Summary
This article describes software updates that allow the Host-Initiated Processing Server (HIP) program a lot of delivery issues for client applications running on IBM mainframe machines.


Solution to problem
Cumulative update information
Supported features that change the default Host integration server behavior are now available from Microsoft Support. However, this feature is intended to change only the behavior described in this article. Apply only to systems that specifically need it.

Fixes that resolve this issue are included in cumulative update 2 for Host Server 2013 integration.
Status
Microsoft has confirmed that this is a problem in the Microsoft products listed in the "Applies to" section.
Further information
Features Transaction Integrator Host-Initiated processing enables client applications running on IBM mainframe machines to call the .NET Framework object specified in Windows-based applications. This feature also allows client applications to pass parameters to objects and receive parameters (data) of objects. The original design, the HIP server program sends the received parameters for the IBM host application calls in one send operation.

After you apply this update, the HIP server program can send parameters (data) for client applications on the IBM mainframe machine in multiple send operations. This new functionality applies only when the HIP connects to the IBM mainframe using a communicating SNA endpoint to use the APPC session (LU 6.2).

To support sending some parameters (data) back to the IBM host application call, Host-Initiated server context processing is updated to include the new SendDataDelegate property. The SendDataDelegate server context property accepts objects that are either .NET Strings or objects that are specified as structures in the Integrator XML Definition (HIDX) host file that uses HIS design in Visual Studio. The SendDataDelegate property uses certain .NET Strings or structures to determine what data to send to the client application on the IBM mainframe. Program HIP Server by using the following format to contact SendDataDelegate key:
