Exceptions when Overriding Cluster Policies
In addition to handling the exceptions that may occur when sending a JMS message, a service that overrides a cluster policy must handle ISRuntimeExceptions that result when policy requirements are not or cannot be met. Integration Server throws an ISRuntimeException after attempting to override a policy for the following general reasons:
The service sending the JMS message provided invalid data and the
Broker Server throws an exception.
Integration Server wraps the
Broker Server exception and rethrows it as an ISRuntimeException.
The
Brokers specified in the
JMS_WMClusterNodes input parameter are not available.
Following is a list of situations in which Integration Server throws an ISRuntimeException while attempting to override the connection factory policy when sending a JMS message.
The
JMS_WMClusterNodes specifies a single
Broker and that
Broker is not available. This applies to policies such as round robin, round robin weighted, random, and sticky.
The
JMS_WMClusterNodes specifies multiple
Brokers and the policy requires that the JMS message be sent to one
Broker. This applies to the round robin, round robin weighted, random, and sticky policies.
The cluster policy is multisend best effort and none of the
Brokers specified in
JMS_WMClusterNodes are available.
The cluster policy is multisend guaranteed and one or more of the
Brokers specified in
JMS_WMClusterNodes are not available.
The
JMS_WMClusterNodes specifies a
Broker that is no longer part of the
Broker cluster for the cluster connection factory.
