wildfly mixed domain

[mofou2]

Good Morning,

I had a wildfly domain mode with version 10.1.0 with a Host Controller 10.1.0. I upgrade domain controller to version 13 with jboss-server-migration. I want to have a slave with version 10.1.0. When I start wildfly host controller slave 10.1.0,  I have the following message:

[Host Controller] 12:31:38,145 ERROR [org.jboss.as.controller.management-operation] (Host Controller Service Threads - 5) WFLYCTL0013: Operation ("add") failed - address: ([("host-exclude" => "WildFly12.0")]) - failure description:

Could you help me?

Thanks, Greetings

Hi,

I'm not sure what exacly migration tool does, but from the error it seems to me, that you try to start WildFly 10.1 with configuration for WildFly 13.

Currently, I have a domain controller with two host controllers in version 10.1. Now I want a DC with version 13 and a HC1 with version 13 and another HC with version 10.1. This way I could execute applications in instances of wildfly that works with version 10.1. It's possible?. According to the Wildfly version 13 documentation:

WildFly supports "mixed domains" where a later version Domain Controller can manage slaves running previous versions. But those "legacy" slaves can not understand configuration resources, attributes and operations introduced in newer versions. So any attempt to use newer things in the domain wide configuration will fail unless the legacy slaves are ignoring the relevant resources. But ignoring resources will allow the legacy slaves to work fine managing servers using profiles without new concepts, while other hosts can run servers with profiles that take advantage of the latest features.

With the tool jboss migration tool 1.2.0, I uploaded the version of the DC to version 13. The DC starts me but when I join the HC version 10.1 I get the log message that I put up. Any ideas?

Is there an example of a configuration or site where you can see a configuration of wildfly mixed domains?

Thanks

hey,

mixed domain mode is bit of a beast to configure, but in short

- domain controller (DC) must be the latest between all host controllers (HC)

- you need to create profiles that target different versions of HC, so that such profile only contains configuration what was valid at that target version

- usually only EAP versions are supported as target legacy version, as mixed-domain testing and transformers require lots of work

for your case i think you should use target version of EAP 7.0 (WildFly 10.1) or EAP 7.1 (WildFly 11).

Following your summary,

- I have uploaded the DC version from 10.1 to 11 with:

./jboss-server-migration.sh --source ../wildfly-10.1.0.Final --target ../wildfly-11.0.0.Final

- Therefore, it would have a Domain Controller with version 11 but with the profile of the 10. I converted all the configuration file domain.xml less the profile I want to use in HC 10.1.

- I start the DC and all is OK

- When I start the HC 10.1 that already had failed to join the DC with error message:

[Host Controller] 13:34:52,696 ERROR [org.jboss.as.controller.management-operation] (Host Controller Service Threads - 5) WFLYCTL0013: Operation ("add") failed - address: ([("host-exclude" => "WildFly10.1")]) - failure description:

It seems like it does not recognize the Host Controller version. Would I miss some configuration in the host.xml or domain.xml?

Is it possible to run Wildfly profile 10.1 on Wildfly 11?

I'm stuck.

Thank you so much
