Oracle Magazine–Fall 1993

Posted on

The headline articles of the Fall 1993 edition of Oracle Magazine included topics on Multimedia Servers, Free Space Defragmentation and Geographic Information Systems.

Apart from the head line articles most of the other articles were about product announcements/updates and about how certain types of companies were using IT.

The main technical article was by Kevin Loney on freeing up free space in an Oracle 6 database using defragmentation. This was a popular topic for Oracle version 6 and 7, when disk space was expensive. It is less of an issue today.

There was an article on the Digital Highway and in Multimedia Servers. These were early indicators of Larry’s investing in the Video On-Demand servers.

The first maintenance release of Oracle 7 database was announced (Oracle 7.1), with enhancements centred around:

  • Parallel Operations : performance increases, splitting of query execution, data loading and index creation tasks and execute them concurrently on multiple CPS. Permits multiple sessions running SQL*Loader using the fast bulk load i.e.direct path
  • Application Development : Users can now embed PL/SQL functions in SQL statements and reference those functions in SQL expressions as if they are build-in.
  • Administration : Tablespaces can be placed in read-only mode. Provides a parallel recovery mechanism.
  • Standards Compliance : Oracle 7.1 is compliance with the SQL92 Entry Level standard. The ORDER BY clause can not reference SELECT list items names with a column alias.

Some of the products discussed in articles included Pro*C version 2.0, SQL*Module version 1.0, OracleWare, Oracle Graphics version 2.0, SQL*Net version 2 on MVS, SQL*Connect to SQL/400 and Oracle Card 2.0.

Apart from these product related articles, some others of interest included an advertisement for ERwin which was a product owned at that time by Logic Works.

There was a short article on the IOUG 12th Annual User Group Conference in September.

Oracle Magazine–Winter 1993

Posted on

The lead articles in the first Oracle Magazine of 1993 (winter) were about how the Oracle database was being used in the Toronto Stock Exchange and in the Municipio de Panama of Panama City.

Other articles of interest included

  • Cary Millsap on the Optimal Flexible Architecture. Was this Cary’s first article in Oracle Magazine ? OFA provided a set of guidelines on how to install Oracle so that performance is not affected as your database environment grows. Cary gives 3 basic rules for creating and ODA compliant Oracle database (the full set is in the article).
    1. Establish and orderly operating system directory structure in which any database file can be stored on any disk resources (applicable to operating systems with hierarchical directory structures only).
    2. Separate groups of segments with different behavior into different tablespaces.
    3. Maximize database reliability and performance by separating database components across disk resources
  • There was 2 articles that looked at OODBMS. Oracle made their first purchase of an OODBMS company in 1994 and were trying to release their first OODBMS product in 1995. This never happened and their reverted to integrating some OODBMS features into the database instead.
  • Oracle Glue is released. This product has gone through a number of name changes since. What is it called now ?
  • There was a couple of articles discussing using UNIX or ALPHA server machines, when VLDBs were considered extremely large at 32GB. I remember there was one Bank who had the largest database in Ireland in 1993 and it was 4GB. I wonder what it is now.
  • Business Object announces the release of their DOS and Windows end user data access tool for relational database tool.
  • There was a number of adverts from companies providing tools and support for converting your Oracle Forms Version 2 to Forms 3

Oracle Magazine-Fall 1992

Posted on

I’ve been collecting Oracle Magazine for almost 20 years now. I have almost the entire collection, but I’m still missing some of the editions. Some people have donated some of the editions I was missing. But I still missing some.  Can you help me ? Check out my Oracle Magazine Collection.

Every 2 to 3 weeks I intend to write a blog post on each of the Oracle Magazines that I have, starting with the earliest edition that is from Fall 1992.

The main theme of the Fall 1992 edition was about the new Oracle 7 Database. I didn’t get using an Oracle 7 Database until mid-1994.There are a few customer case studies of Oracle 7 implementations. In the article Migrating to Oracle 7, they list some of the new feature. The following is an extract from the new features section.

