CA ASTEX Modernization Guide

CA ASTEX is a storage performance manager that analyzes and recommends dataset placement to optimize performance. It includes components for storage, cache, and DASD management.

CA ASTEX is a tool set designed to improve storage performance on z/OS systems. It provides recommendations for dataset placement and cache optimization.

Organizations that rely on z/OS mainframe systems and require optimized storage performance would benefit from CA ASTEX. This includes enterprises in banking, finance, insurance, and other industries with large data processing needs.

A company should consider CA ASTEX when they experience storage performance bottlenecks on their z/OS systems, or when they want to proactively optimize storage utilization and improve application response times.

Alternatives to CA ASTEX include other storage management tools for z/OS, such as IBM's DFSMSrmm, or BMC's MainView Storage Manager. These products offer similar functionality for managing and optimizing storage resources.

CA ASTEX runs on z/OS mainframe systems. It is z/OS dependent and likely runs within an LPAR. It may require specific z/OS subsystems for data collection and analysis.

CA ASTEX requires a z/OS environment with DASD storage. It likely uses VSAM datasets or other z/OS-specific storage mechanisms to store its configuration and performance data.

CA ASTEX likely uses a combination of batch jobs and online monitors to collect and analyze storage performance data. It may use SMF records as a primary data source.

The exact API details for CA ASTEX are not readily available, but it likely exposes APIs or interfaces for data extraction and integration with other monitoring or reporting tools. These APIs may be based on standard protocols like TCP/IP.

CA ASTEX helps organizations improve storage efficiency, reduce I/O bottlenecks, and optimize application performance. By providing recommendations for dataset placement and cache management, it can lead to cost savings and improved service levels.

Without CA ASTEX, organizations may experience suboptimal storage performance, leading to slower application response times, increased I/O contention, and higher storage costs. Manual analysis of storage performance data can be time-consuming and less effective.

CA ASTEX integrates with existing z/OS infrastructure and storage management systems. It complements other tools for performance monitoring, capacity planning, and workload management.

Security features in CA ASTEX likely include access controls to restrict who can view or modify storage management configurations. It may integrate with z/OS security systems like RACF, ACF2, or Top Secret for authentication and authorization.

CA ASTEX likely uses an access control model based on roles or groups, where users are assigned to roles that grant specific permissions to access storage management functions and data.

CA ASTEX likely maintains audit logs of user activity and configuration changes. These logs can be used to track who made changes to storage configurations and when.

Deploying CA ASTEX typically involves installing the software on a z/OS system, configuring it to collect storage performance data, and defining policies for dataset placement and cache management.

Implementing CA ASTEX requires expertise in z/OS storage management, performance tuning, and system configuration. Familiarity with DASD devices, caching algorithms, and storage management concepts is essential.

Ongoing operational requirements for CA ASTEX include monitoring storage performance, reviewing recommendations for dataset placement, and adjusting configurations as needed to maintain optimal performance. Regular maintenance and updates are also required.

Common implementation challenges include integrating CA ASTEX with existing storage management systems, configuring it to accurately reflect the storage environment, and ensuring that recommendations are aligned with business requirements.
