CONVERSE from NetView

A CONVERSE request from a NetView command list (or command processor) starts a CICS® transaction on the same host. The CICS transaction is expected to return a response to a specified NetView task in a named NetView domain.

The response can have the form of a RESPONSE, an ACK, or a NACK.

EVESNCCI returns a message and a return code indicating whether the command was successful or not. If the command is accepted, it is forwarded to the EVENTASK optional task.

The EVENTASK optional task uses the program-to-program interface to notify CICS that the transaction is to be started.

The started transaction retrieves the input data. The CICS transaction returns a response to NetView. The response is sent back to the EVENTASK optional task using the program-to-program interface. The processing of the response sent to NetView differs for the various response types, as follows:
A for ACK
The following message is sent to the requestor: 
EVE128I POSITIVE ACKNOWLEDGEMENT
N for NACK
The following message is sent to the requestor: 
EVE129E response_data
Where response_data is the data that is returned by the CICS program.
R for RESPONSE
When this request type is used, the NetView program-to-program interface initialization member is interrogated to locate the function requested so that the command list can be identified. The request is then scheduled under the autotask associated with the requested function, after which the data is sent to the requestor.
Figure 1 illustrates the flow of events initiated by an EVESNCCI CONVERSE request.

Notes:
  1. Parameters passed with EVESNCCI indicate the request type (in this case C for CONVERSE), the target CICS, the name of the function to be invoked, data (if required), and the requesting operator ID and domain ID.
  2. The responses (RESPONSE, ACK, or NACK) are returned from CICS to the requestor (operator ID and domain ID).
  3. The function name is used to locate the transaction name in the CICS initialization member. If the transaction name cannot be found, a NACK response is returned.
