Today the official program is online for DOAG conference 2014 in Nuremberg. My presentation is confirmed “The Dirty Dozen – ADF Migration to 12c in the IKB”.
I will speak over our experiences with following
- provide user software
- install servers
- iterative test migrations
- migration plannig
- real migration
- and the problems and pitfall’s we find on our way
If you speak german and you are interested in some of this, you should come and attend my (more...)
This year at the Kscope conference we started hearing more and more customers saying they were migrating away from Oracle Forms. Many had not started planning or even thought about what such a project entails but the declarations were loud and clear: “We are migrating our Forms system to ______<plug in development tool of choice… ADF…Java…HTML…Net>”. It was as if they were following some trend of what they thought they were supposed to be saying but no one (more...)
Yesterday the Anti-Kyte (a.k.a. Mike) published a great post on coding styles
. I started to post a comment but ended up rambling to I thought I'd put my thoughts here.
I can't be one to comment on tangential intros (just look at any of my presentations), but he almost lost me when I thought the entire post was going to be soccer jokes I didn't get but switched in time to three controversial (more...)
The Lean Startup: How Today’s Entrepreneurs Use Continuous Innovation to Create Radically Successful Businesses by Eric Ries
My rating: 4 of 5 stars
This main point of this book is the principle of “failing fast.” Since you don’t know everything (and a startup knows very little), it is most efficient to quickly create some data to base decisions on.
The distinction between “vanity metrics” and real, useful metrics is illuminating. A “vanity metric” shows (more...)
I’ve been following the discussion on the new In-Memory option in the Oracle 188.8.131.52.0 database. As far as I can see, it’s very easy for a developer to start using this feature, which will cost your company $23,000 per CPU at the next Oracle license audit.
But the most interesting part is actually not the cost – it’s the discussion. Oracle expert Kevin Closson stated that there was a problem (more...)
PyOhio gave my lightning talk on ddlgenerator a warm reception, and Brandon Lorenz got me thinking, and PyOhio sprints filled my with py-drenaline, and now ddlgenerator can inspect your data and spit out SQLAlchemy model definitions for you:
$ cat merovingians.yaml
name: Clovis I
name: Childebert I
$ ddlgenerator --inserts sqlalchemy merovingians.yaml
from sqlalchemy import create_engine, Column, Integer, Table, Unicode
There seems to me to be a relatively simple choice.
Either you except that the Oracle Optimizer has a wealth of complicated strategies and, in this complex effort to get the best executions it can, will inevitably either get it wrong sometimes (or take some extra executions to realise it’s wrong).
Or you stick your head in the sand and raise a bug for every unexpected poor execution or plan flip.
But let’s say that (more...)
APEX 5 is currently in Early Adaptor 2, so the exact implementation of this blogpost might change when APEX 5 goes GA.Font Awesome
is standard included with APEX 5 and you can use the icons on buttons, there is a special property for that.
I was playing around the other day and I wanted to include some Font Awesome icons in my report.
First create a report (classic or interactive, whatever you want) and (more...)
I fielded a question from blog reader on a three year old post about the EOMONTH (End Of Month) function in Excel. The reader want to write a mega-function (a term for putting two or more functions together to solve a problem, according to Mr. Excel). The function would return the first day of any month for the first day of the month and the first day of the next month for any day (more...)
One of the great things about working in IT is that you can often win an argument simply by being right. Not because of who you are or because you are more eloquent than others, but because the facts support your position. Almost every IT person I have ever met respects facts.
In order to win arguments this way, you of course need some facts to work with. And that’s where too many people fail. (more...)
In the projects I've been involved with I've rarely seen it used, but there is a ninth argument in the f?p= syntax
that toggles Printer Friendly
mode.Side note - being the space geek I am this reminded me of the hubhub over Pluto being the ninth planet.
The APEX documentation on Printer Friendly mode states
When referenced, the Application Express engine does not display tabs or navigation bars, and all items are displayed (more...)
How time flies, last March I explained how to install and configure PostgreSQL on Windows. It was my intent to start posting more content on PostgreSQL but I was distracted by another writing commitment on Oracle Database 12c PL/SQL Advanced Programming Techniques, which should be available in November. It tempted me away from PostgreSQL because I got to write about how to use Java inside Oracle Database 12c, which was fun. Having (more...)
After much anticipation the new Release 1 of Oracle 12c (184.108.40.206) is finally available! Get it here: http://www.oracle.com/technetwork/database/enterprise-edition/overview/index.html What does this mean: Oracle’s ground breaking In Memory Database is now available! As they say…this is BIG. Get more details about In Memory here: http://www.oracle.com/technetwork/database/in-memory/overview/index.html I am very excited about the possibilities of what we can […]
The ability to deploy Java inside the Oracle database led somebody to conclude that the source isn’t visible in the data catalog. Then, that person found that they were wrong because the Java source is visible when you use a DDL command to
COMPILE the Java source. This post discloses how to find the Java source and how to prevent it from being stored in the data catalog.
For example, (more...)
