In your OracleAS Identity Management cluster environment:
1. You are using the Oracle Real Application Clusters (RAC) to ensure high availability of
OracleAS Metadata Repository.
2. There are two instances of the database that are running on two different nodes in RAC
On Friday morning, OID users in your OracleAS environment complain that their sessions are
disconnected and they are not able to connect again.
While investigating the reason, you observe that one of the nodes in the RAC is shut down for
regular maintenance activities and the user sessions did not fail over to the second node in the
RAC, thus causing the problem with the user sessions.
Which option would you consider to avoid this problem in future?
A.
creating an interconnect between the RAC nodes to propagate the client requests
B.
configuring load balancer in the tnsnames.ora file to distribute the connections between the
RAC nodes
C.
configuring the Connect-Time Failover (CTF) in the listener.ora file to enable connection
failover between the RAC nodes
D.
configuring Transparent Application Failover (TAF) in the tnsnames.ora file to enable request
failover between the RAC nodes
