Runtime Processing for PCF Command Services
The following diagram illustrates how the PCF Command service executes a PCF command.
Step
Description
1
A flow or Java service, typically invoked by an Integration Server client, initiates the PCF Command service on Integration Server.
You configure the PCF Command service, and the wrapping flow or Java service, using Designer.
2
The PCF Command service retrieves a connection from the service's associated connection pool.
You configure and enable the adapter connection using Integration Server Administrator. For more information about connection pooling, including the runtime behavior of connection pools, see Connection Pools.
3
WebSphere MQ Adapter uses the input parameters of the PCF Command service to generate a PCF command and posts the request to the queue manager using the WebSphere MQ PCF Library.
The following diagram illustrates the PCF Command service's input signature, or input document:

The Queue Manager executes the requested PCF command and returns the response to the adapter.
The PCF Command service returns a message to Integration Server that contains output signature properties. You define the PCF Command service's output signature when you configure the service. The fields that you select on the Response Parameters tab become the service's output signature.
The reasonCode, conditionCode, and errorMsg properties are also returned in the output signature's document.
