How does CA Data Compressor for DB2 integrate with DB2?

The product integrates directly with DB2 using native interfaces. It intercepts I/O requests to compress data before it is written to disk and decompresses it when it is read. There are no documented APIs exposed for external integration.

What is the architecture of CA Data Compressor for DB2?

The architecture includes a compression engine that uses algorithms to reduce the size of data blocks. This engine interacts with DB2 through a load module, which intercepts data access requests. The compressed data is stored directly within the DB2 tables.

What is the business value of using CA Data Compressor for DB2?

By compressing data, the product reduces the amount of storage space required, leading to cost savings. It also improves I/O performance, as less data needs to be read from and written to disk.

How does the product minimize disruption to existing applications?

The product's transparent operation minimizes disruption to existing applications and DB2 users. Compression and decompression happen automatically, without requiring changes to application code or database queries.

How does CA Data Compressor for DB2 handle security?

The product leverages DB2's existing security mechanisms for authentication and access control. It does not introduce its own security model but relies on DB2's user management and authorization features.

What audit and logging capabilities exist?

The product integrates with DB2's audit logging capabilities to track compression-related activities. These logs can be used to monitor compression ratios, identify potential issues, and ensure compliance with security policies.

What administrative interfaces are available?

The product provides administrative interfaces for configuring compression parameters, monitoring compression ratios, and managing compression rules. These interfaces may include command-line tools and graphical interfaces.

What monitoring capabilities exist?

The product integrates with DB2's monitoring tools to provide insights into compression performance and storage savings. These tools can be used to track compression ratios, identify potential bottlenecks, and optimize compression settings.

Product Overview

CA Data Compressor for DB2's architecture centered around transparent data compression within DB2 databases. The main components included the compression engine, DB2 interface module, and configuration management tools. The compression engine employed algorithms to reduce data block sizes, while the DB2 interface module facilitated interaction with DB2.

Configuration was managed through configuration files, specifying compression rules and parameters. The product integrated directly with DB2 using native interfaces, intercepting I/O requests to compress data before writing to disk. It leveraged DB2's existing security mechanisms for authentication and access control.

Given that CA Data Compressor for DB2 is no longer supported, organizations should consider alternatives such as IBM Db2 Data Compression or BMC AMI Data Compression for Db2. These alternatives offer similar architectural patterns and integration capabilities. When migrating, consider the impact on existing DB2 infrastructure and application compatibility.

Frequently Asked Questions

What is CA Data Compressor for DB2?

CA Data Compressor for DB2 is a data compression tool that operates transparently within the DB2 environment. It reduces storage space and I/O overhead by compressing data at the table level.

What configuration files are used?

The product primarily uses configuration files to define compression rules and parameters. These files specify which tables to compress, the compression algorithms to use, and other settings related to compression behavior.

What are the main system components?

The main system components include the compression engine, the DB2 interface module, and the configuration management tools. The compression engine handles the actual compression and decompression of data. The DB2 interface module allows the compressor to interact with DB2. Configuration tools allow administrators to manage compression settings.
