Select the nodes in the existing cluster that you want to upgrade to this release.
You must have SSH configured on all nodes for the installation owner user on all nodes that you plan to upgrade.
Click the SSH Connectivity button to configure SSH.
Installation requires SSH connectivity to be configured between nodes in the cluster, so that the Installer can open secure remote shell sessions as the installation owner account on each cluster member. If you have completed the required task of setting up identical groups, users and passwords on all nodes for the installation owner account, then the Installer can configure passwordless SSH access.
The installation owner (the user account running the installation) is listed by default as the Operating System Username. Provide the password for that user in the Operating System Password field. You can also set up SSH for other user accounts if they are configured identically on all prospective cluster members.
Click Test if you think SSH connectivity has been set up, so that you can confirm that it is operating.
Click Setup to start the SSH configuration process.
If you are using a shared location as the home for the installation owner account, then click User home is shared by the selected nodes.
If you have existing SSH keys set up in the installation owner account, and you want to enable the existing SSH keys by reloading them into memory, instead of generating new keys, then click Reuse private and public keys existing in the user home.
If you have locked operating system accounts, then you must create the SSH configuration manually. Refer to operating system documentation, or to the Oracle software installation guide for manual SSH configuration instructions.
Oracle Automatic Storage Management (Oracle ASM) is included with the binaries installed with Oracle Grid Infrastructure installations. If you have an existing version of Oracle ASM on your cluster, then by default Upgrade Cluster Automatic storage Management (ASM) is selected, and all nodes are selected for upgrade. You can deselect the upgrade ASM option, or remove nodes from the upgrade list.
Only one release of Oracle ASM can run on servers. If you want Oracle ASM to be upgraded, then you must select all nodes of the cluster to upgrade Oracle ASM. You can select a subset of the nodes for upgrade, but if you do this, then you cannot upgrade Oracle ASM. Only Oracle Clusterware is then upgraded on the subset of nodes that you select. If you select all nodes for upgrade, but uncheck Upgrade Cluster Automatic storage Management (ASM), then only Oracle Clusterware is upgraded.
