At the top right of this figure is the label "WebLogic Server." Below that label is a pentagon labeled "Multi Data Source." Inside the Multi Data Source are two rectangles side-by-side, each labeled "Data Source."

Below the Multi Data Source for the WebLogic Server on the left is a computer labeled "RAC Node 1," and below the Multi Data Source for the WebLogic Server on the right is a computer labeled "RAC Node 2." RAC Node 1 and RAC Node 2 are joined by a line labeled "InterConnect."

In the Multi Data Source on the left, an arrow begins at the Data Source on the left and points to RAC Node 1, and an arrow begins at the Data Source on the right and points to RAC Node 2.

In the Multi Data Source on the right, an arrow begins at the Data Source on the left and points to RAC Node 1, and an arrow begins at the Data Source on the right and points to RAC Node 2.

Both RAC Node 1 and RAC Node 2 have a line that begins at the Node and points to a storage volume below the RAC Nodes that is labeled "Shared Storage."
