The port can be found in the following code:

LISTENER = (DESCRIPTION_LIST =

(DESCRIPTION = (ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521)) (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))

)

)

)

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).
