Fast Recover for Db2 Modernization Guide

Fast Recover for Db2 accelerates the recovery of Db2 tablespaces and indexes by using image copies. It reduces downtime and improves availability.

Fast Recover can recover individual tablespaces or indexes, or perform a full database recovery. It uses parallel processing to speed up the recovery process.

Fast Recover uses Db2 image copies as its primary source for recovery data. It can also integrate with other backup solutions.

Fast Recover supports various Db2 environments, including single-system and data sharing environments. It is designed to work with Db2 on z/OS.

The core command is typically invoked through JCL (Job Control Language) on z/OS. The JCL specifies the tablespaces or indexes to recover, the image copies to use, and various recovery options.

Fast Recover uses configuration parameters specified in the JCL or in separate control cards. These parameters control aspects such as the number of parallel tasks, buffer sizes, and error handling options.

Fast Recover does not expose public APIs like REST or SOAP. It primarily operates through JCL and control cards.

Fast Recover communicates with Db2 using standard Db2 interfaces and protocols. It reads image copies directly from disk or tape storage.

Fast Recover reduces downtime during recovery operations, leading to improved application availability and reduced business impact. Faster recovery times translate to less disruption for users and business processes.

By speeding up recovery, Fast Recover helps organizations meet their recovery time objectives (RTOs). This ensures that critical systems can be brought back online quickly in the event of a failure.

Fast Recover can reduce the costs associated with downtime by minimizing the duration of outages. This includes reduced revenue loss, improved productivity, and lower operational expenses.

Fast Recover leverages the security features of the z/OS operating system and Db2 database. It relies on RACF (Resource Access Control Facility) or similar security systems for authentication and authorization.

Fast Recover uses the access control mechanisms provided by Db2 to control access to tablespaces and indexes during recovery operations. This ensures that only authorized users can initiate or manage recovery processes.

Fast Recover does not directly encrypt data. However, it supports the use of encrypted image copies if Db2 is configured to encrypt backups. The encryption is handled by Db2.

Fast Recover provides logging and auditing capabilities to track recovery operations. These logs can be used to monitor recovery processes, troubleshoot issues, and ensure compliance with security policies.

Fast Recover is administered through JCL and control cards. There is no dedicated GUI or web console. Monitoring is typically done through z/OS system logs and Db2 monitoring tools.

User management is handled through z/OS security systems such as RACF. Fast Recover relies on these systems for authentication and authorization.

Key configuration parameters include the number of parallel tasks, buffer sizes, and error handling options. These parameters are specified in the JCL or control cards.

Fast Recover provides logging information in the z/OS system logs. This information can be used to monitor the progress of recovery operations and troubleshoot any issues.
