Application Development

That’s Not Where I Want That!
Jorge Rimblas, Enkitec
Room 505            1:00 – 3:00 PM

You’re creating Application Express (APEX) applications already, but you wish your screens would look better. Moving regions around, changing their size, width, placing items and buttons—it’s all frustrating and painful. In this session, you’ll learn how to position your elements and better implement the vision you have for your applications. We’ll go into details of the attributes provided by APEX to make this happen as well as learn some HTML and CSS that will allow you to personalize your applications. You’ll be more comfortable with CSS and how it really works.

Hands-on Introduction to Oracle Application Express
Jennifer Kreie, New Mexico State University
Room 502/503      1:00 – 3:00 PM

This workshop is a hands-on introduction to Application Express (APEX) for people who have little or no experience using APEX. Handouts, online SQL scripts, and twenty videos provide exercises that introduce several APEX tools and features. Workshop attendees will: 1. Create an APEX workspace in the XE interface. 2. Use APEX Administration to create a developer account for that workspace. 3. Use APEX SQL Workshop to run scripts that create and populate tables. 4. Use APEX Application Builder to generate an application with a simple data entry form, a master-detail form, reports (classic and interactive), and a LOV (list of values/combo box) to use in data entry forms. Prior to the workshop, attendees should install Oracle XE on their computer or have developer access to an APEX workspace via the Internet (such as apex.oracle.com). Online scripts for the tutorial are at: http://web.nmsu.edu/~jkreie/oracle/DatabaseTopics.html and videos are at (1st in series): http://www.youtube.com/watch?v=JgWQJUsyLVU.

DBA Deep Dive

Practical & Efficient SQL Performance Tuning
Vlado Barun, Oracle Corporation
Room 506            1:00 – 3:00 PM

Active Session History (ASH) and Automatic Workload Repository (AWR) represent a rich repository of performance statistics. But where do you start and how do you integrate these resources into a practical method for SQL performance tuning? Attend this session to learn how to rapidly determine and resolve root causes of SQL performance issues using ASH and AWR. We will use real production issues to demonstrate step-by-step how to resolve complex SQL performance problems. By the end of this deep dive, you will have gained a practical understanding of ASH and AWR and a set of SQL scripts to use in your own SQL performance tuning efforts.

Certifying Application Performance on Exadata – A Real-World Case Study
Gaja Vaidyanatha, DBPerfMan LLC
Room 504            1:00 – 3:00 PM

Seems like yesterday, but Oracle Exadata is almost four years old. In its time, it has evolved as the preferred and quintessential database solution for large mission-critical Oracle systems and database consolidation efforts. This two-hour talk shares all relevant technical information pertaining to an application performance certification effort, performed for an ERP application suite on an Exadata X2 system. The presentation will delve deep into the details of the setup and configuration of the Exadata system, including but not limited to Oracle initialization parameters, storage layout, partitioning, parallelism, low-level application traces, relevant WebLogic configuration details and Oracle*Net optimizations. Bottom line is all technical decisions need to be driven by mathematical data not expert opinions.

NoSQL and Big Data for the Oracle DBA: Can RDBMS Handle the Performance, Scalability, and Availability Demands of a Wired World?
Iggy Fernandez
Room 501            1:00 – 3:00 PM

NoSQL and big data have a lot of momentum and even Oracle Corporation has joined the fray with its own NoSQL offering and Hadoop connectors. The NoSQL and big data camps claim that relational technology cannot handle the performance, scalability, and availability demands of a wired world. In this session, Iggy will demystify NoSQL and big data and survey the new product landscape. Iggy will then explain that the deficiencies of relational technology are actually a result of deliberate choices made by the relational movement in its early years. The relational camp needs to revisit these choices if it wants to compete with NoSQL and big data technologies in the area of performance, scalability, and availability. Iggy will:

• Demystify NoSQL using the example of Amazon Dynamo
• Compare the novel approach of Amazon with the conventional approach of eBay
• Survey the NoSQL and big data landscape, including the Oracle NoSQL solution
• Explain what makes relational technology so sacred
• Identify the missteps of the relational camp

Advanced ASH Architecture and Usage
Graham Wood, Oracle Corporation and John Beresniewicz, Oracle Corporation
Room 507            3:15 – 5:15 PM

Active Session History (ASH) was introduced with Oracle 10g and remains an important tuning and diagnostic tool today. Moving on from using ASH data to derive DB Time, we will look at how we can use ASH to get an estimate of average latencies for different events. This allows us to use ASH to better understand what sessions were doing in the past, allowing us to troubleshoot systems more effectively.

Combining Adaptive Cursor Sharing Flexibility with SQL Plan Management Stability
Carlos Sierra, Enkitec
Room 502/503     3:15 – 5:15 PM

Adaptive Cursor Sharing (ACS) is known to offer multiple execution plans for a given SQL. This flexibility causes some plans to show and go over time. In most cases, this behavior is fine and unnoticed. SQL Plan Management (SPM) offers significant control over which execution plans can actually be used. With SPM, we obtain a high degree of plan stability. At first sight, it looks like ACS and SPM work on opposite directions. The former promotes plan flexibility and the latter plans stability. Both characteristics are very desirable. The question is: How do ACS and SPM work together? In this two-hour session, both ACS and SPM are explained and demonstrated in detail. You will learn how ACS actually works as well as some limitations that cause it to not be fully activated. You will also learn how to implement SPM so it can complement ACS. Using the duo ACS-SPM, you can benefit from both with plan flexibility and stability.

Compression in Oracle Database

Ace DirectorTim Gorman, Evergreen Database Technologies
Room 1c/d      3:15 – 5:15 PM

There are several different types of compression available in the Oracle database for compressing table data, and so the question must arise: Which are most appropriate, and for which purpose? This presentation will discuss all the different types of table data compression in Oracle database (i.e. basic/advanced de-duplication compression and hybrid-columnar compression) as well as some older, often-forgotten techniques for fitting more data into less space. The presentation will begin with a brief review of data compression in general, followed by a review of the formats used for storage in database blocks and rows, the latter supported by block dumps. All of this will be a prelude for a knowledgeable discussion of the advantages and disadvantages of each type of table compression in Oracle.

Selectivity and How Oracle Calculates It

Ace DirectorJonathan Lewis, JL Computer Consultancy
Room 504      3:15 – 5:15 PM

This presentation explains the model (including weaknesses) that Oracle uses to calculate selectivity (fraction of data required) for many of the most common predicates. Understanding selectivity will help you when debugging bad SQL.

Introduction to Java and the Essbase Java API + Next Generation Essbase Outline Extractor Tips and Tricks
Ace Director
Tim Tow, Applied OLAP
Room 501            3:15 – 5:15 PM

Double your knowledge during this two-hour session. Over the years, many Essbase customers and partners have customized their applications with the Essbase Visual Basic, or “VB” API. As Microsoft support for VB ended over eight years ago, the writing is on the wall for those customers still running applications written using the VB API. The logical choice for building modern applications on the Essbase platform is Java and the Essbase Java API. Learn the basics of how to get started with the Java programming language and the Essbase Java API.

Once you have a basic understanding of what the Essbase Java API can do, see how it has been used to provide new capabilities in the Next Generation Outline Extractor. The free Next Generation Outline Extractor utility is the follow-up to the classic OlapUnderground Essbase Outline Extractor used by thousands of Essbase customers.
