Question 73/82
You plan to remove a node called RACNODE4 from a four-node cluster.
The cluster is running Oracle Grid Infrastructure 11g Release 2 and there is also a database home with cluster databases running Oracle Database version 11g Release 1. This older home supports different applications that have not been certified to run on the latest release.
The cluster databases for Oracle Database 11g Release 1 each had four Instances at one time, but currently only the first two nodes, RACNODE1 and RACNODE2, are running instances of those databases.
Which two additional steps are required when deleting a node from a cluster in this situation?

Correct Answer: C,E
Explanation/Reference:
Explanation:
Deleting a Cluster Node on Linux and UNIX Systems
1. Ensure that Grid_home correctly specifies the full directory path for the Oracle Clusterware home on each node, where Grid_home is the location of the installed Oracle Clusterware software.
2. Run the following command as either root or the user that installed Oracle Clusterware to determine whether the node you want to delete is active and whether it is pinned:
$ olsnodes -s -t
If the node is pinned, then run the crsctl unpin css command. Otherwise, proceed to the next step.
