1.2.1.1 Powering On Oracle Exadata Rack

Oracle Exadata Rack is powered on by either pressing the power button on the front of the servers, or by logging in to the ILOM interface, and applying power to the system. When a database server is powered on and the operating system boots, Oracle Clusterware is automatically started, if it is installed. Oracle Clusterware then starts all resources that are configured to start automatically.

The power on sequence is as follows:

1. Rack, including switches.

   Ensure the switches have had power applied for a few minutes to complete power-on configuration before starting Exadata Storage Servers.

2. Exadata Storage Servers.

   Ensure all Exadata Storage Servers complete the boot process before starting the database servers. This may take five to ten minutes before all services start.

3. Database servers.
