Hi Kathees, Have you started the worker nodes? By theory, Tasks are running on worker nodes. You need to have at least 1 worker node to start executing the tasks. Also there is another configuration file which controls the minimum number of instances to start executing the tasks. This can be configured in the *ESB_HOME/repository/conf/etc/tasks-config.xml* file with the below parameter.
<taskServerCount>2</taskServerCount> The value of 2 means that cluster will wait until 2 worker nodes are started for the execution of tasks.
