CA Jars Modernization Guide

CA Jars is a job accounting and resource management system that collects and processes SMF records to provide detailed reports on resource usage. It helps organizations understand how system resources are being used, enabling better capacity planning and cost management.

CA Jars primarily uses SMF (System Management Facilities) records as its data source. It also supports input from other sources, such as user-defined files, to provide a comprehensive view of system resource consumption.

CA Jars provides reports on CPU usage, DASD (Direct Access Storage Device) utilization, print activity, and other system resource consumption metrics. These reports help in identifying resource bottlenecks and optimizing system performance.

CA Jars can be used to track resource usage by department, project, or user, allowing for chargeback accounting. This helps in allocating costs accurately and promoting responsible resource consumption.

Common operations include defining report parameters, scheduling report generation, and analyzing report output. Users often use JCL (Job Control Language) to submit batch jobs for report generation.

CA Jars uses configuration files to define report layouts, data sources, and processing parameters. These files are typically maintained by system administrators.

CA Jars processes SMF records using batch jobs submitted via JCL. The JCL specifies the program to execute (typically a CA Jars-provided utility), the input data sets (SMF records), and the output data sets (reports).

While CA Jars does not expose a standard REST or SOAP API, it can be integrated with other systems through its batch processing capabilities. Reports can be generated and then consumed by other applications.

CA Jars provides detailed insights into resource consumption, enabling organizations to optimize their IT infrastructure and reduce costs. By identifying underutilized resources, organizations can consolidate systems and improve efficiency.

By tracking resource usage by department or project, CA Jars enables accurate chargeback accounting. This promotes responsible resource consumption and ensures that costs are allocated fairly.

CA Jars helps organizations comply with internal and external reporting requirements by providing detailed audit trails of resource usage. This ensures transparency and accountability in IT operations.

CA Jars leverages the security features of the z/OS and zVSE/VSEn operating systems. Access to CA Jars functions and reports is controlled through RACF (Resource Access Control Facility) or similar security systems.

CA Jars integrates with RACF to provide role-based access control (RBAC). Users are assigned roles that determine their access to specific functions and data within CA Jars.

CA Jars provides audit logging capabilities to track user activity and system events. These logs can be used to monitor security and ensure compliance with internal policies.

CA Jars is typically administered through JCL and ISPF panels. System administrators use these interfaces to configure CA Jars, manage users, and schedule reports.

User management in CA Jars is handled through RACF or a similar security system. User access is controlled through roles and permissions defined in RACF.

CA Jars provides monitoring and logging capabilities to track system performance and identify potential issues. These logs can be used to troubleshoot problems and optimize system performance.

Key configuration parameters include report layouts, data sources, processing parameters, and security settings. These parameters are typically defined in configuration files maintained by system administrators.
