PDFFundamentals of Troubleshooting (without graphics)

Published: 22.01.2015 - This document is restricted to members

There are only three ways you can waste resources on an Oracle system, and only three different types of activity that need to be investigated. If you don't appreciate this then you can waste a lot of time following the wrong strategy. During two sessions we discuss the strategic side of trouble shooting and move on to the mechanisms we can use in a non-graphic environment to follow the correctly selected strategy. Presented by Jonathan Lewis at the Database Server SIG on 29th January 2015.

PDFA First Look at Oracle's In-Memory Database

Published: 21.10.2014 - This document is restricted to members

In June 2014 Oracle launched the in-memory database option and it is generally available as part of Oracle 12c (12.1.0.2) as an additional cost option to Oracle Enterprise Edition. But
what’s the big deal about in-memory (IM)?

PDFAn Introduction to Oracle SQL Developer Data Modeler

Published: 21.10.2014 - This document is restricted to members

Oracle SQL Developer Data Modeler (Data Modeler) is a tool for designing and documenting
databases. It can be used for Oracle databases as well as Microsoft SQL Server or IBM DB2 databases. The tool is available as standalone product but it is also integrated in Oracle SQL Developer, so a user can decide which way is the best for him/her to use the tool.

PDFCBO Choice Between Index & Full Scan: The Good, the Bad & the Ugly Parameters

Published: 21.10.2014 - This document is restricted to members

Usually, the conclusion comes at the end. But here I will clearly show my goal: I hope I will never see the optimizer_index_cost_adj parameters again. Especially when going to 12c where Adaptive Join can be completely fooled because of it. Choosing between index access and full table scan is a key point when optimising a query and historically the CBO came with several ways to influence that choice. But on some systems, the workarounds have accumulated one on top of the other – biasing completely the CBO estimations. And we see nested loops on huge number of rows because of those wrong estimations.

PDFData Warehousing Trends & Opportunities

PDFGoing Mobile: From Concept to Delivery

Published: 21.10.2014 - This document is restricted to members

Throughout this website you will no doubt see articles from leading experts in a whole
range of technologies, using their years of experience to successfully implement solutions
on the Oracle stack. Well in this article I want to tell a slightly different story: a story of how an applications DBA, rather than someone from a development background, managed to
end up successfully designing and building a production on-device mobile application for
Lloyd’s Register. If you want to learn the lessons, and maybe start building your own mobile
applications, then read on!

PDFOracle Application Express: Dispelling the Myth

Published: 21.10.2014 - This document is restricted to members

I sometimes hear the myth that Oracle Application Express (APEX) is only suitable for small projects and department systems. This could not be further from the truth; Oracle Application Express is exceptional, mature and a very scalable development platform.
