Johannesburg

All

It was quite an interesting city. We can see clearly the reminiscent of the Apartheid system. The Apartheid Museum is very interesting and very near a casino and an amusement park – which as a real mine tour inside.

 

 

Pittsburg

All

Went to Pittsburg on the weekend and was quite cool.

The city is on the hills kinda, and a mix of toronto+montreal. From the first, it has the skyscrapers, and from the second it has some European style ~ right in the middle.

I loved the bridges as well.

8 dollars full park.

South Africa Conference – ECRM 2019

All

Intro

Going to this conference in the Wits School of Business was really cool, basically one of the best business schools in Africa.

Johannesburg

It’s a very interesting city, with better infrastructure than most of the capitals of cities in South America. The population is very polite and driving on the left is quite challenging.

Pretoria

Small and cozy city, but very cool. Not that far from Jozy actually, about 50 min, the same as the

Conference

This time was a smaller conference than the one in Austria, but very interesting speeches and discussions. The fact that the conference was small, allowed a better and deeper interaction with the members.

Cape Town

Unfortunately, this will be for the next visit.

People

People there are amazing, the customer service for restaurants and commerce is really great.

Loading jni library

All

I think that’s quite interesting that we need to load the -Djava.library.path and the System.setProperty and why is that?!

  1. Set path in console when executing jar:
    java -Djava.library.path=./lib -jar myApplication.jar
  2. Set path in the code before loading library:
    System.setProperty("java.library.path", "./lib");

On this stackoverflow they discuss about this, it’s for some systems that do not load from the lib call.

Xmx vs MaxRAM

All

That’s quite confusing but Xmx=1g lets my JVM consuming more than 1g of RAM. How so?

Doing some tests here I see that when using Xmx=1g, the JVM is actually using 1.5g! well the explanation is simple:

Xmx only limits the allocated memory on the heap.

So how to limit it??

To specify the total usage you need to use -XX:MaxRAM.

Thanks, CHF for this tip! 

You can use this table as a reference.

EAP Galleon

All

Intro

This a project to make EAP more efficient and smaller specifically for deployment in containers. You basically don’t need the whole EAP with full functionalities, but only the ones you will actually use.

Galleon ~ Cloud native EAP

    Installation

From Git

   Creating an EAP with only the minimal you need ~ using layers:

Just run the command

galleon.sh install wildfly:current --layers=cloud-profile,core-server,core-tools --dir=my-wildfly-server

~ this will create a minimal wildly with cloud-profile, core services, and core tools.

Shift integration

It’s very useful then, to use with Open Shift and provide
