Interacting with VTAM applications with OSPI

OSPI provides a means for REXX- or CLIST-based automation procedures to interface with any LU2 (3270) VTAM application that uses full screens to communicate with users.

With OSPI, BMC AMI OpsA has logon capabilities and complete access to any VTAM application’s data stream. In this way, BMC AMI OpsA can interact with the application by analyzing the output data and issuing the VTAM application’s own commands.

By automatically interfacing with critical VTAM applications and simulating a user at a VTAM terminal, OSPI can communicate with various data center software products and decrease the number of physical terminals required.

OSPI includes three components:

• IMFEXEC commands that allow EXECs to communicate with VTAM applications
• Scripting application that automatically generates IMFEXEC command statements by recording your interactions with a terminal
• Debugging facility

These components are described in the following sections:

• OSPI-sessions provides a general overview about how the Scripting application generates OSPI EXECs.
• OSPI-scripting-application provides detailed information about using the Scripting application.
• Terminating-the-application describes how to customize EXECs generated by the Scripting application.
• OSPI-debugging-facilities describes the Debugging facility.
