At 11:00 AM Pacific on Tuesday, October 25th (tomorrow), I have the privilege of talking about Cloud and on-premise (ground) integration. Whether cloud to cloud, cloud to ground, or ground to ground, integration is probably one of the most difficult aspects of any implementation. Integration comes in two flavors:
Back-end integration is the most common. Back-end integration involves integrating data between two systems either for processing or presenting a common user experience.
After three years, I have decided to update my GC cheat sheet.
New version finally includes G1 options, thankfully there are not very many of them. There are also few useful options introduced to CMS including parallel inital mark and initiating concurrent cycles by timer.
Finally, I made separate cheat sheet versions for Java 7 and Java 8.
Below are links to PDF versions
I ran into a situation last week where a developer complained that a query sometimes ran for 3 or more seconds but normally runs much less than 1 second. I had just been to a local AZORA user group meeting where Tim Gorman talked about using ASH to diagnose issues so Tim’s talk motivated me to find some clever way to use ASH. I had these three pairs of start and stop dates and times to (more...)

When using the data modeler, we assume when you add a foreign key, you haven’t already created the ID column.
So we create that for you.
Here’s what that looks like.
I draw the relationship.
It’s creating a new column for me to use for the relationship/FK – I don’t want that.
I don’t... [Read More
This year I get to speak about advanced SQL twice at two different conferences. My first presentation is about row pattern matching with MATCH_RECOGNIZE and my second deals with ranges - including but not limited to Temporal Validity ranges.
Juergen Schuster, who has been enthusiastically trying OraOpenSource Logger, raised an idea for the debug/instrumentation library requesting the addition of a standard synonym “l” for the package. The motive behind this request was to allow our PL/SQL code to remain easy to read, in spite of all the calls to logger sprinkled throughout that are needed for effective debugging and instrumentation.
In the judgement of some (myself included) the addition of the synonym to (more...)
I have been asked a number of times during and after presenting on this topic (SQL Pattern Matching Deep Dive) what is the difference between the various matching options such as EMPTY MATCHES and UNMATCHED ROWS. This is the area that I am going to cover in this particular blog post, which is No 4 in this deep dive... [Read More
Happy anniversary to me!
On this day 10 years ago I published the first article in my blog. It was about the parameter optimizer_index_cost_adj (hence OICA), a parameter that has been a source of many performance problems and baffled DBAs over the years and, if you read my first blog posting, a parameter that should be

In this article, I explain what the different data types are in Oracle database and everything you need to know about them. What You’ll Learn about Oracle SQL Data Types There are many data types in the Oracle database. There are character, number, date, and other data types. When you create a table, you need to […]
Building mobile apps can be as challenging as using a certain 1990s cult workout routine in order to get into shape... that is to say, it can be pretty difficult! IT departments often will be tasked with building and maintaining complex mobile applications, and therefore, other types of apps sometimes are de-prioritized. While widely used consumer-facing apps and upgrades/maintenance to back end infrastructure supporting those apps always will be a priority, simple apps serving useful (more...)

Web-based content in Oracle E-Business Suite 12 runs on the Oracle
Application Framework (OAF or "OA Framework") user
interface libraries and infrastructure. Since the release of Oracle

cumulative Bundle Patches that can be applied on top of the Release
I had an observation come to me last week about PL/SQL and populating nested tables.
“The BULK COLLECT into <nested table> statement cannot be used repeatedly to append results into a table.
Instead, it silently truncates the target table each time. “
This is true. However, if you need to use BULK COLLECT to append results into a single nested table data structure, it is trivial to come up with a workaround using (more...)

I’m mega-fan of the music of the late David Bowie. I love everything he did from Hunky Dory (1971) up to his Lodger (1979) album (you can keep the rest). His so-called Berlin Trilogy is amongst my favorite recordings; I always go to some of his old Berlin haunts whenever I find myself in the Hauptstadt.
Indeed, Berlin is the European city (more...)
