WebSphere Enterprise Service Bus for z/OS, Version 6.2.0 Operating Systems: z/OS


Export bindings

To completely quiesce a system, we must consider the different types of request invocations supported by the available Export bindings.

SCA invocation pattern

The following tables represents the type of SCA invocation pattern used for the different Export bindings.

Table 1. EIS export binding and associated invocation patterns
Export binding Operation type Performance attributes and interaction style Invocation style
EIS one-way Asynchronous asynchronous (default)
  Synchronous synchronous
request-response any value synchronous
Table 2. Export bindings and associated operation types and invocation styles
Export binding Operation type Invocation style
EIS one-way OR request-response synchronous
MQ or MQ JMS one-way asynchronous
SCA JMS

one-way

request-response

asynchronous

asynchronous with callback

Web services (soap/http) or (soap/jms)

one-way OR request-response

synchronous

Depending on the application and the topology used, a variety of techniques maybe used to quiesce synchronous communication. It is strongly recommended that the project create a quiescing strategy based on the unique characteristics of the export used and the topology.
