IWS/Graph Modernization Guide

IWS/Graph visualizes IBM Workload Scheduler configurations as graphs on Microsoft Windows workstations. It provides a graphical representation of schedules and applications, making it easier to understand dependencies and workflows.

IWS/Graph is an application that enhances the usability of IBM Workload Scheduler. It provides a graphical interface to visualize and manage batch schedules and application dependencies.

Organizations that use IBM Workload Scheduler on z/OS and need a visual representation of their schedules and application dependencies benefit from IWS/Graph. These organizations are often in industries such as banking, finance, insurance, and retail.

Consider IWS/Graph when you need a graphical view of your IBM Workload Scheduler environment to simplify understanding and management of complex schedules and application workflows. It is especially useful when troubleshooting or optimizing batch processing.

Alternatives to IWS/Graph include other workload automation visualization tools or custom scripting to extract and display schedule information. However, these alternatives may not offer the same level of integration with IBM Workload Scheduler or the same ease of use.

IWS/Graph requires IBM Workload Scheduler running on z/OS. It also needs a Microsoft Windows workstation to run the graphical interface. Communication between the workstation and the z/OS system is necessary.

IWS/Graph runs on a Microsoft Windows workstation and connects to IBM Workload Scheduler on z/OS. The z/OS component typically runs within an LPAR and relies on z/OS subsystems for communication and data access.

IWS/Graph enhances IBM Workload Scheduler by providing a graphical view of its configurations. It does not replace or duplicate the core scheduling functionality but rather provides a more user-friendly interface for managing and monitoring workloads.

The main components include the IWS/Graph client on the Windows workstation and the communication interface to the IBM Workload Scheduler server on z/OS. The client retrieves data from the server and displays it graphically.

IWS/Graph simplifies the management of complex IBM Workload Scheduler environments by providing a visual representation of schedules and dependencies. This can lead to improved efficiency, reduced errors, and faster problem resolution.

By providing a clear graphical view of workload dependencies, IWS/Graph helps organizations optimize their batch processing and reduce the risk of delays or failures. This can lead to improved service levels and reduced operational costs.

IWS/Graph helps reduce the learning curve for new users of IBM Workload Scheduler by providing a more intuitive interface. This allows them to quickly understand and manage complex schedules, reducing the need for extensive training.

IWS/Graph leverages the security features of IBM Workload Scheduler and z/OS. Access to scheduling information is controlled through the existing security mechanisms of these systems.

Authentication is handled by IBM Workload Scheduler and z/OS. IWS/Graph uses the existing authentication mechanisms to verify user identities before granting access to scheduling data.

Access control is managed through the Role-Based Access Control (RBAC) model in IBM Workload Scheduler. Users are assigned roles that determine their level of access to scheduling objects and functions.

IWS/Graph requires ongoing monitoring to ensure that the connection to IBM Workload Scheduler is maintained and that the graphical interface is functioning correctly. Regular maintenance may be needed to apply updates or fix any issues.

Implementing IWS/Graph typically requires technical expertise in both IBM Workload Scheduler and Microsoft Windows environments. Familiarity with z/OS security concepts is also beneficial.

Common implementation challenges include configuring the communication between the Windows workstation and the z/OS system, ensuring proper security settings, and customizing the graphical display to meet specific user needs.
