Clusterware API." Both of the servers are connected to another box labelled "Oracle Net Services Client Access" and this box is shows separate connections to two nodes:

• Node 1 is in a yellow box and is also connected by a line to the "Pool of Storage" below, to indicate that the instance is actively servicing database requests from the applications.

• Node 2 is not in a box and is outlined with a dotted line to indicate that this node is in standby mode. The node is not actively servicing application requests for this database.

To the left of the Nodes is another label: "Single-Instance Oracle Database Made Highly Available with Oracle Clusterware."

At the bottom of the graphic, directly below the Nodes there is a picture of a single a row of disks with the label "Pool of Storage." The six disks in the pool of storage are contained in a dotted-line box. Within this dotted-line box, the two left most disks are labeled as "Database Area" and the four disks to right are labeled as "Flash Recovery Area."
