You want to install Grid Infrastructure for a cluster and the Oracle Database software (with the
RAC option). Do you need SSH user equivalency?
A.
Yes, to ensure security during the installation.
B.
Yes, to set up administrative privileges for the DBA.
C.
Yes, to allow the use of SSH and SCP without being prompted for a pass phrase.
D.
No, you don’t need SSH user equivalency.
Explanation:
During the installation of Oracle RAC, OUI needs to copy files to and execute
programs on the other nodes in the cluster. In order to allow OUI to do that, you must configure
SSH to allow user equivalence. Establishing user equivalence with SSH provides a secure means
of copying files and executing programs on other nodes in the cluster without requiring password
prompts.
