The illustration contains a vertical flowchart representing the sequence of events and the available extension points in a multitenant workflow. The topmost box in the flowchart is Start Rollout. The next boxes represent the events that occur inside the rollout once it has started. The next box is Check Prerequisites which points to an extension point called ep_OnlineBeforeUpdate that is available to add any custom prerequisite check. The next box in the sequence is For Every Node which signifies the operations that take place within every node. Next in sequence is the extension point,ep_EachNode that allows for adding any custom operation to be performed at each node. The next boxes, in the descending order, are Update Cluster Settings, and Shutdown All Targeted Resource Groups on the Node. This points to another available extension point, ep_OfflineBeforeUpdate that allows for any custom operations to be performed before the Oracle home/Java home/application update starts. Next, in sequence is Start the Resource Groups and Update Applications. This points to the extension point ep_OnlineAfterUpdate.
