DNS lookup. Such fields also have a red box around them. The Lookup IP also
highlights the field in red if the user input differs from what is found in DNS.
3.2.12 Define Clusters
More than one cluster can be defined for Oracle Exadata Rack environments. Larger
environments support multiple clusters. Each cluster requires a minimum of two
physical database servers, and three Exadata Cells.
If one cluster is used, then click All to move all components to the cluster. If more then
one cluster is used, then enter the number of clusters. For each cluster, select its
subtab, then select the components for the cluster, and then click Add.
3.2.13 Define Clusters Details
The following table lists the cluster fields. Most fields are filled in based on earlier
configuration pages.

OS Field
Description
Cluster name
Assigns the cluster name.
Note: The name can contain alphanumeric
characters, periods (.), and hyphens (-). The
name must start with an alphanumeric
character.
This field cannot be empty.
Prefix
Assigns the prefix for the cluster.
DNS
Sets the DNS IP Address.
Note: At least one IP address must be
entered.
NTP

Note: At least one IP address must be

Domain Name
Sets the cluster domain name.
Region

Timezone

Role Separated
Allows the responsibilities and privileges to be
separated by role.
Note: Providing system privileges for the
storage tier using the SYSASM privilege
instead of the SYSDBA privilege provides a
clear division of responsibility between Oracle
ASM administration and database
administration.
When used with Oracle ASM and database-
scoped security, role separation helps to
prevent different databases using the same
storage from accidentally overwriting each
other's files.
