This parameter will help to give more priority to the service which is running on two nodes
As we know ,2 instance of esb_dt of oc4j can not run at the same time.
so inorder to implement HA on esb_dt we use this parameter .
In the below example we will give service-weight as 100 for node 1 and service-weight as 75 to node 2
So at any point of time we node 1 is down then only node 2 est_dt will start .
Node 1
Node 2
Service failover is mechanism to specify a critical process that must be run somewhere in an Oracle Application Server cluster if service is disrupted on a processing server. This enables you to preferentially select which processes must be kept running.
Any process-type opmn.xml file element may be configured as a service fail-over such that, once started, OPMN will ensure that the configured number of processes for the service are running on Oracle Application Server instances somewhere in the cluster.
You can configure which Oracle Application Server instances will participate in the service fail-over on an instance by instance basis. You can configure each instance for preferential selection of running the process on available instances.
Only one process-set may be defined for each process-type configured as a service fail-over. Only one process will be run for each service fail-over instance.
Note: You should restart the servies after making any changes to opmn.xml
