OOW content/slides are still available

For those people who where lucky to get the Oracle Open World (OOW) and for all the many thousands of people who were not able to make it to OOW, the slides from almost all the presentations are still available.

To get your hands on these presentation slides, all you need to do is to go to the Oracle Open World website

http://www.oracle.com/openworld/index.html

Click on the Tools option on the menu and then click on Schedule Builder. You will need your Oracle Single-Sign-On username and password. Once entered you should get conference content and Schedule page.

You can search the content catalog for the presentations you are interested in and download the presentations.

There was been some mutterings that the presentation slides and access to the schedule build will be restricted at some time in the near future.

So get the conference material now.

While you are on the Oracle Open World site, why not sign up for notifications for the 2013 conference. They will probably start around early March.

ASCII to character conversion in Oracle

Here is code code that will produce formatted output of the characters and their ascii values. The formatting is broken into lower case letters, uppercase letters, characters with an ascii value less than an ‘a’ and characters whose ascii characters are greater than a ‘z.

Code

PL/SQL procedure successfully completed.

Observations

There are two things that stand out in this. The first is there is sound produced. This is because one of the characters is defined this way. It is ASCII number 7. This can be repeated using the following:

select chr(7) from dual.

The second is the formatting of the lines for ascii codes 8 to 12. We can see that one of the ascii codes does not get displayed and the ordering of this is not as expected. This is due to ascii 10 being a line feed.

New features for Developers in Oracle 12c & Tools

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.

• 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
• 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

Oracle Database next release (12c) new features

At Oracle Open World there was a number of presentation on the new features that we will see in the new release of the database, which is being called 12c, where c is for the cloud.

The 12c Database/Next Release was announce during Larry’s Sunday keynote speech. 

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.

In addition to this key note there was a few additional presentations on 12c with the main one, for me, by Tom Kyte on the Thursday morning.

• The 12c database will be a multi-tenant database. What does this mean? If means that we can have multiple databases running on the same server sharing the same memory and process management. Under the current configuration, when we create a new database on a server we create a separate set of processes and memory allocation.  Oracle is calling this, Pluggable Databases

• MapReduce in the Database - MapReduce can be run from PL/SQL directly in the database.
• Improved default value management. We will be able to clearly how to allocate a value to or calculate a value as a default for a column. The first of these is that we will be able to assign a sequence to a column. Example x int default s.nextval primary key. We can then insert into a table and not worry about how to calculate a primary key value, insert into t(y) values ('hello world');.  We will also be able to specify a default value when no value is being inserted into a column, z number default on null 42
• Increased size for VARCHAR2, NVARCHAR2 and RAW data types up to 32K in size. You will need to se the Max_SQL_String_Size in the init.ora to EXTENDED. But this new size limit is not supported in clustered and index organised tables.
• Some improvements to PARTITIONing, with asynchronous global index maintenance for DROP and TRUNCATE partition. New CASCADE functionality for TRUNCATE and EXCHANGE partition. You will be able to perform multiple partition operations with a single DDL command.
• There will be better Statistics for query performance including Hybrid Historgrams, Session Private Statistics and statistics will be gathered during data loads automatically.
• Temporary UNDO for objects will be handled in TEMP
• Greater insight of data usage i.e .what is being used or not being used and how frequently. This allows policies in table definition (new ILM clause) to compress or archive data after time.

ALTER TABLE orders
ILM ADD CompressionPolicy
COMPRESS Partitions for Query
AFTER 90 days from creation;

This post focused on the core database new features what may be coming in 12c.

In my next blog post I will look at some of the coding/development changes that are coming in 12c and associated Oracle development tools

Oracle Advanced Analytics Option in Oracle 12c

At Oracle Open World a few weeks ago there was a large number of presentations on Big Data and Analytics.  Most of these were marketing type presentations, with a couple of presentations on using R and how it can not be integrated into the Oracle Database 11.2.

In addition this these there was one presentation that focused on the Oracle Advanced Analytics (OAA) Option.

The Oracle Advanced Analytics Option covers the Oracle Data Mining features and the Oracle R Enterprise features in the Database.

The purpose of this blog post is to outline and summarise what was mentioned at these presentations, and will include what changes are/may be coming in the “Next Release” of the database i.e. Oracle 12c.

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 not guarantee that the features will actually be in the release version of the database. Here is the slide that gives the Safe Harbor statement.

• 12c will come with R embedded into it. So there will be no need for any configurations.
• Oracle R client will come as part of the server install.
• Oracle R client will be able to use the Analytics functions that exist in the database.
• Will be able to run R code in the database.
• The database (12c) will be able to spawn multiple R engines.
• Will be able to emulate map-reduce style algorithms.
• There will be new PREDICTION function, replacing the existing (11g) functionality. This will combine a number of steps of building a model and applying it to the data to be scored into one function.  But we will still need the functionality of the existing PREDICTION function that is in 11g. So it will be interesting to see how this functionality will be kept in addition to the new functionality being proposed in 12c.
• Although the Oracle Data Miner tool will still exits and will have many new features. It was also referred to as the ‘OAA Workflow’.  So those this indicate a potential name change?  We will have to wait and see.
• Oracle Data Miner will come with a new additional graphing feature. This will be in addition to the Explore Node and will allow us to produce more typical attribute related graphs. From what I could see these would be similar to the type of box plot, scatter, bar chart, etc. graphs that you can get from R.
• There will be a number of new algorithms too, including a useful One Class Support Vector Machine. This can be used when we have a data set with just one class value. This algorithm will work out what records/cases are more important and others.
• There will be a new SQL node. This will allow us to write our own data transformation code.
• There will be a new node to allow the calling of R code.
• The tool also comes with a slightly modified layout and colour scheme.

Again, the points that I have given above are just my observations. They may or may not appear in 12c, or maybe I misunderstood what was being said.

It certainly looks like we will have a integrate analytics environment in 12c with full integration of R and the ODM in-database features.

Extracting the rules from an ODM Decision Tree model

One of the most interesting of important aspects of a Decision Model is that we as a user can get to see what rules the machine learning algorithm has generated for our data.

I’ve give a number of examples in various blog posts over the past few years on how to generate a number of classification models. An example of the workflow is below.

In the Class Build node we get four models being generated. These include a Generalised Linear Model, Support Vector Machine, Naive Bayes and a Decision Tree model.

We can explore the Decision Tree model by right clicking on the Class Build Node, selecting View Models and then the Decision Tree model, which will be labelled with a ‘DT’ in the name.

As we explore the nodes and branches of the Decision Tree we can see the rule that was generated for a node in the lower pane of the applications. So by clicking on each node we get a different rule appearing in this pane

Sometimes there is a need to extract this rules so that they can be presented to a number of different types of users, to explain to them what is going on.

How can we extract the Decision Tree rules?

To do this, you will need to complete the following steps:

• From the Models section of the Component Palette select the Model Details node.
• Click on the Workflow pane and the Model Details node will be created
• Connect the Class Build node to the Model Details node. To do this right click on the Class Build node and select Connect. Then move the mouse to the Model Details node and click. The two nodes should now be connected.
• Edit the Model Details node, uncheck the Auto Settings, select Model Type to be Decision Tree, Output to be Full Tree and all the columns.

• Run the Model Details node. Right click on the node and select run. When complete you you will have the little green box with a tick mark, on the top right hand corner.
• To view the details produced, right click on the Model Details node and select View Data
• The rules for each node will now be displayed. You will need to scroll to the right of this pane to get to the rules and you will need to expand the columns for the rules to see the full details
