Database Reference
In-Depth Information
When the inactive nodes become accessible after a forced upgrade, you can join them to the cluster to either
upgrade or delete them from the cluster. Execute the following examples on the first node of the cluster to join the
node that was not accessible during the course of the upgrade:
$/u01/app/12.1.0/grid/crs/install/rootcrs.pl -join -existingNode rac1 upgrade_node rac2
In the preceding example, existingNode indicates the node on which the upgrade was successful, and upgrade_node
is the node which was not reachable during the course of upgrade and wants to join the node in the cluster after a
forced upgrade.
Installing Oracle 12c RDBMS Software
You will have to install the new Oracle 12c RDBMS binaries into a new RDBMS location right after your Clusterware
upgrade to ally with the complete Clusterware environment upgrade procedure.
As stated earlier on, from 11gR2 onward, all upgrades are now out-of-place upgrades; you will have to create
a new location in the context for the Oracle 12c binaries and install the software. This procedure will not have any
impact on the active databases on the respective nodes unless you select the “Install database software only” option.
In other words, we advise you not to select the “Upgrade an existing database option” on the Select Installation Option
screen, as shown in Figure 13-12 .
