PACLOG for DB2

The architecture of PACLOG for DB2 is centered around several key components designed to efficiently manage DB2 log files. The PACLOG Controller is the central component, responsible for managing and coordinating all operations. It interfaces with DB2 to access log files and interacts with the z/OS operating system for file operations.

The Log Compression Engine is a critical component, utilizing compression algorithms to reduce the size of log files. This engine is configurable, allowing administrators to specify compression levels to balance storage savings and processing overhead. The Archive Manager handles the archiving and retrieval of compressed log files.

This component manages the storage and retrieval of archived logs, ensuring data integrity and accessibility. Communication between these components occurs through the DB2 interface and z/OS system calls. Data storage relies on z/OS file systems for storing both the original and compressed log files.

The configuration file is a central element, defining parameters such as the DB2 subsystem ID, log file locations, compression settings, and archive destinations. The CLI provides the primary interface for administrative tasks, including commands like `COMPRESS`, `ARCHIVE`, and `RETRIEVE`. logcopy1 ARCHIVEDIR=/path/to/archive`.

The tool does not expose any REST or SOAP APIs.
