Examples of com.sun.xml.ws.api.ha.HaInfo

com.sun.xml.ws.api.ha.HaInfo
This class has HA information
This would help a loadbalancer to put the request(in case of a fail-over) on a replica instance that has all the related data. Even if there is no loadbalancer, a backing store could locate the information by directly going to the correct replica instance. This would also help any part of the runtime to know about failover case(and in-turn may invalidate local caches).
To achieve this functionality, it carries two pieces of information:
1. key - Related {@link org.glassfish.ha.store.api.BackingStore} keys canuse this info for their HashableKey impl. First store creates this object, and subsequent related stores use the same key.
2. replicaInstance - where the related info is replicated
This can be accessed from {@link Packet} using {@link Packet#HA_INFO}property by the runtime. This object is created typically
- When a store happens for the first time
- A subsequent inbound transport creates from cookies
- A fail-over request stores the data to a different replica
