Preparing for Exadata - Oracle Exadata Recipes: A Problem-Solution Approach - page 150

■ the infiniBand cable lengths do not just apply to interconnected exadata racks. if you plan on connecting any
of oracle's infiniBand-capable systems, such as exalogic, ZfS Storage appliances, and so forth, you should take these
restrictions into account.

Note

How It Works
Again, completing your pre-delivery survey should be the easiest thing you'll have to do as part of an Exadata
Database Machine order and deployment. You need to ensure power specifications are correct and the internal and
site delivery information is accurate.
If you happen to specify the wrong power requirements, you won't be able to power your Exadata rack on.
Without being able to power the rack and its components on, you will not be able to install and configure your
machine. To correct this, you will either have to install proper power circuits in your data center or request a
re-shipment of either the correct PDUs or a rack replacement. In both cases, this will lead to delays and potentially
additional cost.
Internal and site delivery sections of the pre-delivery survey include information such as business hours, data
center security requirements, loading dock information, delivery truck restrictions, and so forth. Providing incorrect
information in these sections is not necessarily catastrophic, as an Oracle field engineer will conduct an on-site
pre-delivery survey to validate this information.
Each of the Exadata Database Machine configurations (Quarter Rack, Half Rack, and Full Rack) is shipped
in a standard 42U Oracle rack. Both the rack and packaging material dimensions are the same regardless of the
configuration you've purchased. Each configuration has different weights based on the components installed inside
the rack. These dimensions and weights are contained in the pre-delivery survey.

6-9. Completing the Configuration Worksheet
Problem
You are tasked with filling in Oracle's Exadata Database Machine configuration worksheet and need to understand
what the various fields mean and why they are important.

Solution
The configuration worksheet has four sections that require customer input:

• Default Oracle Environment Settings

• General Configuration Worksheet

• Network Configuration Worksheet

• Cell Alert Delivery Configuration Worksheet

The Default Oracle Environment Settings section is intended to specify the Oracle software owners and groups on
the compute nodes, default password(s), Oracle base and home directories, database name, character set, and block
size, as well as the ASM disk group prefix for database storage, and the starting IP address for the InfiniBand network
(typically 192.168.10.1 ), and so forth. In other words, this section allows the customer to configure their Oracle
operating environment on the compute nodes.
