In this blog posting I explain some changes you need to apply to get instance migration to work for the Oracle BPM 11g Suite.
While figuring out a couple things about instance migrations I have been doing a few Bundle Patch installations lately. Up to 126.96.36.199.0 + BP4 I had issues with migration even after applying patch 18025048. I just applied BP7 and installed the latest 188.8.131.52.0 (more...)
In Oracle Business Rules one can use so-called "Bucketsets". I never liked the term as it is not in the dictionary (did you mean bucketseat?
), and never understood what is wrong with "list of values" (LoV) as that is what it is.
See for example the following bucketset that defines a list of values to be used for some status field:
Anyway, bucketsets are typically used in decision tables to define the set (more...)
I've been doing a bit recently around DevOps and what I've been seeing is that companies that having been scaling DevOps tend to run into a problem: exactly what is a good boundary for a DevOps team? Now I've talked before about how Microservices are just SOA with a new logo, well there is an interesting piece about DevOps as well, its not actually a brand new thing. Its an evolution and
Recently I was pointed to the so-called Oracle Learning Streams http://education.oracle.com/streams
which provide short presentations on all kind of topics.
While ironing my clothes on a Sunday afternoon, I watched one with the title "Leveraging OBPM vs BPEL" by David Mills. An excellent story where he explains in less than 13 minutes the high-level difference using a practical example.
One reason why I like about this stream is that it is in line (more...)
When you want to create a 12.1.3 SOA Suite, Service Bus Domain, you have to use the WebLogic config.sh utility. The 12.1.3 config utility is a big improvement when you compare this to WebLogic 11g. With this I can create some complex cluster configuration without any after configuration.
But if you want to automate the domain creation and use it in your own (provisioning) tool/script then you
One of the new capabilities of Oracle SOA Suite 12c
is the ability to control the SOA infrastructure thread pools, except the resource pools for EDN and the adapters, with Oracle WebLogic Server work managers. Each partition will has its own work managers defined. This allows you to separate services in partitions and, to some extent, tune them separately based on for example specific SLA requirements.
Well, this blog posting is not about explaining the (more...)
With the 12.1.3 release of Oracle Service Bus and Oracle SOA Suite we finally can build all our soa projects with Maven. And this time we can do it natively without calling a utility like configjar or ANT from Maven .
We start by setting all the required variables like JAVA_HOME,M2_HOME and PATH
There is a massive amount of IT hype that is focused on what people see, its about the agile delivery of interfaces, about reporting, visualisation and interactional models. If you could weight hype then it is quite clear that 95% of all IT is about this area. Its why we need development teams working hand-in-hand with the business, its why animations and visualisation are massively important.
Microservices is a Service Oriented Delivery approach, all within a Service Oriented Architecture context.
(Long Title ;)
Ok so a few more updates since the last time I wrote about Microservices and I think its worth just updating as it really is heavily underlining why Microservices is a Service Oriented Delivery approach that absolutely can fit within a Service Oriented Architecture. Lets be
Ok so its started a bit of debate on Twitter and now there have been emails, but in the spirit of openness I thought I'd better blog. Now its good that Martin has now added a side bar on SOA to his article on Microservices but that really makes it worse in many ways. I'll get to that at the end but first off lets explain why Microservices is just another SOA implementation pattern. Its SOD
Hat tip to John Evedemon for the heads up on this one. Martin Fowler is peddling a new approach, 'Microservices' which... wait for it is a way of developing applications as a suite of services. Each one of which has its own process thread and 'communicates via lightweight mechanisms' such as.... over HTTP.
But wait there is more, you'll be stunned to know that these services can be built
In our middleware solutions (Oracle SOA Suite) we use a lot of xsl transformations.
Part of these transformations use database backend systems to do lookups for transforming internal values to external values (which can then be communicated to the customers).
In the Oracle SOA Suite you can create custom xsl function and store the jar in the domain/lib folder and then you will be able to use it in the xsl transformations.
We use Altova (more...)
WebLogic 10.3.6 comes with Jersey1.9 and has no support for Server Side Events or WebSockets. But for one of our projects we are making a HTML5 / AngularJS application, which need to invoke some RESTful services and we also want to use of SSE or WebSockets.
Off course we can use WebLogic 12.1.2 but we already have an OSB / SOA Suite WebLogic 10.3.6 environment.
So when you want to pimp your
