The maximum number of processes required in the proxy container is as high as the sum of processes required for outbound and inbound communication.
Outbound communication
For outbound communication, the number of processes required of the bean is the number of parallel connections of the bean if the connections are not organized in groups. If the connections are organized in groups, the number of processes required is the number of connection groups used at a time.
In addition, the total number of processes depends on the number of beans using outbound communication at a time and whether this communication is transactional or non-transactional. In the case of transactional communication, a process of the proxy container is exclusively assigned to a bean until the transaction is completed; in the case of non-transactional communication this is done only for the time required for a conversation.
Inbound communication
For inbound communication, the number of required processes is at least as high as the maximum number of parallel inbound messages. The parallel inbound messages can at most be as many as the number of parallel connections to all EIS partners.
