 | IBM DB2 Archive Log Accelerator (formerly DB2 Archive Log Compression Tool) reduces the overhead that is associated with database log management to balance the increases in archive log growth. The tool achieves this using a combination of data striping (for faster log volume through-put) and DFSMS hardware- or software-based log volume compression. The tool maximizes data availability by leveraging DASD storage that contains compressed archive logs. It accelerates DB2 data recovery and archive log offload processing while adding additional security to existing DB2 backup and recovery assets at the core of data availability and reliability strategies.  - Reduces storage and I/O requirements for managing large-volume DB2 archive logs.
- Accelerates DB2 data recovery with Data Facility Storage Management Subsystem (DFSMS) hardware- or software-based compression.
- Adds incremental security to existing DB2 backup and recovery.
- Reduces overhead of managing archive logs and removes barriers to database growth and availability.
- Provides data striping for faster throughput of log volumes and acceleration of archive log offload processing.
- Optimizes DFSMS compression for maximum storage savings by further reducing size of archive logs.
- Offers a hardware compression modeling tool that allows for comparison of compression techniques.
- Provides archive log operations with data access methods that support extended format data sets--this enables archive logs to be compressed and striped using DFSMS and lets you exploit advanced techniques employing:
- DFSMS/MVS Dictionary Building Block compression with sequential and VSAM KSDS compressed format data sets
- DFSMS tailored compression
- direct analysis of DFSMS compressed logs with DB2 Log Analysis Tool without uncompressing logs before analysis
- archive log compression for DB2 databases that are members of data sharing groups
- Helps lower storage costs by enabling the storage of logs on affordable DASD instead of tape.
- Eliminates need for manual intervention after archive logs are defined as extended format data sets.
- Provides more archive log management options in a single, affordable package.