Standard Oracle 7 provides the functionality and performance to tackle most mission critical applications:

– Multithreaded server
– Shared SQL
– Cost Based optimiser
– Row level locking
– Declarative integrity
– Role based security
– 100% ANSI/ISO standard SQL
– Enhanced national language support

The procedural option for Oracle 7 provides additional capabilities that enhance the database server in the application environment:

– Stored Procedures and Functions
– Procedure packages
– Database Triggers
– Lock manager package
– Database alerts

The distributed option for Oracle 7 makes a physically distributed database appear as a single, logical database. Features of this option include:

– Distributed updates
– TP monitor (XA) interface
– Transparent two-phase commit
– Remote procedure calls
– Table replication (snapshots)
– Oracle Mail Interface

Another article that stands out is by Richard Barker (do you remember his?) who was responsible for the CASE*Method and Oracle’s CASE Tools.

There was several articles on the new Oracle Forms 3 and Oracle Menu 5. Talking about some of the new features like List of Values (LOVs), pop-up Field editor and Pop-up Pages.

There also also the first articles on using Oracle a Microsoft Windows environment. Oh how I remember the frequent blue screens when developing and compiling my forms and in particular my report, with does early releases on Windows.

 

The editorial staff of Oracle Magazine have kindly given me permission to make a PDF of the front cover and the table of contents available for each edition. To get this PDF click on the above image or follow this link to see what Oracle Magazine used to look like 20 years ago.

My next blog post on Oracle Magazine, will look at the Winter 1993 edition.

If you have any of the editions that I’m missing from my collection and you would like to donate then, then drop me an email and we can arrange delivery.  You wont see any of them on eBay, I promise.

New additions to my Oracle Magazine Collection

Posted on

I put out a call a few months ago looking for help in completing my Oracle Magazine collection. I also had a letter in the Nov/Dec 2011 edition of Oracle Magazine looking for help.

The following people contacted me in December offering to send me some of my missing editions.

Lisa Dobson – Oracle DBA at Durham University and Vice President of UKOUG
Debra Lilley – President of UKOUG
Christian Antognini – Trivadis AG, Switzerland
Dan Vlamis – Vlamis Software Solutions, MO, USA

Many thanks for your donations.

It seems that people don’t keep their Oracle Magazines!

I’m now just missing a very small number of editions since 1992.  Can anyone else help ?

Does anyone have any Oracle Magazines from before 1992 ?

The following table gives the current collection (printed editions). The grey boxes are the editions that I’m still missing, and keep an eye on my Oracle Magazine page for updates.

ODM 11gR2–Real-time scoring of data

Posted on

In my previous posts I gave sample code of how you can use your ODM model to score new data.

Applying an ODM Model to new data in Oracle – Part 2

Applying an ODM Model to new data in Oracle – Part 1

The examples given in this previous post were based on the new data being in a table.

In some scenarios you may not have the data you want to score in table. For example you want to score data as it is being recorded and before it gets committed to the database.

The format of the command to use is

prediction(ODM_MODEL_NAME USING )

prediction_probability(ODM_Model_Name, Target Value, USING )

So we can list the model attributes we want to use instead of using the USING *  as we did in the previous blog posts

Using the same sample data that I used in my previous posts the command would be:

Select prediction(clas_decision_tree
USING
20 as age,
‘NeverM’ as cust_marital_status,
‘HS-grad’ as education,
1 as household_size,
2 as yrs_residence,
1 as y_box_games) as scored_value
from dual;

SCORED_VALUE
————
           0

Select prediction_probability(clas_decision_tree, 0
USING
20 as age,
‘NeverM’ as cust_marital_status,
‘HS-grad’ as education,
1 as household_size,
2 as yrs_residence,
1 as y_box_games) as probability_value
from dual;

PROBABILITY_VALUE
—————–
                1

So we get the same result as we got in our previous examples.

Depending of what data we have gathered we may or may not have all the values for each of the attributes used in the model. In this case we can submit a subset of the values to the function and still get a result.

Select prediction(clas_decision_tree
USING
20 as age,
‘NeverM’ as cust_marital_status,
‘HS-grad’ as education) as scored_value2
from dual;

SCORED_VALUE2
————-
            0

Select prediction_probability(clas_decision_tree, 0
USING
20 as age,
‘NeverM’ as cust_marital_status,
‘HS-grad’ as education) as probability_value2
from dual;

PROBABILITY_VALUE2
——————
                 1

Again we get the same results.

My first set of Oracle Products

Posted on

I started working with Oracle back in 1993 and my first project involved working with Oracle 5, Forms 2.3 and for reports RPT.

The Oracle Database and tools were very simple back then, but there was lots of “features” to work around.

Check out this video, for a short demo of Oracle 5 and Forms 2
