Retrieve a host service instance object
You can retrieve a host service instance for any component that can be configured to support high availability. Components that cannot be configured to support high availability have only a service instance.
The following code sample retrieves a
Dispatcher host service instance.
Before you begin: Retrieve the following variables:
- serviceID integer for the service ID that you want to find
a host service instance of
- instanceName string for the name of the host service instance you want to find
-
Create a DispatcherHostServiceInstance
object to store the host service instance.
DispatcherHostServiceInstance hostServiceInstance;
-
Invoke findServiceInstancesByService().
boolean includeStatus=false;
boolean includeExtendedData=true;
boolean loadServiceConsumerRelationships=false;
boolean loadServiceProducerRelationships=false;
FindServiceInstancesByServiceResult result=coreWebService.findServiceInstancesByService(serviceID, locale, includeStatus, includeExtendedData, loadServiceConsumerRelationships, loadServiceProducerRelationships);
-
Check the result for errors and handle any errors.
if (result.getFindServiceInstancesByServiceReturnStatus().getCode()!= FindServiceInstancesByServiceReturnStatusEnumType.SUCCESS)
{
// handle any errors
}
- Loop through the result until you find the dispatcher host service instance object you want to find.
List<ServiceInstanceType> serviceInstances = result.getServiceInstances();
for (ServiceInstanceType itr:serviceInstances)
{
if (itr instanceof DispatcherHostServiceInstance)
{
if (itr.getName().equalsIgnoreCase(instanceName))
{
return itr;
}
}
}
