ClearPath Application Integration Services Product

Product Overview

The process of developing a distributed application leveraging resources from multiple operating environments presents a unique set of organizational and technical challenges. Examples range from skills availability for the various operating environments to dealing with different data formats.

The Unisys ClearPath Application Integration Services product is designed to make it easier for you to develop distributed applications.

This product

  • Helps you reduce the cost of developing distributed applications.

    This product provides APIs that applications running in one operating environment can use to access resources such as files or applications in another operating environment. For example, a Windows application can access COMS transactions or read MCP files. ClearPath Application Integration Services has been designed to reduce the amount of code that developers have to design, write, and test.

  • Is optimized for specific operating environments.

    This product provides the Unisys value-added capabilities that standards-based products such as Client Access Services cannot provide. For example, it can enable a Windows application to access the attributes of an MCP file.

  • Leverages the ClearPath Forward high-speed interconnect.

    When a distributed application using ClearPath Application Integration Services is deployed on a fabric-enabled ClearPath Forward server, it can take advantage of the high-speed interconnect between the Microsoft Windows and ClearPath MCP Environments within the ClearPath Forward server.

  • Provides transparent application deployment flexibility.

    Using ClearPath Application Integration Services, you have the flexibility to deploy distributed applications on fabric-enabled ClearPath Forward servers, on other ClearPath servers as well as on Windows servers and PCs. When the high-speed interconnect is not available, TCP/IP networking is used for the connection.

General Features

The ClearPath Application Integration Services product provides a set of application programming interfaces (APIs) that enable Windows-based applications to access MCP-based files, integrate MCP-based libraries, and initiate COMs transactions in the ClearPath MCP Environment.

  • File access APIs enable applications running in the Microsoft .NET Framework to create, access, and update files in the ClearPath MCP Environment.

    • The Windows API enables applications running in the Microsoft .NET Framework to access MCP files in a manner that is similar to the way they access Windows files using the .NET System.IO API.

    • The MCP API enables applications running in the Microsoft .NET Framework to use record-oriented access to MCP files. It supports fixed-length and variable-length records and file streams. Applications can also access MCP file attributes.

    Both APIs support various MCP-coded character sets

  • Application integration APIs enable applications running in the Microsoft .NET Framework to call libraries in the ClearPath MCP Environment. The APIs support libraries written in COBOL85, ALGOL, and NEWP languages.

  • Transaction Integration APIs enable Windows-based applications to initiate transactions in the ClearPath MCP Environment under the control of the COMS Transaction Server.

  • Application Integration Services uses the security modules of the MCP to authenticate users and log them into a ClearPath MCP server.

  • Application Integration Services provides APIs that enable Java applications running on Microsoft Windows to access MCP-based files, use the Java Native Interface (JNI) to integrate with MCP-based applications, login to a ClearPath MCP server, and call the MCP time function.

    • File access APIs enable Java applications to create, access, and update record-oriented files in the ClearPath MCP Environment

    • JNI enables integration of Java applications running on Microsoft Windows with ClearPath MCP-based applications.

    • Java applications can call libraries running in the MCP Environment. Libraries written in ALGOL are supported.

    • ClearPath MCP-based applications can call Java applications. The MCP-based applications can be written in either COBOL85 or ALGOL.

    • MCP security APIs enable Java applications to have users authenticated by the security modules of the MCP and to login to a ClearPath MCP server.

    • The MCP time function API enables Java applications to call the MCP time functions to obtain various ClearPath MCP system times and system attributes. This is the same MCP time function that is available to ALGOL applications.
