Administration and Diagnostics
Utilities

Exadata provides several interfaces and utilities to help access, monitor, and generate diagnostics for Exadata
hardware components. In this chapter, we will present and provide usage details for many of the more common
administration tasks and utilities than an Exadata Database Machine administrator (DMA) will perform.

■ My Oracle Support document 1274324.1 provides updated information on the topic of Exadata X2-2 and X2-8
diagnostics and troubleshooting best practices.

Note

7-1. Logging in to the Exadata Compute and Storage Cells
Using SSH
Problem
You wish to log in to your Exadata Storage and Compute Servers as root , the Oracle software owner, or the Grid
Infrastructure owner.

Solution
Each Exadata compute and storage node is accessible using Secure Shell (SSH) via the administration (management)
interface. You will have registered your server names in DNS by the management network interface, as is presented
in Recipe 6-2. From a shell or DOS prompt, ping your servers by their hostname and you will see the management
interface:
