IMS Connect send-only with error protocol enhancement

In IMS 15.4, IMS Connect clients can use the new send-only with error protocol to send transactions and receive errors that occur in IMS Connect.

When users use the existing send-only protocol, IMS Connect does not return any error response to the client. By using the send-only with error protocol, clients could receive responses for errors that occur in IMS Connect while maintaining the high throughput of the send-only protocol.

Note that IMS Connect does not return error messages from the IMS system. The IMS Connect send-only with error protocol returns only error messages from IMS Connect client back to the client.

This enhancement is delivered with APAR PH41890/PTF UI81659.
