Allow sharing of connections between JMS and container-managed persistence (CMP) entity beans.
This option enables container-managed persistence (CMP) entity beans to share the database connections used by the data store of a messaging engine. This has been estimated as a potential performance improvement of 15% for overall message throughput, but can only be used for entity beans connected to the application server that contains the messaging engine.

The name of the inbound transport chain that the application should target when connecting to a messaging engine in a separate process to the application. If a messaging engine in another process is chosen, a connection can be made only if the messaging engine is in a server that runs the specified inbound transport chain. Refer to the InfoCenter for more information.
If the selected messaging engine is in the same server as the application, a direct in-process connection is made and this transport chain property is ignored.
The transport chains represent network protocol stacks operating within a server. The name you specify must be one of the transport chains available in the server that hosts the messaging engine, as listed on the server_name panel. The following transport chains are provided, but you can define your own transport chains on that panel.
