Error al iniciar segundo nodo de un cluster.

[carlosjl]

Buenos días, he configurado un cluster de 2 nodos con almacenamiento compartido con la versión community 3.4.e según la documentación.
Aparentemente, el cluster está funcionando ya que me conecto a un nodo subo documentación y desde otro navegador conectado al otro nodo veo dicho documento.

Cuando inicio el segundo nodo del cluster obtengo el siguiente error:

ERROR [quartz.core.JobRunShell] Job DEFAULT.org.springframework.scheduling.quartz.JobDetailBean#302609b3 threw an unhandled Exception:

Alguna referencia al respecto.


Un saludo y gracias de antemano.

CarlosJL, no se puede montar un clúster en Alfresco Community. Esa es una de las diferencias entre Alfresco Comunity y Enterprise. Quizás sea por eso tu error. 

Un saludo.

Olá
As tecnoogias responsáveis pelos clusters eram o " Ehcache e JGroups", porém eles foram retiradas após a versão do Alfresco Community  4.0.
