Discovering Oracle Real Application Clusters (RAC)
Since Oracle RAC is an active-active application cluster, one RAC instance can provide information
for the whole RAC. Regardless of the instance through which the database is accessed, the same
sets of tables are accessed. This includes the data dictionary tables that are used to understand the
logical and physical storage organization of the Oracle RAC application.
Discovering single instance Oracle failover clusters
It is possible to operate a non-RAC oracle instance as a clustered active/passive application. In this
case, the single oracle instance is configured as a cluster resource. The clustering software
(Example: VCS, Service Guard) is then responsible for monitoring the oracle instance and failing it
over to other operating nodes in case of a node failure.
In case of a single instance failover cluster, the oracle instance by itself will not be able to indicate
that it is operating in clustered mode. Follow these steps to set up discovery of a single instance
Oracle failover cluster:
Discovery of single instance Oracle failover cluster
The conditions to be satisfied for discovering single instance Oracle failover clusters are as follows:
• All the hosts in the cluster configured to handle single instance Oracle failover should be
discovered in the management server.
• The management server must be able to contact the hosts running the single instance Oracle
failover instance using the short host name. The management server can be configured to access
the hosts running a single instance Oracle failover instance using the short name in the following
ways:
• On the management server, add entries for each host configured for single instance Oracle
failover instance in /etc/hosts (on UNIX platforms) or
%WINDIR%\system32\drivers\etc\hosts
(on Windows).
• Add the domain of the host in the domain search list of the management server under the
search option of /etc/resolv.conf (on UNIX platforms) or Append these DNS suffixes
(in order) on the Advanced TCP/IP Settings > DNS tab (on Windows).
