On May 21st, 22nd and 23rd – AMIS and Oracle join forces for a three day event around enterprise application development with Oracle Fusion Middleware. The event targets senior (ADF) developers and application architects. It addresses many of the themes currently or shortly relevant to any organization: multi device UI, mobility, security, agile & automated software engineering, performance & scalability, user experience, web & mobile oriented architecture and cloud. It will discuss and demonstrate Oracle’s (more...)
I got the newly available Kaplan test prep software for the Oracle 12c OCP upgrade exam.
I took the test in certification mode when I was tired at the end of the day some day last week and got 44% right – fail! I usually wait until I get all the questions right before taking the real test so I have a ways to go.
The practice test software has been useful in terms (more...)
Oracle Far Sync is an Oracle 12c new feature for Oracle Data Guard. This feature is meant to resolve the performance problems induced by network latency when you maintain a standby database geographically distant of the primary database. In this type of situation you sometimes have to make a compromise between performance and data loss. [...]
The post Far Sync (Oracle 12c New Feature) appeared first on Oracle DBA Scripts and Articles (Montreal).
I tested this example in Oracle 12.1. First I created a table:
SQL> create table fred
2 as select * from user_synonyms
3 where 1 = 2
Then I checked its object_id for later:
SQL> select object_id
2 from user_objects
3 where object_name = 'FRED'
... and described it:
SQL> desc fred
Back in March of last year I wrote an article on the five frequently misused metrics in Oracle: These Aren’t the Metrics You’re Looking For.
To sum up, my five picks for the most misused metrics were:
- db file scattered read – Scattered reads aren’t always full table scans, and they’re certainly not always bad.
- Parse to Execute Ratio – This is not a metric that shows how often you’re hard parsing, no matter how (more...)

So I am working on a new REST API for an upcoming Oracle cloud service these days so one of the things I needed was the ability to automatically generate a JSON Schema for the bean in my model. I am using MOXy to generate the JSON from POJO and as of version 2.5.1 of EclipseLink
it now has the ability to generate a JSON Schema from the bean model.
There will be (more...)
WordPress 3.8.3 came out yesterday. It’s a small maintenance release, with the downloads and changelog in the usual places. For many people, this update will happen automatically and they’ll just receive and email to say it has been applied.
I’m still not sure what to make of the auto-update feature of WordPress. Part of me likes it and part of me is a bit irritated by it. For the lazy folks out there, (more...)
The Simplified UI design patterns and guidelines for building the Oracle HCM Cloud and Oracle Sales Cloud simplified user interfaces are now available from the Oracle Applications User Experience team as an eBook.
The eBook covers the Oracle ADF-based UX design patterns, page types, and components used to build the SUIs, and now you can build your own cool UIs too.
The book is simple to read, it’s short, and it’s free!
Thanks to a certain recent Open SSL bug there’s been a lot of attention paid to passwords in the media. I’ve been using KeePassX to manage my passwords for the last few years so it’s easy for me to find accounts that I should update. It’s also a good opportunity to use stronger passwords than ‘banana’.
My problem is that I have always resisted the generation function in KeePassX because the resulting strings are very (more...)
ADF BC ViewObjects provide a very valuable mechanism to page through large data sets so that a user can navigate to a specific page in the results. Range Paging fetches and caches only the current page of rows in the ViewObject row cache (at the cost of another query execution) to retrieve each page of data. Range paging is very performing when your ViewObject has access to (hundreds of) thousands of database rows, and if (more...)
I have just posted an answer to a question that seems like a bug in the JasperReportsIntegration toolkit, that you have to use absolute paths for referencing images or subreports, which is typically a bad thing.
Don't know exactly why it doesn't work, but there is a workaround for that: http://www.opal-consulting.de/site/jasperreportsintegration-full-path-requirement-and-workaround/
Hope that helps,
I have been blogging at daust.blogspot.com
for quite some years now ... and many people have rather preferred wordpress to blogspot, I can now understand why :).
It is quite flexible and easy to use and there are tons of themes available ... really cool ones.
The main decision to host my own wordpress instance was in the end motivated by different means. I have created two products and they needed a platform to be (more...)
