It’s no secret that I am a die hard Toad^® fanatic. There are many reasons for this, but the one I want to talk about today is one of Toad’s best kept secrets: a commercial-grade FTP client built right into Toad!

As we all know, there are many factors that influence the performance of your application. Proper memory allocations, physical design, how the SQL is written and workload all affect the way your queries perform. One of most overlooked parts of testing an application is testing queries under production workload conditions.< ...

I don't know about you, but I sometimes write code that (inadvertently, not on purpose) contains an infinite loop. So I run my program and Toad goes off into never-never land, with Oracle chewing up CPU cycles so intently that it is hard to connect as SYS and kill the session.

For more than 10 years now, Toad has been THE tool for Oracle developers, DBAs, and analysts.  A few years ago, Quest began introducing versions of Toad that brought native support to popular platforms such as

Kudos to Alex Nuijten for bringing this gem to light, he wrote in his latest AMIS blog entry that:

Oracle 11g is out for Linux – and like every new release, there’s tons of cool new stuff. So over the next few weeks, I will write about some of Oracle 11g’s new features. This week, I’ll look at Virtual Columns and Virtual Indexes.

We all know that “a picture is worth a thousand words,” so I provided a few pictures (shown below) to try and briefly yet succinctly explain what ASM is and how it’s different than the previous ways of managing disk space within Oracle.

Ever hear people say they miss the good ole days – when times and things were much simpler than now? Well the same is true for Oracle DBAs, the early 90’s (circa 1993) were much simpler in terms of hardware selection for an Oracle server as summarized below.

Your Mission: Go fix ALL of the slow SQL in your application ASAP.

I use Toad® for Oracle almost everyday to tune and optimize problematic databases for customers, partners and friends. And I noticed that I followed a pattern – which seemed consistent across all such attempts. And although I wrote the whitepaper “

I offer in this Quseful (Quick and Useful) a package that you can use to dynamically retrieve the value of almost any column from any table. I created this package as a "helper" utility for Quest

What the heck is that?

Probably the single most painful task in data modeling (or any modeling for that matter) is switching tools. Forget the high direct costs like purchasing licenses and the obvious indirect costs of retraining your staff, because it’s the migration of all your meta-data from one tool to the other that looms large on t ...

Hypocrisy has got to be one of the most infuriating traits of human beings.

Quest Recursive SQL Transformation technology is an innovative AI technology that simulates human SQL transformation technique. It incorporates a set of transformation rules to transform SQL statements on a section-by-section basis. This replaces the trial and error method used by human to rewrite the syntax of a SQL statement. Each t ...

Qusefuls #1 and #2 were published on Steven Feuerstein's personal blog at feuerthoughts.blogspot.com.

I’ve been searching for a definitive answer to the question: “What is the cost of poor database design?” No doubt you have all seen the cost/benefit graphs for fixing application problems and the pyramid showing how up to 90 percent of performance issues in a running database are SQL and ind ...

It is Wednesday, May 09, 2007 and I am sitting in the Admiral's Club at the Buenos Aires airport. I just finished two days in this lovely city. My first day was spent enjoying the chilly, but very sunny afternoon, walking for four hours around the city. It is a busy, busy place with many buses throwing way too much gritty exhaust into the air (hey, ...

You’ll have to forgive me for spoofing the famous movie line “We don’t need no stinking badges” (Treasure of the Sierra Madre, 1948 and Blazing Saddles, 1974), it just seemed quite apropos

In my last blog entry we looked at sizing tables in 10g, of course the other side of that coin is the sizing of indexes. As with tables the Oracle8 manuals had an explanation of how to size indexes, but manuals since then have been strangely silent on the subject. In this blog I will address the sizing of normal, b-tree ...

I rediscovered the joy of writing to myself a week ago, and I also was reminded of the danger of coding in isolation (that is, working by oneself).

In this blog, I want to introduce you to a little known feature in Toad for Oracle called the PL/SQL Profiler. Believe it or not, the profiler has been in Toad since September 1999 (Version 6)!

In this installment I thought I'd write about the exciting, and soon to debut, Toad Data Modeler 3.0 release rather than yet another boring academic or technical topic on data modeling. TDM 3.0 is quite exciting. While it has not yet been made available for public beta – it will be very soon (so please email the product manager

On one of my first Oracle consulting assignments I had to come up with the sizing estimates for tables for a data warehouse for a telecommunications company in California. At that time, (1994) there were few products that provided sizing al ...
