ACI Host Link is a set of programs that interfaces CICS® host applications to BASE24 on an IBM Mainframe computer. The solution expedites project implementation, minimizes impact to host applications and eliminates reprogramming of the IBM CICS.
In addition to the standard terminal control management provided by CICS online communication systems, ACI Host Link manages the communications link between the host and the BASE24 processor.
Streamline Workflow
ACI Host Link is a comprehensive product designed to address an institution’s CICS host application and BASE24 interfacing needs. The system can be configured to meet specific requirements, allowing CICS programmers to work on other projects.
ACI Host Link processes all network management messages, eliminating the need to route them to a host application program and reducing the need to issue commands to check status and performance of the communications link between the CICS host application and BASE24.
Easily Configure and Update Systems
ACI Host Link features a table-driven set of processing parameters for ease of initial configuration, permitting timely, online changes to the operating environment. Since these processing parameters are memory resident, the need for disk I/O is virtually nonexistent.
The ACI Advantage
ACI Host Link is compatible with IBM servers operating MVS™ with IBM z/OS™, OS/390® or VSE/ESA™. The solution also is compatible with all core BASE24 solutions, such as BASE24-atm® and BASE24-pos®.
Issuer and Acquirer Host Support
ACI Host Link passes transaction messages sent from BASE24 to issuer host applications for processing and return of a response message. Issuer hosts can specify message reformatting routines in ACI Host Link’s message processing parameters and configure the system to route messages for BASE24 products to specific host applications based upon message routing criteria. ACI Host Link provides CICS acquirer host reformatting and routing support for BASE24 messages, including BASE24-atm and BASE24-pos ISO messages. A transaction request message generated by a CICS host application is passed to the BASE24 host interface module for authorization or force-post response message.
Test and Trace Support Facilities
ACI Host Link’s application testing can begin immediately, without installation of BASE24 software or access to test devices. Test messages are entered into a preformatted input screen and passed to CICS host applications for processing based on defined message routing and reformatting criteria. The host response is delivered to ACI Host Link and displayed on a formatted for review and verification. An internal trace facility incorporated throughout ACI Host Link allows application programmers to capture information at strategic points within the system to aid in resolution of problems on a test system. ACI Host Link’s trace program saves variable transaction information, including BASE24 messages and other relevant data, to the “Trace Data File.” It then records the date, CICS task number and message-specific data required by the requesting program.
