Oracle OTN Tour 2017 Sao Paulo: Getting Started with Java Cloud Service (JCS)

At the 2017 OTN stop in Sao Paulo I did my first presentation to help customers to get started with Oracle Java Cloud Service (JCS).

 There are  actually a few showstoppers that make customer’s experience more difficult than it should be in my opinion. I will blog about them later in autumn – for now please have a look at my presentation on Slideshare.

 

Cloud, Microservices and Container Workshop in South Africa!

Lot’s of people are talking about these topics nowadays. Heaps of slides and samples are available for download, lots of presentations can simply be streamed from youtube.

In Johannesburg we were working with these solutions hands-on: I delivered a 3 day Cloud, Microservices and Containers workshop on behalf of Oracle.

Find attached some impressions from the smart and fun group of devs and architects I was working with.

 

 

WebLogic 12c Zero Downtime Director’s Cut: What you missed …

Everything has limitations. And 2 Minute Tech Tips are 2 minutes only. Strict rules. Anyway, you missed a lot of the good stuff that I recorded in Manly Australia, i.e. the introduction of the 2 minute tech tip about Zero Downtime (ZDT):
Why I was standing on Manly Beach, the wildlife story about sharks that stopped me from having a bath, furthermore some whales (real whales! – not a Docker whale this time) and all the crazy things that happened while we recorded.

So here is the introduction. Enjoy.

OSB / SOA Suite 12c Domain Types

OSB / SOA Suite 12c Domain Types

screen-shot-2016-11-30-at-16-22-10Let me explain you some news about the domain types in 12c, since some of my colleagues were fiddling around with this. Due to the new quickstart installer for SOA Suite and OSB 12c there are more domain types available now for SOA Suite and OSB12c that you need to understand. The following options describe those types with added comments of when the make sense.

 

 

Options:

  1. The integrated domain that gets generated by JDeveloper if you run a project. Sometimes it is called default domain. This domain is bound to JDeveloper. Whenever you quit JDev, the domain shuts down. The downside is that this domain always supports OSB and SOA Suite, so a bit of waste of resources if you are only after OSB . This is the easiest solution for your first steps because no manual domain creation is required and JDev does it all for you.
  2. A standalone domain. This is the new and interesting option, because a standalone domain uses the Java DB and does not require you to run the RCU utility. Still a standalone domain is running independent from JDeveloper 12c, so you could you use this type of domain for development with OSB web console.You create the domain by setting the QS_TEMPLATES environment variable and running qs_config.sh, then create an application server connection with JDev, use the standalone server option in the application server connection wizzard, and point it to the standalone domain.
    You will be able to use “Deploy” from JDeveloper, but unfortunately not “Run as”.
    There are more benefits to a standalone domain not mentioned in the official documentation: Whereas the integrated domain includes everything needed for SOA suite you can restrict a standalone domain to Service Bus only and therefore reduce the number of internal deployments from 304 to 278 which will save you startup time.
  3. A compact domain can be used with quickstart. Also compact domains are targeted for development. This domain will be compatible with add-ons such at MFT, OES, etc. Note that you have to specify a special parameter CONFIG_JVM_ARGS=-Dcom.oracle.cie.config.showProfile for this option to be visible in the configuration wizzard.
    Since you can use it with an compatible Oracle DB, the necessary schemas have to be created with the RCU utility. Note: A compact domain is a developer domain consisting of a single admin server and no managed servers.
    The opposite of a compact domain is called extended domain where resources are deployed on a cluster of managed servers. Use extended domain for environments such as test, integration, load test, prod. These environments are distributed and clustered typically due to HA requirements.

Conclusion

It is important to understand the various domain types and to choose the correct domain type for your requirements. You can strip down a standalone domain to be OSB only, then make sure to select Integrated Servers if you want to deploy directly from JDev to it.

OTN Tour Latin America 2016: Chile

Oracle Technology Network Tour Latam 2016:
Santiago de Chile

The conference in Chile was exceptional for a couple of reasons. For the first time ever I met German, the tech reviewer of my WebLogic 12c book. A great guy (not sure if he wants to read his name here – just get the book, he is in the acknowledgement!) who did a brilliant job in editing the 12c book. We had lunch together with his friends from Oracle ACS and the best I can say it felt like friends you know for years and not somebody you met 30 minutes ago. It was a pleasure meeting you guys!

Conference

The conference itself was the University San Sebastian in Bellavista area. Quite a few presentations were running in several rooms in parallel.

Also Santiago is great. From every traffic jam you can see the mountains! It is really a pity I couldn’t go to any more remote places like Atacama desert or Torre de Paine. Anyway both are now top on my to-travel list. My friends know what this means. Stay tuned.

Again I did a Docker live demo. The audience seemed to like it, what do you think? Also the room was big enough for big ideas. Big thank you to CLOUG and Felipe Manriquez.

The non Conference Part

I did not really have a lot of time for sightseeing but I managed to nip out and have a seafood lunch at the Mercado Central before heading to airport. Actually a memorable drive, since the Uber driver was driving alongside the runway but was not able to find the airport 🙂
