4 -eMagiz flows, or more specifically, the flows' inbound components, can be grouped. The benefit from this is that you can later in [[Deploy>>doc:Main.eMagiz Academy.Microlearnings.Intermediate Level.Grouping and Failover.intermediate-grouping-and-failover-deploy-possibilities.WebHome||target="blank"]], control them as one entity. This is mainly beneficial when faced with substantial maintenance or outage of systems connected to your eMagiz model.

6 -Building on this functionality, you can even configure the group to run in an active/passive failover mode when you activate the multiple runtimes option on your runtime, and each separate runtime is deployed on another machine. The failover functionality is not only relevant in cases of server maintenance. It can also assist you when you want to exchange data with a system that allows only one active connection. Should this connection be business-critical, you can use this failover functionality to create a passive failover situation that will take over when the active connection breaks down (regardless of the reason).
3 +eMagiz runtimes can run on local, on-premises servers. Main reason is that some systems are only accessible from within the client's infrastructure. In such scenario's that on-premises server needs to be equipped with a linux based Docker installation.

8 -Setting up this failover functionality in your model requires you to first execute some steps in your Design, Create, and lastly Deploy phase. In this microlearning, we will focus on configuring your setup in the Design phase if you want to activate the active/passive failover configuration.

18 -This microlearning describes how to configure (parts of) of your Design phase to enable failover for systems connecting with your model. The grouping and failover functionality is relevant when faced with maintenance and outages of systems connected to your model. The failover functionality assists in that case and allows you to have a fallback option on an active connection.
13 +This microlearning describes how the eMagiz Deploy agent is installed on the on-premises server where a eMagiz runtime should run on. Please note that the eMagiz Deploy agent requires a valid Docker installation on the on-premises server. The detailed install guide can be found on

24 -To configure failover for systems that are connecting with your model, we first need to go to the Design phase. In your Design>Solution Design, find and open the details of the system that you want to enable failover for. Once you do that, then you need to make sure that "Multiple runtimes" option is selected for this system, which is logical since we want to have a second runtime running in case of failover situations (e.g., outage, maintenance, etc.). Once you do that, you will see the "Number of runtimes" and "Run in failover" fields. To enable failover, make sure that you fill in 2 as the "Number of runtimes", before selecting the "Run in failover" checkbox. See the screenshot below as an example.

21 +eMagiz needs to install a specific agent in the Docker instance that allows to download runtime images that needs to be installed on the Docker instance. The specific command to run inside the Docker instance is specific for the machine that is configured inside eMagiz Design & Deploy Architectures. It can be found inside the eMagiz iPaaS portal under Deploy Architecture. At the runtime connector, there is a right click option called Deploy Agent. That presents either the command or the location where that agent is installed.

34 34  
35 -* Grouping is beneficial when external systems go through maintenance or downtime.
36 -* Failover can have the additional benefit of having a fallback scenario while still adhering to the requirement that there can only be one active connection at a time.
37 -* The role naming in both grouping and failover is crucial. The whole name needs to be matched fully to make it work.
38 -* For the infra configuration of the failover setup, we have a store item that you can use.
29 +* The karaf.log can be found within the folder called log under the folder data
30 +* You can search the log with the help of tools such as Notepad++
31 +* By looking at the timestamp in the eMagiz Manage Log, you can run a focused search
