hi Aike,

this has happened to me while the internal hostname of the machine and the hostname use to access the URL are different. is this the case for you ?

to resolve this, you can edit the file parameters.ymlc  in <axon-install-dir>/axonhome/axon-config and change the parameter axon_unison_host

once changed you need to cleanup the cache folder in

<axon-install-dir>/axonhome/axon/app/cache/prod/

rm -Rf *

and restart the cache server

<axon-install-dir>/axonhome/third-party-app/scripts/memcached restart

thank you

Louis-Noel this is a helpful post...I have had the same challenge.

Could you post an example of what this setting should look like.  I have tried to make this change with no change in results.

Thanks for any guidance you can provide.

hi James,

the parameter should look like :

axon_unison_host: http://<hostname>:<port>/unison

also please check if the unison process is running:

ps -edf | grep unison

For anyone who is having issues in Axon 5.2 with the install in particular the error that "Unison Microservice is not available" and have verified that the microservice is running.

This thread was incredibly helpful to find the issue, but while this may be the intent of how things are intended to work, I found that there is another instance of this same file that is located at:

<<Axon Install Directory>>/axonhome/axon/app/config

This is the key to solving this.

The file is parameters.ymlc

It is the same file as in the axon-config directory but this version of the file is read at startup of the microservices...

I am going to log a note with support on this, but hopefully this reference will really help folks out.

The bottom line...if you run the whole install and get this error message, go and change the setting for axon unison host...and things should work for you.

I hope this helps...Louis-Noel thanks for pushing me in the right direction.

Jim
