Maybe I shouldn’t have written about flexible security, because I immediately starting hitting inflexible security, locking me out.
Today’s fail is courtesy of MailChimp.com, which I use for my newsletters. It’s OK that they decided they want a confirmation when I log on to my account from India, but it is not OK that they require a text message passcode with no other option.
I have my phone in flight mode, because I don’t (more...)
View Criteria is set to execute in Database mode by default. There is option to change execution mode to Both. This would execute query and fetch results from database and from memory. Such query execution is useful, when we want to include newly created (but not commited yet) row into View Criteria result. Newly created row will be included into View Criteria resultset.
Somedays you come across some code and think that's pretty, why didn't I think of that? So my long time colleague Mark Warner has a nice twist on the standard name/value store pattern using method references to deal with converting from a String.
I've been heads-down in writing my next O'Reilly report and didn't had enough time to blog in a while. Time to catch up here and give you a real quick start into the new microservices framework named Lagom. It is different to what you might know from Java EE or other application frameworks. And this is both a challenge and opportunity for you to learn something new. If you can wait for a couple of (more...)
I almost always use the tomcat buildpack within IBM Bluemix for my Java based applications. By default IBM bluemix will use the IBM Liberty buildpack for java apps unless you specify otherwise. The buildpacks on Bluemix can be viewed using "cf buildpacks" and the tomcat buildpack is referred to as "java_buildpack"
So to use the tomcat buildpack in a manifest.yml you would target it as follows
Each time when data is changed and updated through ADF BC, before posting changes to DB, SQL query with FOR UPDATE NOWAIT is generated and executed. In case if other process locks row to be updated, or another user in the same moment is updating it, error will be generated and update will be stopped. There might be use cases, when you would like to wait for certain period of time, until row will be (more...)
The need to gain actionable insights from ever increasing data sets is a huge problem for BI professionals. Attend our webinar presented by Numenta, a machine intelligence company founded by Jeff Hawkins (the founder of Palm Inc.), and learn how machine intelligence can help you solve real world enterprise IT problems.
Watch the short video about Numenta's story and the importance of their approach to machine learning:
One of the common use cases in enteprise applications is to track concurrent user changes. There are two types of changes possible - when two real users are changing data in the same row, or when single user is changing data and same row is updated by PL/SQL procedure/function (all happen in the same user session). In the first case, we would like to inform a user - row data was changed (two different users (more...)
Working with and talking about microservices has been my focus for a while already. And since I started working at Lightbend I already had the pleasure to work with some amazing people. One of them is Jonas Bonér and it has been a real pleasure helping with the creation of this little mini book about reactive microservices. Many of the concepts described in this book are the foundation for our newly open source microservices framework Lagom. It makes (more...)
In this blog article I explain what happens with mappings for which the source is empty, and you map it to an optional or mandatory element. The scenarios described in this article are based on SOA / BPEL 11g. In some next article I will describe what happens when you do the same in SOA 12c (which is not the same).
We've got a webinar tomorrow. Attend our webinar and learn how you can monitor your Oracle Database instances with the open source monitoring tool Zabbix. Sign up at this link.More than 125 people have already signed up!
- Hello Developer. - Hello... you.. - Listen, I have this great idea for an App. - Really? - yeah! - what's it about? - can't tell you. - OK... - So Developer, will you write the code for the App? - OK, but what should I write? What will the App do? - Cant tell you. - Why? - You haven't signed a NDA yet. - I see. so where is it? - I (more...)
When you work on larger JDeveloper/ADF 12c project, most likely you will experience issues with application redeployment (rerun). These two issues will be encountered:
1. It doesnt work anymore (it worked on 11g) to simply rerun application (applies for 12.1.3 and 12.2.1), without stopping it and then running again. In most of the cases if you try to rerun application, some strange errors are returned or changes are not visible at (more...)
Do you want to test in your environment REST service running on Oracle MCS cloud? I have implemented public REST service hosted on Oracle MCS, you can call it from Postman application (Google Chrome extension).
Implemented use case - SOAP Connector in MCS is reading Stock Quote information for the company supplied in the request. Information is transformed by MCS Custom API (with Node.js) into REST structure and returned to the client through MCS (more...)
Sample application used for the demo, can be downloaded from here (it consists of three parts - WebSocker server implementation, ADF BC tester application to generate continuos DB updates and JET application) - Oracle JET Live List with WebSocket.
ADF application with live data DVT component (more...)
7 and 8 March iAdvise was present as Diamond Sponsor at Apex World. For the first time it was a two day event. Because of the success last year, the location of Apex World was again the beautiful SS Rotterdam. Over the past few years, the event became more and more international. This was clearly seen in the language of the presentations. Nearly all the presentations were held in English.
Picture this at will. You come back from work all tired and happy of your great productive day and all you want is to order your favourite pizza. You will have to either call them and probably wait for somebody to answer the phone or you will be put on a queue, or, you will go on-line and place your order. Hang on a minute.. You will (more...)
Attend our free webinar and learn how you can use Zabbix, the open source monitoring solution, to monitor your Oracle Database instances? The webinar is presented by Oracle ACE and Certified Master Ronald Rood.
About the Webinar:
Enterprise IT is moving to the Cloud. With tens, hundreds even thousands of servers in the Cloud, monitoring the uptime, performance and quality of the Cloud infrastructure becomes a challenge that traditional monitoring tools struggle to solve. Enter (more...)
