CREWS Modernization Guide

CREWS is a catalog backup and recovery tool for z/OS. It provides capabilities for catalog backup, restore, forward recovery from SMF records, catalog checkup and reorganization, and master catalog alias synchronization. It helps ensure the integrity and availability of critical catalog data.

CREWS is a tool set designed to manage and protect z/OS catalogs. It provides a range of utilities for backup, recovery, and maintenance, ensuring catalog data integrity and availability.

Organizations that rely on z/OS mainframe systems and require robust catalog management capabilities use CREWS. This includes enterprises in industries such as banking, finance, insurance, and government.

A company should consider using CREWS when they need a reliable solution for backing up, restoring, and maintaining their z/OS catalogs. This is especially important when dealing with large volumes of data and critical business applications.

Alternatives to CREWS include Mainstar Catalog Recovery Plus, Tivoli Advanced Catalog Management, and Catalog Information Manager. These products offer similar catalog management capabilities for z/OS environments.

CREWS runs on the z/OS platform and requires access to SMF records for forward recovery. It operates within an LPAR and integrates with existing z/OS subsystems.

CREWS is deployed on-premise within the z/OS environment. It requires technical expertise to implement and configure, including knowledge of z/OS systems and catalog management.

CREWS enhances the management of z/OS catalogs by providing backup, recovery, and maintenance capabilities. It operates as a standalone product but integrates with existing z/OS infrastructure.

CREWS requires z/OS and access to SMF records. It may also require specific security configurations and access to system datasets.

CREWS ensures business continuity by providing reliable catalog backup and recovery. It minimizes downtime and data loss in the event of a catalog failure, ensuring critical applications remain available.

Without CREWS, organizations face the risk of catalog corruption or loss, leading to application outages and data unavailability. Manual recovery processes are time-consuming and error-prone.

CREWS helps organizations meet compliance requirements by ensuring the integrity and availability of catalog data. It provides audit trails and reporting capabilities to demonstrate compliance with industry regulations.

CREWS supports standard z/OS authentication methods, such as RACF, ACF2, and Top Secret. It integrates with existing security systems to control access to catalog data and functions.

CREWS uses an access control model based on z/OS security systems (RACF, ACF2, Top Secret). It allows administrators to define granular access permissions for users and groups.

CREWS provides audit logging capabilities to track user activity and system events. These logs can be used to monitor security and identify potential threats.

Ongoing operational requirements for CREWS include monitoring catalog backups, performing regular maintenance, and ensuring the system is properly configured. Staff with z/OS experience are needed to manage the product.

CREWS provides a command-line interface (CLI) and potentially a GUI for administration. User management is handled through z/OS security systems (RACF, ACF2, Top Secret).

Common implementation challenges include configuring CREWS to work with existing z/OS security systems, ensuring proper access to SMF records, and scheduling backups to minimize impact on system performance.
