In the world of Oracle Exadata, performance is king. And at the heart of that performance lies the RDMA over Converged Ethernet (RoCE) Network Fabric. Whether you are running an X9M, X10M, or the latest X11M, keeping this fabric updated is critical for maintaining low-latency, high-throughput communication between your database servers and storage cells.
Oracle Auto Service Request (ASR) is the built-in mechanism that turns Exadata hardware and software faults into automatically opened Service Requests (SRs) with Oracle Support, no phone calls, no manual ticket creation. When a disk fails at 3 AM, ASR detects it, files the SR, attaches telemetry, and can even initiate parts dispatch.
There are two main ways to get bulk data into Oracle Exadata: load it directly through an integration server like GoldenGate, or stage files first and load them with external tables or SQL*Loader. This post compares the four staging options (ACFS, DBFS, SAN, and NAS), covering how each works, its trade-offs, and how to choose between them.
A walkthrough of how Oracle RAC instances and database services behave when one database node (holding one RAC instance and two database services) fails or is taken offline for patching.
Oracle Exadata Smart Scan is one of the most important performance features of the Exadata Database Machine. It pushes parts of SQL processing—mainly predicate filtering and column projection—down to the Exadata storage cells. Instead of sending every block from storage to the database tier, the storage cells scan the data, apply eligible WHERE conditions, return … Continue reading Exadata Smart Scan Preventors
Oracle Exadata Hybrid Columnar Compression (HCC or EHCC) is a storage-dependent compression format. It is supported on Exadata and selected Oracle storage platforms, including Oracle ZFS Storage Appliance, Pillar Axiom, FS1, SuperCluster, and Oracle Database Appliance (latest releases). It is not supported on ordinary third-party or non-Exadata storage. If you have a Data Pump export … Continue reading Migrating Oracle HCC-Compressed Tables to Non-Exadata with Data Pump
