Fast Index for Db2 Modernization Guide

Fast Index for Db2 accelerates index creation by using a shadow table approach. It creates a temporary shadow table, populates it with indexed data, and then swaps it with the original table. This minimizes disruption to Db2 operations.

Fast Index for Db2 supports various Db2 environments, including single-server and multi-server configurations. It is compatible with different Db2 versions on z/OS.

Yes, Fast Index for Db2 can be used to re-index existing tables. This can help improve query performance and maintain index integrity.

Fast Index for Db2 uses configuration files to define parameters such as shadow table names, storage locations, and other operational settings. These files are typically managed by Db2 administrators.

The core component is the Index Accelerator Engine, which manages the shadow table creation, data population, and table swapping processes. It interacts directly with Db2.

Fast Index for Db2 primarily uses standard Db2 interfaces for communication. It leverages SQL commands and stored procedures to interact with Db2 databases.

Fast Index for Db2 uses Db2's storage mechanisms for storing both the original and shadow tables. This includes Db2-managed datasets and storage groups.

Fast Index for Db2 does not expose external APIs such as REST or SOAP. It operates within the Db2 environment using native interfaces.

The primary configuration interface is through JCL (Job Control Language) and Db2 commands. Parameters are set within JCL jobs that invoke Fast Index for Db2.

By minimizing downtime during index creation, Fast Index for Db2 ensures continuous availability of Db2 applications, leading to improved business operations and reduced revenue loss.

Faster index creation translates to quicker deployment of new applications and enhancements, providing a competitive advantage by enabling faster time-to-market.

By optimizing index creation, Fast Index for Db2 contributes to better query performance, which in turn reduces resource consumption and lowers operational costs.

Fast Index for Db2 helps maintain data integrity by ensuring that indexes are created correctly and efficiently, reducing the risk of data corruption or inconsistencies.

Fast Index for Db2 leverages Db2's built-in security features for authentication. It supports authentication methods configured within the Db2 environment, such as RACF.

Fast Index for Db2 relies on Db2's access control model, which includes role-based access control (RBAC). Permissions are managed through Db2 grants and privileges.

Data encryption is handled by Db2. Fast Index for Db2 does not introduce additional encryption mechanisms but relies on Db2's encryption capabilities for data at rest and in transit.

Fast Index for Db2 logs all operations to the Db2 system logs. These logs can be used for auditing and tracking index creation activities.

Fast Index for Db2 is administered through JCL and Db2 commands. Monitoring is performed using standard Db2 monitoring tools and utilities.

User management is handled through Db2's user management facilities. Fast Index for Db2 does not introduce separate user accounts or management processes.

Key configuration parameters include the names of shadow tables, storage locations, and performance tuning options. These parameters are set in the JCL.

Monitoring is achieved through Db2's built-in monitoring tools, such as the Db2 Performance Expert. These tools provide insights into the performance of index creation processes.
