This document discusses indexing in Oracle Exadata. It begins by providing background on the speaker and their experience. It then discusses how Exadata storage server software, including hybrid columnar compression and smart flash cache, can accelerate queries. The document shows an example of how a query that previously took minutes can take seconds on Exadata due to smart scans. It discusses how indexes may no longer provide benefits and can even reduce performance on Exadata. The document considers whether indexes should be dropped or if the decision is more complex. It analyzes the costs of using indexes versus full table scans on Exadata. Finally, it provides examples to illustrate smart scans.
This document summarizes new features in Oracle Database 12c Release 2. It outlines features for developers, administrators, SQL*Plus, conversion functions, and more.

Tuning SQL for Oracle Exadata: The Good, The Bad, and The Ugly Tuning SQL fo...Enkitec
This document discusses tuning SQL on Oracle Exadata. It makes three main points:
1. Gathering and displaying execution plan data differs slightly on Exadata compared to non-Exadata databases.
2. The general approach to optimization is similar to non-Exadata, focusing on features like smart scans, storage indexes, and parallelism that provide the most benefit.
3. Rewriting SQL queries can have a dramatic impact on performance by enabling offloading and reducing disk I/O, with examples showing savings of over 98% in run time.
Oracle Real Application cluster evolves with each release. There are some important features added in Oracle 11GR2.

The document provides a critical review of the Oracle Exadata X2-8 system. It summarizes that Exadata combines Oracle database software with specialized hardware including flash storage and servers. While Exadata promises high performance, it relies on older disk technology and is very expensive, costing over $9 million for hardware and software licenses. Alternative configurations using newer flash storage technologies from other vendors can provide similar or better performance at a lower cost without locking the customer into Oracle's platform.

Collaborate 2019 - How to Understand an AWR ReportAlfredo Krieg
This document is a presentation on understanding Oracle AWR reports. It discusses key concepts like database time, time consumed vs time waited, and identifying bottlenecks. The main points are:
- Database time (DB time) represents the total time spent in database calls and indicates the total workload.
- Time is divided into time consumed on CPU vs time waited for I/O or other waits.
- Bottlenecks are identified by analyzing wait events and seeing what sessions are waiting on most.
- The goal is to analyze DB time, see if the system is CPU-bound or I/O-bound, and identify the top SQL statements causing the bottleneck.
Oracle Database 12c includes several new features:
1) Online statistics gathering improves optimizer performance by gathering statistics for new objects during creation instead of requiring a full data scan later.
2) Invisible columns allow adding a column to a table without showing it in SELECT queries or the table definition unless explicitly specified.
3) Multiple indexes on the same column are now supported if they differ in characteristics like being unique/non-unique or using different index types.
The document discusses several new features in Oracle Database 12c including:
- A new multi-tenant architecture using container databases and pluggable databases.
- Enhanced threaded execution that reduces the number of processes required.
- Ability to gather statistics online during direct-path loads instead of full table scans.
- Option to keep statistics on global temporary tables private to each session.
- Introduction of temporary undo segments to reduce undo in the undo tablespace.
- Ability to add invisible columns to tables.
- Support for multiple indexes on the same column.
- New information lifecycle management features like heat maps and data movement.
- Ability to log all DDL statements for troubleshooting.
