TWSeasy Modernization Guide

TWSeasy is a set of tools and utilities designed to enhance the functionality of Tivoli Workload Scheduler (TWS) on z/OS. It provides capabilities for database management, application definition, job scheduling, and JCL simulation with variable substitution. The tools aim to simplify and automate TWS-related tasks.

TWSeasy is a tool set designed to extend and simplify the use of Tivoli Workload Scheduler. It provides utilities for managing the TWS database, defining applications, scheduling jobs, and simulating JCL with TWS variables. It is not a standalone system or application, but rather a collection of tools that enhance an existing TWS environment.

Organizations that rely on Tivoli Workload Scheduler for batch processing and job scheduling on z/OS mainframes are the typical users. This includes enterprises in industries such as banking, finance, insurance, and retail that require robust and automated workload management.

A company should consider using TWSeasy when they need to streamline TWS database management, simplify application definition and job scheduling, or improve the accuracy of JCL execution through variable simulation. It is particularly useful when dealing with mass changes or deletions in the TWS database.

Alternatives to TWSeasy include other TWS enhancement tools or custom-developed scripts and utilities. Some organizations may also consider upgrading to newer workload automation platforms that offer similar functionality. Specific competing products include VISUALjob EPD, Rocket OpsCentral, and Workload Planner.

TWSeasy requires an existing Tivoli Workload Scheduler (TWS) environment running on z/OS. It leverages TWS infrastructure and databases. It also requires access to z/OS datasets and JCL libraries.

Yes, TWSeasy is z/OS dependent and runs within an LPAR on a mainframe system. It interacts directly with z/OS datasets and requires access to TWS subsystems.

TWSeasy extends the functionality of Tivoli Workload Scheduler (TWS) by providing tools for database management, application definition, and JCL simulation. It enhances TWS capabilities and simplifies common tasks.

TWSeasy simplifies TWS database management by providing tools to load and unload the database to/from sequential datasets, enabling mass changes and deletions. It also streamlines application definition and job scheduling processes. The JCL simulation feature helps to reduce errors and improve job execution.

Without TWSeasy, organizations may face challenges in efficiently managing the TWS database, defining applications, and scheduling jobs. Mass changes and deletions in the TWS database may become cumbersome and error-prone. JCL errors may lead to job failures and delays.

TWSeasy leverages the security features of z/OS and Tivoli Workload Scheduler. Access to TWSeasy functions and data is controlled through z/OS security mechanisms, such as RACF or ACF2. Specific authentication methods depend on the z/OS security configuration.

TWSeasy integrates with z/OS security systems like RACF or ACF2 to control access to its functions and data. The access control model is typically based on assigning users or groups to specific roles or permissions within the z/OS environment.

TWSeasy is typically deployed on-premise, within the z/OS environment where Tivoli Workload Scheduler is running. It requires technical expertise in z/OS, TWS, and JCL. Ongoing operational requirements include monitoring job execution, maintaining the TWS database, and applying updates to TWSeasy.

Implementing TWSeasy requires expertise in z/OS, Tivoli Workload Scheduler, and JCL. Common challenges include configuring TWSeasy to work with the existing TWS environment, ensuring proper security settings, and training users on the new tools and utilities.

Ongoing operational requirements for TWSeasy include monitoring job execution, maintaining the TWS database, applying updates to TWSeasy, and providing user support. Regular backups of the TWS database are also essential.
