Oracle Technology Network

OTN has links to two of my blog posts

Posted on

Over the past couple of weeks I’ve noticed that I had a bit of a spike in my blog stats (I don’t check them often). In particular there was 2 groups of blog posts that were getting a lot of the hit.

After a bit of investigation I found out that it was do to referrals from one particular website. It was OTN or Oracle Technology Network, and more specifically it was from their webpage dedicated for Database Admins and Developer.

Yes OTN had links to my blog posts on Clustering in Oracle Data Miner and to my blog post on Are you a Type I and Type II Data Scientists.

What a surprise this was to discover!!!  and what a honour Smile

I don’t know how long they will be on the OTN webpage, but hopefully lots of people in the Oracle community will find them useful.

I’m working on my next set of Oracle Data Miner blog posts, so watch this space. Plus I’ve started work on two technical articles that I’ll be submitting to OTN over the next few weeks. So hopefully you will see these up on OTN soon.

Oracle Magazine–March/April 1999

Posted on

The headline articles for the March/April 1999 edition of Oracle Magazine were on the evolving world of the DBA. With some much new technology available in the database the role of the DBA is moving from a back office type role to one having a significant strategic influence in the organisation.

Other articles included:

  • Oracle releases a web based version of their Oracle Strategic Procurement application that includes three key parts: Strategic Sourcing, Internet Procurement and Process Automation.
  • Sun and Oracle announce a strategic agreement that allows both companies to enhance their product offerings by exchanging key technologies. Oracle will use the core of the Sun Solaris operating environment to deliver the industry’s first database server appliances.
  • Oracle Data Mart Suite releases version 2.5. It includes, Oracle Data Mart Builder, Oracle Data Mart Designer, Oracle 8 Enterprise Edition, Oracle Discoverer, Oracle Application Server and Oracle Reports and Reports Server.
  • New integration between Oracle Reports release 6.0 and Oracle Express Server release 6.2 to give users the ability to distribute high quality reports of information held in a multi-dimensional database across the enterprise.
  • The need for the DBA to know and understand the V$ views has been increasing during the later releases of 7.3 and 8i. The can be used for a variety of purposes, including understanding locked users, system resources, licencing and parameter settings.
  • One thing that all DBAs need to plan for is a database recovery. Planning it is one thing, but practicing it is another thing. A typical recovery plan will include, choosing a data file, create a backup, take the damaged tablespace offline, restore the damaged data file, bring the tablespace back online, recover the tablespace, bring the tablespace back online and test it.
  • Avoiding trigger errors, including Mutating and constraining table errors.
  • There is an article by Bryan Laplante on using Historgrams to Optimize Data Mart Performance.

New features for Developers in Oracle 12c & Tools

Posted on

Continuing on from my previous posts on new features in the Advanced Analytics Option and the 12c Databases, this post will focus on the proposed new features for Developers in 12c and in the new releases of the development tools.

Health Warning: As with all the presentations at OOW that talked about what may be in or may be in the next release, there is no guarantee that these features will actually be in the released version of the database. Here is the slide that gives the Safe Harbor statement.

image

  • APEX 4.2 is out now and has lots of new features in particular features for creating mobile applications including transitions, gestures, changes in orientation and HTML 5 support. Coming in 12c APEX will be able to support the pluggable database environment. You will have the option to install APEX in the Contain database or in the pluggable databases. It will also support the extended VARCHAR2 size
  • SQL Developer will have Data Pump to allow for fast movement of data and for scheduling of the movements. The Database Difference tool has been redesigned to give more options and gives a more reliable comparison. A redesigned Database Copy (more options), improved Migrations and PDF report generation. SQL Developer is not the admin tool to manage the APEX Listener. UI improvements include more/better drag and drop, GRANT statement support in SQL editor and database Doc reporting. A new release of SQL Developer will be made available with the release of 12c that includes all the 12c new features
  • Better Data Compression of data being sent to/from the client/server. So how you use the ORDER BY clause will become more important
  • We will now have BOOLEAN in 12c but only in PL/SQL Sad smile
  • 12c will allow you to grant ROLES to PL/SQL program units. Or we could specify a White List that lists what other code units can call your code. This is a great security enhancement, although it involves more admin work, but it is worth it.
  • 12c will allow you to include PL/SQL in WITH
  • 12c will allow you to create duplicate indexes on the same set of columns. Sometimes you might want two different types of index on the same data, for example a bit map index and a b-tree index.
  • Cursor results sets can now be returned implicitly instead of the existing explicit method
  • The Warning messages when compiling our PL/SQL code can be filtered based on if they are Severe, Performance related or just Informational. This can be set at a System or Session level.

alter session set plsql_warnings=’enable:severe’;

alter session set plsql_warnings=’enable:performance’;

alter session set plsql_warnings=’enable:informational’;

There was a large number of exhibits at OOW. All of them were giving things away. For some of these you had to endure a sales pitch. One of the popular type of give away was a t-shirt. If you really wanted to, you could get enough t-shirts to keep you going for a few years. I popped into the exhibits for JavaOne and the pictures below is my faviourate t-shirt from OOW, by CloudBees.

