Most developers have struggled with wires in SOA composites. You may find yourself in a situation where a wire has been deleted. Some missing wires are restored by JDeveloper. Other missing wires have to be added manually, by simply re-connecting the involved adapters and components. Simple.
Recently, I had a real life situation of missing wires. I had a conduit where there was no longer a wire inside. Normally, there is a wire inside (more...)
The Oracle Service Bus has built in features to poll an IMAP of POP3 mail account. There are loads of excellent blog posts that exactly describe how to do it. However, when the mail server happens to be a Microsoft Exchange server, things become shady. Exchange’s IMAP implementation tends to be not really that compatible, and the server log will fill up with stacktraces such as:
javax.mail.MessagingException: Connect failed;
nested exception is:
What are microservices?
Have you heard of Microservices yet? First time I heard the word I had strong associations with a new appliation for bacterial life in food processing. Maybe my background in biochemistry got the better of me.
Actually, the Microservices Architecture (MSA) is a new sprout on the ever-growing tree of Service-Oriented Architecture concepts. The definition sounds vaguely familiar: A particular method of designing (usually complex) enterprise software applications as suites of small, independent (more...)
The past week my colleague Patrick Sinke and myself attended the Oracle Fusion Middleware Forum 2016 in Valencia, Spain held from March 15th to March 18th. It was a week overloaded with information, networking and deep-dive workshops. We worked hard, learned a lot and had some fun once in a while as well. The event coinciding with the annual Las Fallas festival also helped with that last part
In this blog I would like to (more...)
Hereby a script to change some properties for SOA Suite. These are some generic settings such as:
- Recovery Schedule Config
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 22.214.171.124.0 + BP4 I had issues with migration even after applying patch 18025048. I just applied BP7 and installed the latest 126.96.36.199.0 (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...)
