Universal Installer displays this page when you specify an existing Oracle home within a Real Application Clusters environment as the installation destination.
The list box on this page displays the nodes in the current cluster selected during the original installation into this Oracle home. Note that this list may not represent all nodes.
Selected nodes are tested for the following conditions:
Network reachability: Tests whether the remote cluster nodes are up and running.
Network configuration: Tests whether the remote cluster nodes are properly network configured.
Inventory setup: Tests whether the inventory is set up on the remote nodes. If not set up, on Unix, OUI prompts the user to run root scripts on the remote nodes to set up inventory. On Windows, OUI sets up the inventory location in the Windows registry.
Inventory permission: Tests whether the central inventory location is writable by the user.
If all selected nodes are available, the installation process continues to the next step. If a node (or nodes) is not available, the page is re-displayed with a Status column indicating the node's status: "Available," "Node not reachable," "Network not configured," etc. You must fix the problem or choose another set of nodes in order to proceed.
If any of the remote nodes is unreachable, check if those nodes are up and running and if they are properly network configured. If either the inventory or the Oracle home is not writable, check for the appropriate permissions on the remote nodes for these directories.
Existing inventories of selected nodes are locked during installation to prevent multiple, concurrent sessions (unlocked when installation session completes).
For more information about using OUI to install in a cluster environment, see the Oracle Universal Installer Concepts Guide.
