Let's say you have a virtual machine with two network adapters, both set on 'HostOnly'. I used to do that and set the first one of those to a fixed IP address, say 10.0.0.1. To this one I coupled the hostname, for instance darlin-vce-db, using the /etc/hosts file. That way I had a fixed, always existing network address for the database.
Together with the database, you install WebLogic, for instance to serve (more...)
Unfortunately I noticed this nice initiative only yesterday: OTN Appreciation Day. I did not had a change to cook something up, but I do like to add some mustard after the meal, as we say in Dutch.
In the titles I miss BPEL. In 2004,when Oracle acquired Collaxa, I worked at Oracle Consulting in the Netherlands. Was working with Oracle Workflow and Interconnect. Oracle wasn't yet into SOA really. But with BPEL PM they acquired (more...)
At my current customer I have SQLDeveloper open the whole day, and regularly I come back to it to query my throttle-table to see if my requests have been picked up. But regularly my database connection have been broken because of being idle. Probably because of a nasty firewall between my remote development desktop and the database.
OK, it wasn’t me exactly. It was more like some of my software-based representatives.
Hi, I’m Ed (@edhjones). And I’m not one of the AppsLab folks. But I’m always interested in the work they do, so I try to hang out with them whenever we’re co-located. I was intrigued then when, a couple of months prior to OOW16, I get a mail from Jake (@jkuramot) CC’ing Raymond (@yuhuaxie). It (more...)
To day I had some problems with deploying my composite to the server of my current customer. Apparently the Server had some problems with datasources. But since there are many I did not feel much for checking them one by one with the console. Using Google I got the following examples
This blog will show how to invoke java code directly from within a Business Rules component. I didn’t manage to find this in the Oracle product documentation, which is actually a good thing. Invoking java code with business logic directly from within the Business Rules is normally bad design. The proper way to do it would be to first invoke business rules and then – depending on the outcome – invoke the (more...)
We have been quietly observing and evaluating our options before we finally decided to get a telepresence robot. Telepresence technology dates back to 1993 (Human Productivity Lab) and telepresence robots are not completely new.
There are two ways you can access Oracle NoSQL database from a Node.js application. These are illustrated below. You can use the nosqldb-oraclejs driver and you can use Oracle REST Data Services.
In my previous blog post I illustrated how you can access Oracle NoSQL database by using the nosqldb-oraclejs driver. I encountered an issue when using the NoSQL database version 12R188.8.131.52 with the currently newest available Node.js driver for (more...)
An engaging, interactive set of sessions that brings you the latest in user experience trends, emerging technology insights, startup innovation, and cloud computing hotness from Bucharest and Silicon Valley.
Apache Spark made numerous appearances in many different sessions during Oracle OpenWorld 2016. It is clear that Oracle is very much embracing and leveraging and endorsing Spark at various levels. Apache Spark is “a fast and general engine for large-scale data processing”. Spark has taken over from Hadoop MapReduce as the most prominent distributed job engine that organizes jobs – including sending the function to the distributed data and gathering the results. You can run (more...)
Companies talk about “Gamification,” but the first time I felt like I was playing a game at work was driving our Double telepresence robot around the office floor, rolling down the hallway and poking into cubicles. With a few simple controls—forward, backward, left, and right—it took me back to the D-pad on my NES, trying to maneuver some creature or robot on the screen and avoid obstacles.
Events are quite relevant in modern computer architecture. At various levels of the stack. Events can represent various things – from IoT based measurements and logistical updates to web site activities and business transactions to operational IT metrics and situations. Events can be produced at peak speeds and high volumes – and may require rapid and robust processing. Apache Kafka has grown into almost the de facto foundation for event processing. Apache Kafka provides high (more...)
The Oracle PaaS cloud is turning into the next generation application server platform. More specifically: Oracle has announced the roadmap for the Application Container Cloud Service (not to be confused with the plain Container Cloud Service which runs pre built Docker containers without looking into them). The Application Container Cloud Servic
accepts and runs applications (not containers) implemented in a number of technologies – Node.js, Java SE, PHP, Python, Ruby, Go and Spark/Hadoop (more...)
The next major release of the Oracle Database has always been a big thing. Last year at Oracle OpenWorld , a lot of sessions were dedicated to Release 2 of Oracle Database 12c – with sharding as probably its most eye catching new feature. Talk of the release date started at once. June 2016 was a popular date in these talks. June came and went. And now, come Oracle OpenWorld 2016, R2 is out – (more...)
One of the interesting tidbits, somewhat hidden away in Thomas Kurian’s keynote presentation last week at Oracle OpenWorld 2016, is a new member of the Oracle PaaS Cloud Services family called Oracle Functions (or at least that seems to be the working title). Oracle Functions are serverless applications that are run on the Oracle PaaS infrastructure when one of its triggering events has been published.
The next screenshot shows a function as part of a (more...)
Earlier I wrote about the automatic installation of Fusion Middleware components using response files. A thing that lacked in my scripts was that although I had a FMW_HOME variable set in my enviroment shell script, the response files had the location hard coded in them. At the time I hadn't had the chance to figure out how to do property/variable replacement in shell. I do know how to do it with ANT. But I figured (more...)
Oracle Database Release 12c (12.1) introduced a new operator that we can use in SQL queries. The MATCH_RECOGNIZE operator allows us to detect patterns in our relational data. Specifically: it allows us to identify records that mark the beginning of a set of records that together form a pattern. In this set, each record satisifies a certain condition. The fact that in a set of records these conditions are met – in a certain (more...)
