LSD failover

If the failure occurs after the routing table is available on the client, the WLMClient code does not go to the LSD to determine what server to route WLM'able objects. The WLMClient code handles the routing decisions. If the failure occurs before the first client request that retrieves the WLM information, then WLM depends on the LSD request to fail over to another LSD.

The WLM component is dependent on LSD failover because the first request for a client will require going to the LSD to obtain the first direct IOR. In order to support clients that do not have any WLM code running on them, for example z/OS clients, other ORB providers, and C++ CORBA clients, the WLM routing decisions will utilize the LSD.

Performance of clients that run in WebSphere Java ORBs with the WLM client code will not be affected at all. The IORs are manipulated and routed by the WLM client code, so indirect and direct IORs are handled the same.

Clients without the WLM code would only route to the LSD on the first request of each object. The direct IOR will be used by the client until the client either drops the reference to the object or the server becomes unavailable.
