Oracle Exadata Tutorial

Welcome to the Oracle Exadata tutorial. Organizations focus on managing data workloads centrally so that the right insights had pulled from the data. Data redundancy is equally important as it acts as an extra protection layer for existing data systems in case of a disaster. Oracle Exadata enables the timely management of data and encompasses OLTP workloads. Are you looking forward to learning about Oracle Exadata? We are here to provide a basic level understanding of Exadata suitable for beginners in this Oracle Exadata tutorial for beginners. Let us get started.

What is Oracle Exadata, and what are its features?

Oracle Exadata is a database appliance designed for running Oracle databases and has released in the year 2008. It is available both on-premise and in Oracle cloud as a subscription service. It is a combination of the hardware and software platform that has computed and storage servers, networking, persistent memory (PMEM), NVMe flash, etc.

Exadata runs Oracle database workloads with Analytics processing. It allows mixed workloads to share resources with resource management features. Reports, batch jobs, analytics run many times faster in Exadata than in database servers. The actual computation has performed in the storage tier, which dramatically reduces the data transferred over the network.

Installation of Exadata rack

The environment requirements for Oracle Exadata Database Machine depend on the size of the system. Select an Exadata rack that suits your organization based on the requirements like flooring, network, etc. The Exadata rack size varies from full to quarter. The installation of an Exadata rack is quite complicated and should only have performed by rack installation experts.

  • Here are a few points to keep in mind before setting up the Exadata rack.
  • Install the Exadata rack on a flat and levelled surface.
  • Make sure the right power connectors have used for connecting the Exadata rack to the power source.
  • Do not place anything on top of the Exadata rack.
  • Do not install the rack near any equipment that generates electronic noise.
  • The temperature in the room should be constant. Do not expose it to direct sunlight.
  • Avoid static electricity at the installation location.
  • Do not pull any cords from the rack while the power is on.
  • Follow the documented procedure carefully for connecting the labelled inputs.

Once all the power cords are connected, switch on the PDU B circuit breakers one at a time. After the power LEDs are on, connect power to PDU A and switch on the circuit breakers.

Configuring Oracle Exadata Database Machine

Ensure that there are no IP address conflicts between the existing network and the new Oracle Exadata Rack. You can do so by executing the '' script. This script checks if the IP addresses and hostnames specified in Oracle Exadata Deployment Assistant (OEDA) has defined in the DNS. It also checks if the NTP servers and gateways are available or not.

  • The Oracle Exadata Database Machine involves the following configurations.
  • Configure the RDMA network fabric switch.
  • Set up the subnet manager master on the Exadata database machine rack.
  • Configure the Cisco Ethernet Switch.
  • Configure the power distribution units (PDU).
  • Configure the threshold settings for PDUs.
  • Log in to the database server and verify the SysSN label for the storage server.
  • Verify the RoCE network fabric configuration.
  • Verify the InfiniBand network fabric network.
  • Image a new system on the rack.
  • Perform the initial elastic configuration.

Once the above steps are complete, the Oracle Exadata Deployment Assistant (OEDA) loads the network settings configuration files and installs Oracle database software.
