26 26  == 4. Failover Deployment Step ==
27 27  
28 -If you want to expand the grouping functionality to include an active/passive failover component, you need to change the settings on the inbound component. Apart from specifying the group name, you need to configure the auto-startup option on "No" so the failover configuration can take the correct actions in all situations.
28 +The configuration of a Failover deployment step is similar as for the Group deployment step. The only difference is the action you can activate. The stop group actions make the inbounds of the currently selected container stop, and consequently, ...

36 -== 3.3 Failover Infra ==
37 -
38 -The configuration of the infra flow of the runtime for which you want to configure the failover is detailed and only works if you configure all support objects correctly. Although we explain the various steps in the documentation, we advise utilizing the store item we created for this that will guide you in setting this up correctly.
39 -
40 -The configuration consists of at least three separate support objects. Two are needed once (infinispan cache manager and clustered lock registry), whereas the other is required per unique group you have defined within the context of your runtime. So, if you have two unique group names within the runtime, you need two leader initiator support objects.

42 -=== 3.3.1 Infinispan Cache Manager ===
43 -
44 -Given this, let us first look at the Infinispan cache manager. You can add this support object in the [[standard manner>>doc:Main.eMagiz Academy.Microlearnings.Crash Course.Crash Course Platform.crashcourse-platform-create-support-objects-introduction||target="blank"]] by searching for "infinispan cache manager."

58 -Now that we have the cache manager, we can configure the next support object on our list, the clustered lock registry. You can add this support object in the [[standard manner>>doc:Main.eMagiz Academy.Microlearnings.Crash Course.Crash Course Platform.crashcourse-platform-create-support-objects-introduction||target="blank"]] by searching for "lock registry."

66 -=== 3.3.3 Leader Initiator ===

68 -Lastly, we need to configure a leader initiator for each **unique** group we have defined within the context of the runtime, and that uses the failover functionality. You can add this support object in the [[standard manner>>doc:Main.eMagiz Academy.Microlearnings.Crash Course.Crash Course Platform.crashcourse-platform-create-support-objects-introduction||target="blank"]] by searching for "leader."
