I'm trying to run a 6 node Apache Artemis static cluster as 3 live-backup pairs. In order not to lose data during full cluster restart I've also created a mechanism figuring out which of the pair has newer data, and based on that the server automatically decides whether it's safe to start that particular node. During full cluster restart the servers are started simultaneously, and nodes with newer data start before nodes that were lately acting as backups.

This scenario has been working flawlessly with single live-backup pair.

Shutdown:

1. Master node is live, slave node is backup
2. Master node => slave node goes live
3. Slave node

Start:

1. Both nodes are dead
2. Slave node => goes live
3. Master node => goes live, slave node goes backup

However in the 6 node cluster the backup node does not go live at all:

1. 3 live nodes, 3 backup nodes; pairs bound together in separate groups (rs1, rs2, rs3)
2. Stop rs1 master node => rs1 slave node goes live
3. Stop rs1 slave node
4. Start rs1 slave node => never goes live
5. Must not start rs1 master node because of potential data loss

Any idea what's wrong with my setup?

I downloaded the zip from https://activemq.apache.org/components/artemis/download/ and unzipped it. Then I ran

After struggling with Artemis 2.11 and an older Java version I decided to update my whole system to the "latest greatest software" that is currently available. So I am using Artemis 2.14 and Java 14.0.2 on two Ubuntu 18.04 VM with 4 Cores an 16 GB RAM.

I configured the master-slave ha-policy like this:

I have just install a new artemis in my new server, able to run the service normally but not able to access from outside.

I also have followed this question that seems have the similar issue with me, but seems not able to work.

I am trying to use UploadObjectExample.java code to upload a file to OCI object storage. I am running into connection timeout error while connecting to the object storage URL. The same config file is used by OCI CLI to successfully upload files to OCI config.

Here is the Error log:

I am creating a react component where I need to show hide a dom element depending on a props. Below you will find a basic idea of the problem. The code is simplified off course.

So, either I am asking incorrectly, or it isn't possible, let's see which...

If my app (Xamarin.Forms) is launched from another app, in order to get a url from my app, how do I return that data to the calling app? I wrongly assumed SetResult and Finish, I also wrongly assumed StartActivityForResult, but there has to be a way to do this. I know how to get data INTO my app from another app, but not the same in return.

POSSIBLE PARTIAL SOLUTION -- UPDATE, FAILS

So I have to setup an interface in my PCL, and call the method from the listview item selected handler, in the Android app I can then do this:
