People are always asking me, ‘Jeff, what’s going to be in the new version of X?’ or ‘Jeff, what’s new in X?’ or ‘Jeff, what’s wrong with you?!?’ If I’m feeling particularly chippy, I’ll reply something along the lines of ‘How well do you think you’ve mastered the current version of X?’ If you haven’t seen something before, that means it’s new for you, right? I think that was a NBC promo ad back in…

Post Updated on November 10, 2011. 11gR2 was supposed to be 12g..or so the story goes. You can read tons of posts on OTN from several years ago where 12g is referenced. Nothing recent though. So… Oracle Open World 2011 is coming soon, and you know the Big Red Machine will want to have a big splash. Will it be a new version of their RDBMS solution? And for all those people who just got…

Sometimes I get a little preachy in my presentations. OK, maybe I get a LOT preachy. In exchange for being stuck with me for 90 minutes, I promise every person will receive at least one new technique or trick that will greatly affect their productivity when working with the database. Fortunately for me, most agree that this is a fair trade! Things generally go at a pretty rapid pace until I bring up one of…

Wanna keep track of changes to a table, and be able to query different versions of your data? Then check out Oracle’s ‘new’ feature – FLASHBACK ARCHIVE. From Oracle (docs) “…which provides the ability to automatically track and archive transactional data changes to specified database objects.” (BTW Whoopie has yet to portray a DBA, but we can keep our fingers crossed.) Automatically tracking and archiving data changes must have some sort of catch, right? What…

Apologies to Wynonna Judd for borrowing and mangling her lyrics and song title, but I just had a really interesting conversation with a fellow Oracle tools guru. We we’re discussing just how much functionality an end-user really takes advantage of in a software product. He had mentioned that users maybe exercises about 20% of a tool’s feature-set and I countered with 10%. Maybe we’re both wrong, but I think we are on the right side…

Disclaimer: When I wrote this I was not an employee of Oracle, a RDBMS vendor. I am now, and you should know that. First, please go read Karen Lopez’s rant on Normalization Myths here. Now, a bit of my experience with relational database theory, design, and practice. As a senior Computer Science undergraduate I took a 200 level course on ‘Databases.’ We were taught set theory, a bit of algebra, Boyce-Codd, what it means to…

You want to know how much pain you are going to inflict on the server and network before you run that ad hoc query? An explain plan can give you an idea of how long it might take to run, and tell you how much data it thinks will be involved. Cardinality – Fancy Word, Simple Concept From Wikipedia: “In mathematics, the cardinality of a set is a measure of the “number of elements of…

“Those people are fine, they JUST write SQL.” I often hear this in the context of visiting customers and offering to provide training (and yes, software) to their database users. There is a class of people who are deemed unworthy of such productivity tools because they do nothing but ‘just write dumb SQL all day long.’ The only problem is, I know that it’s these people that are largely responsible for running the business. When…

real time sql monitoring in oracle sql developer

Oracle 11gR1 Enterprise Edition with the Diagnostic and Tuning packs has a very compelling new feature, Real-Time SQL Monitoring. Oracle thinks enough of the feature that it was highlighted prominently in whitepaper by ACE Directory Arup Nanda titled “Oracle Database 11g: The Top Features for DBAs and Developers” (read it here) Long story short: Too late or too lazy to start a trace on a poorly performing query? Want to know what is going on…

I’ve been referring customers to SQL Developer’s Migration Workbench for a few months now. I thought it might be a good idea to give it a try myself before I send any more children out to play with the wolves. This is NOT a formalized review. This is a quick glance at a cool tool from a cool vendor. I did what all geeks do – I ran it without reading ANY of the product…

Coming up with themes and titles for a blog post can be very challenging. You want something that will catch the eye, but not be so random or out of left field that no one catches your drift. This morning I had two themes battling inside my head for this post. Welcome to the Jungle Baby! Pigs In Space You’re here so you already know who won. Pigs in space? Pigs don’t belong in space?!?!…

Do you just hand your keys to whoever wants access to your car or your house? Why do so with your database? Just because someone wants to look at ‘your’ data, doesn’t mean you have to let them in without asking a few questions, right? While the person won’t be driving your car, they’ll be driving data in your database. This could be one of the most important and valuable assets your organization has. Wouldn’t…

Ask questions, get answers – and a Toadie! He wants questions. You want answers (and a Toad). So, ask away – stump the Toad chump! We’re looking for challenging questions dealing with Oracle Database and Toad, for example: Can Toad do that? I had this problem once where… I hate it when… The Rules! If I like your question, you get a Toad beanie. I’ll answer any and all questions submitted. Please keep the questions…

Disclaimer: I work for Oracle now. This post pretty much pertains to any and all database IDE and GUIs. –Thanks, Jeff 1/25/2012 Let’s get this out of the way, because anyone who knows me, knows that I have a HUGE bias in this argument: I work for Quest Software, and my primary job is to help sell Toad for Oracle. I also love SQL*Plus, and I use it almost everyday. So don’t bash me because…

My database crashed today. My ‘production’ database that is. The one I rely on for product demonstrations, that thing I do that Quest gives me money for. Pretty funny considering in the last few weeks my blogs have included such gems as: Are You a Real DBA – I argue that you are indeed NOT if you have not went through the crash and recovery nightmare What Databases Should You Back Up – I argue…
