Securing Your System
Disabling rsh

requirement for the root user. Please ensure that
ssh
is disabled for all the nodes of
the RAC. You can disable
ssh
by removing all files in the following directory:

NOTE: It is highly recommend that all the nodes of the RAC have security configured
according to your security policy.

system. Complete the following steps to create the
oracle
password:
