Frequently Asked Questions
General
What does CA Compress Data Compression for DB2 do?
CA Compress Data Compression for DB2 transparently compresses DB2 table data. It automatically compresses data when written to disk and decompresses it when read, without requiring changes to DB2 applications or configurations.
Is this a system, application, or tool?
This is a system-level product that enhances DB2's storage capabilities. It operates as middleware, intercepting and processing data as it is written to and read from disk.
What types of organizations use this?
Organizations that manage large DB2 databases on z/OS and need to reduce storage costs or improve I/O performance are ideal candidates. This includes enterprises in banking, finance, insurance, and other data-intensive industries.
When should we consider CA Compress Data Compression for DB2?
Consider CA Compress Data Compression for DB2 when your DB2 database is growing rapidly, storage costs are increasing, or I/O bottlenecks are affecting application performance. It is also useful when needing to comply with data retention policies without expanding physical storage.
What are the alternatives to CA Compress Data Compression for DB2?
Alternatives include DB2's built-in compression features, other third-party compression tools, and hardware-based compression solutions. However, CA Compress Data Compression for DB2 offers transparent operation and potentially higher compression ratios.

undefined
What is the business value of using CA Compress Data Compression for DB2?
The product reduces storage costs by compressing DB2 data, allowing more data to be stored in the same physical space. It can also improve I/O performance by reducing the amount of data that needs to be read from or written to disk. This leads to cost savings, faster application response times, and better resource utilization.
Security
How does CA Compress Data Compression for DB2 integrate with existing security measures?
CA Compress Data Compression for DB2 leverages the security features of z/OS and DB2. It does not introduce new authentication mechanisms but relies on existing DB2 access controls.
What access control model is used?
The product uses the existing DB2 access control model. Access to compressed data is governed by the same privileges and permissions that apply to uncompressed data.
What encryption is used and where?
Data is compressed and decompressed transparently, using algorithms designed to minimize overhead while maximizing compression ratios. The specific algorithms used may vary.
Operations
What ongoing operational requirements exist?
Ongoing operations include monitoring compression ratios, disk space utilization, and I/O performance. Regular maintenance involves applying patches and updates provided by Broadcom.
What monitoring/logging capabilities exist?
The product provides logging capabilities that track compression and decompression activities. These logs can be used for auditing and troubleshooting.
What administrative interfaces are available?
Administrative interfaces are typically command-line based, reflecting the z/OS environment. Configuration files are used to define compression settings for specific DB2 objects.
