Overview of Application Integration  Transaction Integrator (TI) allows for communication between Windows and mainframe or AS/400 programs using COM or.Net – no need for TCP/IP Sockets or APPC programming  Comprised of three parts – TI Designer – to create a COM typelib or.Net assembly describing the methods and data to be exchanged TI Designer – to create a COM typelib or.Net assembly describing the methods and data to be exchanged TI Manager – to configure the PC and host environments TI Manager – to configure the PC and host environments TI Runtime – installed with TI Manager when installing via HIS 2004 Server Enterprise Edition TI Runtime – installed with TI Manager when installing via HIS 2004 Server Enterprise Edition  Connectivity to mainframe via LU 6.2 or TCP/IP  Connectivity to AS/400 via TCP/IP  Supports two-phase commit over LU 6.2  Comes with a tutorial called CedarBank in the SDK  Tightly integrated with Visual Studio.Net

CedarBank Tutorial  Tutorial is installed with the HIS 2004 SDK  Default location: C:\Program Files\Microsoft Host Integration Server \SDK\Samples\AppInt\HostInitiated C:\Program Files\Microsoft Host Integration Server \SDK\Samples\AppInt\HostInitiated C:\Program Files\Microsoft Host Integration Server \SDK\Samples\AppInt\WindowsInitiated C:\Program Files\Microsoft Host Integration Server \SDK\Samples\AppInt\WindowsInitiated  All CICS and IMS information is included for Windows and for the Mainframe  Sample RPG code is included for the AS/400  For WIP - Cedrbank and GetAccounts methods  For HIP – Cedrbank method

TI Manager

Windows Initiated Processing (WIP)  Client program on Windows initiates call to host program  Mainframe – CICS or IMS - LU 6.2 or TCP/IP  AS/400 – RPG programs – TCP/IP only  Use TI Designer within VS.Net to build a COM type library or a.Net assembly that is called from a client program  TI Runtime uses the typelib or assembly to translate the incoming client data, send the data to the host, and translate the returned host data to send back to the client  TI Manager is an MMC Snap-in used for defining host information such as IP address or LU names

Host Initiated Processing Overview  Client program on host initiates a call to a Windows program  Mainframe – CICS or IMS - LU 6.2 or TCP/IP  AS/400 – RPG programs – TCP/IP only  Use TI Designer within VS.Net to build a COM type library or a.Net assembly  Program a dll that implements the methods exposed in the typelib or assembly  TI Runtime uses the typelib or assembly to translate the incoming host data, send the data to the Windows server program, and translate the returned data to send back to the host  TI Manager sets up a Windows Service that listens for incoming calls from the host
