Datacom Modernization Guide

Datacom is a relational database management system (RDBMS) designed for high-volume transaction processing and data management on z/OS and zVSE/VSEn platforms.

Optional components include Presspack for database compression and FastRestore to improve database forward recovery speed.

Datacom/AD is a restricted version of Datacom/DB used internally by some Broadcom (formerly CA Technologies) products.

Common operations include: connecting to the database, executing SQL queries (SELECT, INSERT, UPDATE, DELETE), managing tables and indexes, and performing backup and recovery operations. Specific syntax depends on the interface used (e.g., Datacom SQL, embedded SQL).

Datacom exposes a native API for COBOL, Assembler, and other languages. It also supports standard interfaces like JDBC and ODBC for integration with Java and other platforms. Communication protocols include TCP/IP and SNA.

Main components include the Datacom/DB database engine, the Datacom/CICS interface, and the Datacom/IDEAL application development environment. These components communicate through internal interfaces and standard protocols like TCP/IP.

Datacom uses its own proprietary storage mechanism optimized for z/OS and zVSE/VSEn environments. It supports various access methods and data organization techniques.

Datacom provides a robust and scalable database platform for mission-critical applications, enabling efficient data management and transaction processing. Its optional components like Presspack and FastRestore can further enhance performance and availability.

Datacom's architecture is optimized for mainframe environments, providing high performance and reliability for demanding workloads. It offers features like data compression and fast recovery to minimize downtime and improve resource utilization.

Datacom supports authentication methods such as RACF (Resource Access Control Facility), ACF2, and Top Secret. It uses an access control model based on roles and permissions, allowing administrators to define granular access privileges for users and groups.

Datacom provides encryption capabilities to protect sensitive data at rest and in transit. It also offers audit logging features to track user activity and system events, enabling security monitoring and compliance reporting.

Datacom provides administrative interfaces through a command-line interface (CLI) and a web-based console. User management is handled through security systems like RACF, ACF2, or Top Secret. Key configuration parameters include database size, buffer pool settings, and security options.

Datacom offers monitoring and logging capabilities through system logs and performance monitoring tools. These tools provide insights into database activity, resource utilization, and potential issues.
