With the recent release of Oracle Database 10g, OTN have recently been running a series of articles by Arup Nanda entitled "Oracle Database 10g: The Top 20 Features for DBAs".

With this in mind, I thought it worth putting something similar but this time focusing on those features that apply to Data Warehousing and Business Intelligence. So here's my Top 10...

Candidate keys: Choosing the right primary key

It is the business that has the knowledge about their entities (things of importance) and what kind of unique information that separate them (invoice numbers, customer IDs, and so on).

Your role as an analyst/designer is to validate such properties, and to fit them into a normalized database model that reflects the needs of the business.

Many Oracle professional do not realize the important of having good statistics for the Oracle cost-based SQL optimizer (CBO). The CBO has received a "bum-rap" from some Oracle professionals who wonder why the CBO is generating sub-optimal execution plans for their SQL statements.

Oracle 10g New Features: Audit Enhancements

Oracle databases have many types of auditing features. In mandatory auditing, certain actions are always audited, regardless of the other audit options or parameters. Database activities, such as system startup and shutdown, are always recorded.

Oracle 10g New Features: Automatic SQL Tuning Process

SQL tuning is one of the challenging tasks faced by DBAs and developers. It is an interesting and creative, but at the same time, daunting task. Manual tuning of SQL statements requires a high level of expertise and experience to understand and design suitable access paths to yield better response times. It is also a time consuming process. Other challenges include periodic collection of statistics and an ever-changing workload. And in a typical application, there are just too many SQL statements to tune.

  • Self-Managing Database
  • Simplified Configuration of Shared Servers
  • Transaction Manageability
  • Simplified Statistics Collection
  • Extended Support for FGA (Fine Grain Audit)
  • Response File Creation during database install

Watching Your users' every move: All about SQL Tracing

One of the most important responsibilities of an Oracle Database Administrator or Performance Analyst, when it comes to performance diagnostics, is to determine how users access the database. This article is an attempt to show the different ways one can activate tracing of an Oracle session for performance diagnostics. While the Oracle documentation mentions some of the methods, it doesn't cover them all. This article consolidates many methods of tracing an Oracle session, some of which are well documented, as well as methods that are undocumented and reserved.