Some of the exhibits were also giving away money. If you would sit through a 10 minute presentation you were given a ticket and if your number was picked your would could win anything from $20 up to $100. Many thanks to Intel Smile

  • The Egyptian Stock Exchange and Capital Market Authority implements a new trading system build on Oracle
  • Don Burleson in his article on Automating Oracle Tuning gives a number of scripts that would assist the DBA in finding out what is going on in the database. So instead of purchasing some expensive tools, all you needs was these scripts UTKBSTAT/UTLESTAT.

Oracle Magazine–Volume 1 Number 1

Posted on Updated on

A few weeks ago I sent a few emails to some well know names in the Oracle World looking to see if they have a copy of the very first Oracle Magazine (Volume 1 Number 1).

Many thanks to Oracle ACE Director Cary Millsap of Method-R, who responded to say that he had the very first Oracle Magazine. He kindly arranged to have it scanned into PDF.

To view the 12 page Oracle Magazine (Volume 1 Number 1) click on the following image.  Read and Enjoy!

Some people have said that his is not the first Oracle Magazine, published in June 1987. Although this edition is labelled as Volume 1 Number 1, an Oracle Newsletter existed for a few years prior to this edition.

Do you know of anyone who has these newsletters ?

VM for Oracle Data Miner

Posted on

Recently the OTN team have updated the ‘Database App Development’  Developer Day virtual machine to include Oracle 11.2.0.2 DB and SQL Developer 3.1.  This is all you need to try out Oracle Data Miner.

So how do you get started with using Oracle Data Miner on your PC. The first step is to download and install the latest version of Oracle VirtualBox.

image

The next step is to download and install the OTN Developer Day appliance. Click on the above link to go to the webpage and follow the instructions to download and install the appliance. Download the first appliance on this page ‘Database App Development’ VM. This is a large download and depending on your internet connection it can take anything from 30 minutes to hours. So I wouldn’t recommend doing this over a wifi.

When you start up the VM your OS username and password is oracle. Yes it is case sensitive.

When the get logged into the VM you can close or minimise the host window

image

There are two important icons, the SQL Developer and the ODDHandsOnLab.html icons.

The ODDHandsOnLab.html icon loads a webpage what contains a number of tutorials for you to follow.

image

The tutorial we are interest in is the Oracle Data Miner Tutorial. There are 4 tutorials given for ODM. The first two tutorials need to be followed in the order that they are given. The second two tutorials can be done in any order.

If you have not used SQL Developer before then you should work through this tutorial before starting the Oracle Data Miner tutorials.

The first tutorial takes you through the steps needed to create your ODM schema and to create the ODM repository within the database. This tutorial will only take you 10 to 15 minutes to complete.

In the second tutorial you get to use the ODM to build your first ODM model. This tutorial steps your through how to get started with an ODM project, workflow, the different ODM features, how to explore the data, how to create classification models, how to explore the model and then how to apply one of these models to new data. This second tutorial will take approx. 30 to 40 minutes to complete.

It is all very simple and easy to use.

The First Oracle Magazine–Volume1 Issue 1

Posted on Updated on

In my last blog post I reviewed the contents of the March/April 1996 edition of Oracle Magazine. While doing this I noticed on the Editors Pages, Julie Gibbs gave a review of the very first Oracle Magazine from 1987.

Here is the front cover of the first Oracle Magazine. I’ve scanned the editors page, containing the review. Just click on the image below.

527610_463186290364358_114144098601914_2017027_29908051_n[2]

The first edition had just 12 pages of content.

Here is the extract from the editors page March/April 1996:

The picture you see on this page is of the first cover of Oracle Magazine-Yolume I, Number I, June 7987. Yes, we are celebrating our tenth anniversary this year. Ten years may not seem like much in other industries, but in high tech, it’s a veritable lifetime. Companies and products have come and gone-where ate you now, VisiCalc? How about the PC jr? And who knew in 1987 that the Internet would be the dominant topic of the high-tech press in 1996?

What was in the first issue of Oracle Magazine? Here’s a sampling of articles in that 12-page fledgling publication: New Network Expands Customer Support (24-hour online support was introduced June I, 1987);
Oracle Version 5 .1 Released; Oracle RDBMS Now Available on Wang VS; Oracle Exceeds First HaIf Forecast (revenues for the first half totalled almost $46million); UniForum: Site of Oracle UNIX Announcements (at the time, Oracle ran on more than 20 platforms, including new
UNIX ports to NCR, Sun, DEC Ultrix,Sequent, Altos, and Plexus); SQL Declared Standard Language by ANSI; Double DEC Awards for Oracle (Digital Review’s Target Awards gave Oracle first place for “Best Database Management Product” and the No. I rating in the “Digital News 50”).

Some people say that Oracle Magazine existed before 1987. Oracle did have a newsletter type publication.

How big is your database ?  Oracle conducted a survey of all its customers to see what was the typical size of their databases and how many users each database would have. The following diagrams gives the results of this survey and compares the 1994 results with the results from 1993. We can see that there was a bit of a jump on the size of the databases but the number of users increased significantly

So must customers had databases in the 2GB to 10GB. How things have changed. If the survey was conduced for 2012 what results would be get ?

In 1995, Oracle Open World took place in Yokohama, Japan between 18th and 19th January. It had 130 seminars and sessions.  In 2012 OOW will have over 500 sessions and will run over 5 days!
