Retrieve a host service instance ID
You can retrieve a host service instance ID for a 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 that you want to find
-
Create an integer to store the host service instance ID.
int hostServiceInstanceID;
-
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 host service instance that you want to retrieve the ID for
List<ServiceInstanceType> serviceInstances = result.getServiceInstances();
for (ServiceInstanceType itr:serviceInstances)
{
if (itr2 instanceof DispatcherHostServiceInstance)
{
if (itr2.getName().equalsIgnoreCase(instanceName))
{
hostServiceInstanceID =itr2.getServiceId();
break;
}
}
}
