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.
Discovery of Oracle RAC Instances Using One Instance
Because one RAC instance can provide information for the whole RAC, it is possible to identify and
discover all the instances in the Oracle RAC cluster from any one of its instances. This means that
the you can enter the application setup information for one instance of the Oracle RAC, and the
management server will automatically discover the other instances, subject to certain conditions.
The conditions to be satisfied for discovering all the instances of Oracle RAC using application
setup information from one of its instances are as follows:
• Only the Oracle RAC instances running on hosts already discovered and identified as part of
the same cluster will be discovered as part of the Oracle RAC on the management server.
• The management server is able to contact the hosts running Oracle RAC instances using the
short host name. The management server can be configured to access the hosts running Oracle
RAC instances using the short name in the following ways:
• On the management server, add entries for each host running an Oracle RAC 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).
• The listener is configured on the same IP address that is used to discover the host. For example,
on the Application Setup page, the management IP address for the application should be the
same as the host IP address.
• Typically, all the instances of Oracle RAC will be listening on the same TNS port number. If this
is not the case, the port numbers for the other instances should be specified in the default port
list in the Application Setup page. For example, if SID1 is listening on TNS port LP1, and SID2
