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 is
listening on TNS port LP2, then it is possible to automatically discover SID2, provided that TNS
port LP2 is part of the default port list in the Application Setup page.
To discover Oracle RAC:
1. Install the CIM extension on each node in the cluster.
2. If the cluster is not automatically discovered by the management server, create the cluster using
Cluster Manager. For more information about Cluster Manager, see ”Host and Application
Clustering” on page 129.
3. Create the APPIQ_USER account on any one node in the cluster. See ”Step A — Create the
APPIQ_USER Account for Oracle” on page 90.
4. Discover the host for the first node in HP SIM. See ”Step A — Set Up Discovery for Hosts” on
page 85.
5. Discover the first Oracle node as follows:
a. Select Options > Protocol Settings > Storage Essentials > System Application Discovery
Settings.
To select a target, you must have at least one element designated as a server,
workstation or desktop. If you see the message “No Targets Currently Selected,”
change your element from unknown to either a server, workstation or desktop.
