Release : 17.3

Component : SDM - xFlow


This is DE62230: when the domain-name has underscore(_) collabMS service starts and then crashes. Please open a Support case to obtain a new jar file and then do the following

1. make a back up copy of the original file in  xFlow-install-folder \APPS\Services\collabmicroservice-17.0.479\lib . this backup copy should NOT be the same location.

2. shutdown xFlow service

3. download and drop the new file in 

   xFlow-install-folder \APPS\Services\collabmicroservice-17.0.479\lib

  xFlow-install-folder \APPS\Services\searchmicroservice-17.0.479\lib

  xFlow-install-folder \APPS\Services\pushmicroservice-17.0.479\lib

  xFlow-install-folder \APPS\Services\insightmicroservice-17.1.706\lib

  xFlow-install-folder \APPS\Services\incidentmicroservice-17.0.479\lib

(note: total five copy and paste/replace)

4. go to SDM -> Administration -> xFlow Interface -> General -> Collaboration_MicroService_akka.cluster.seed-nodes.0 and check the value. If the value is using fully qualified domain name change it to use hostname. To be specific change, akka.tcp://[email protected]-name:2554 to akka.tcp://[email protected]:2554.

Repeat it for other microservices like Incident (Incident_MicroService_akka.cluster.seed-nodes.0) and Search (Search_MicroService_akka.cluster.seed-nodes.0). 

5. Restart the services
