CA ASM2 Modernization Guide

CA ASM2 automates dataset backup, archive, and recovery on z/OS systems. It manages storage hierarchies and automates migration between storage tiers.

CA ASM2 uses control datasets to store configuration information. The primary interface is through JCL (Job Control Language) and batch processing.

The main components include the ASM2 address space, control datasets, and associated utilities for data movement and management.

CA ASM2 supports standard z/OS security mechanisms, including RACF, ACF2, and Top Secret, for controlling access to datasets and functions.

Common commands include BACKUP to create backups, RESTORE to recover datasets, ARCHIVE to migrate data to archive storage, and RECALL to bring archived data back online. These commands are typically invoked through JCL.

Basic syntax involves specifying the command (e.g., BACKUP), dataset names, and options within a JCL job step. For example: //BACKUPDS JOB ... //STEP1 EXEC PGM=ASM2UTIL //SYSTSIN DD * BACKUP DATASET(‘your.dataset.name’) - OUTDATASET(‘backup.dataset’) /*

CA ASM2 does not expose REST or SOAP APIs. Integration is typically achieved through JCL and batch processing, or through custom programs that interact with CA ASM2 control datasets.

The main components are the ASM2 address space, which manages the archiving and backup processes; control datasets, which store configuration and metadata; and utility programs, which perform the actual data movement.

CA ASM2 helps reduce storage costs by automatically migrating infrequently accessed data to lower-cost storage tiers. It also improves data availability through automated backup and recovery processes.

By automating data management tasks, CA ASM2 reduces the need for manual intervention, freeing up IT staff to focus on other priorities.

CA ASM2 ensures data is protected and recoverable, minimizing the impact of data loss events and supporting business continuity.

CA ASM2 leverages z/OS security features, including RACF, ACF2, and Top Secret, to control access to datasets and functions. It supports granular access control based on user roles and permissions.

CA ASM2 integrates with z/OS security systems to authenticate users and authorize access to datasets and functions. It supports multi-factor authentication methods supported by the underlying z/OS security system.

CA ASM2 provides audit trails of all data management activities, including backups, archives, and restores. These logs can be used for security monitoring and compliance reporting.

CA ASM2 is administered through JCL and batch processing. Configuration parameters are stored in control datasets, which can be updated using standard z/OS utilities.

CA ASM2 provides monitoring capabilities through SMF (System Management Facilities) records and log files. These records can be used to track system performance and identify potential issues.

Regular maintenance tasks include reviewing log files, monitoring storage utilization, and updating configuration parameters as needed. It is also important to ensure that the control datasets are backed up regularly.

Troubleshooting involves reviewing log files and SMF records to identify the root cause of issues. Common problems include insufficient storage space, incorrect configuration parameters, and security violations.
