Exadata

Migrating from Exadata X7 to X11M is not a simple hardware swap — it is a generational architectural shift. The X11M introduces RoCE (RDMA over Converged Ethernet) replacing InfiniBand, PCIe Gen5 NVMe replacing earlier NVMe tiers, and a new compute architecture with AMD EPYC processors. This article provides an in-depth, end-to-end playbook for architects and senior DBAs planning this migration. Reference Environment All commands in this article use the following concrete hostnames and roles. Every code block identifies which server and user account the command runs from. ...

The Oracle Exadata Deployment Assistant (OEDA) is the mandatory tool for configuring and deploying Oracle Grid Infrastructure and Oracle Database on Exadata hardware. It generates the configuration XML that drives the automated install.sh deployment script, eliminating manual installation error. This article covers the full OEDA workflow — from GUI configuration through XML generation to deployment execution — with real-world examples. What OEDA Does and Does Not Do OEDA does: Configure networking (public, private/InfiniBand/RoCE, management/ILOM, admin) Define cluster nodes, ASM disk groups, and storage configuration Configure Grid Infrastructure (GI) and Oracle Database parameters Generate the install.sh script and all supporting XML/config files Validate the configuration before deployment (via --check) OEDA does not: ...

If you are running workloads on Oracle Exadata, you are likely sitting on a goldmine of performance capability. The most significant differentiator between Exadata and traditional storage architectures is a feature called Smart Scan (also known as Cell Offload Processing). Instead of treating storage as dumb disks that just serve blocks to the database, Exadata pushes SQL processing down to the storage tier. This article explains how Smart Scan works, how to verify it, and how to control its behaviour for testing. ...

The Exadata X11M platform separates database compute and storage cells connected via an RDMA-capable RoCE fabric. This page summarizes hardware variants and provides practical command-line examples for common administration, troubleshooting and monitoring tasks. Architecture Overview Database Servers (Compute) These servers run the database and client-facing workloads. Standard Exadata X11M Database Server CPU: 2x 96-core AMD EPYC 9J25 (192 physical cores) Memory: 6400 MT/s DDR5, 512 GB–3 TB Local storage: 2x 3.84 TB NVMe (OS / Oracle binaries) Exadata X11M-Z Database Server (Entry) ...
