PLP202 - Pathway Administration
This course is designed for individuals who will be required to configure, manage, or administer Pathway environments on the Tandem system, or for anyone who needs to understand Pathway operations and the various configuration parameters affecting its operation.

This course does not cover Pathway analysis and tuning using statistics or other system tools, nor does it cover management of application environments using Pathway/XM.

Course Duration: 3 days (on-site)

Anyone who will be required to configure, manage, or administer Pathway environments on the Tandem system, or who needs to understand Pathway operations and the various parameters affecting its operation.


  • Develop an understanding of how Pathway is implemented in a Tandem environment, and the typical sequence of online transactions
  • Learn how to configure a basic Pathway environment, including global and object-specific parameters
  • Learn the methods used for starting, stopping, and restarting a Pathway environment and individual objects within the Pathway, and tips for streamlining these procedures
  • Understand how to obtain information about the Pathway environment and individual objects within the Pathway, as well as how to capture changes made to the Pathway environment for recovery purposes
  • Learn how to use SCUP to obtain information from the Screen COBOL library, to maintain the library, and move items from one environment to another
  • Learn how external Pathway communications can affect Pathway configurations, and special parameters used for these situations
  • Learn some of the considerations necessary when preparing an efficient Pathway configuration, as well as issues that affect its performance
  • Understand the typical methods used for determining if errors exist, and how to diagnose and resolve different kinds of Pathway errors


  • Any of the Introduction to Tandem classes (PLI201, PLI202, PLI203, or PLI204)
  • 6 months of Pathway programming or operations experience
