HCOM Modernization Guide

HCOM facilitates communication between HP NonStop systems and z/OS transaction environments like IMS, CICS, and CA IDMS. It handles data conversion and protocol translation for seamless interaction.

HCOM uses configuration files to define communication parameters, data mappings, and security settings. These files are typically managed through a command-line interface or a configuration utility.

HCOM supports TCP/IP for network communication. It also supports SNA/APPC for legacy environments. Data conversion is handled internally to ensure compatibility between different platforms.

HCOM provides logging capabilities to track message flow, errors, and security events. These logs can be used for auditing and troubleshooting.

HCOM uses a client-server architecture. Key components include the HCOM server on z/OS, the HCOM client on HP NonStop, and configuration repositories. Communication occurs via TCP/IP or SNA/APPC.

HCOM supports APIs for message submission and retrieval. These APIs are typically native APIs specific to the z/OS and HP NonStop environments. Programming languages like COBOL and C are commonly used.

HCOM uses configuration files to define data mappings between HP NonStop and z/OS systems. These mappings specify how data fields are converted and transformed during message exchange.

Common commands include defining communication paths, configuring data mappings, starting and stopping the HCOM server, and monitoring message queues.

HCOM enables integration between HP NonStop applications and z/OS-based systems, allowing businesses to leverage existing investments in both platforms. This integration streamlines business processes and improves data accessibility.

By facilitating communication between different platforms, HCOM reduces the need for manual data transfer and reconciliation, saving time and resources.

HCOM allows organizations to extend the life of legacy applications by integrating them with modern systems. This approach avoids costly and disruptive application replacements.

HCOM supports authentication methods such as user IDs and passwords, as well as integration with external security systems like RACF on z/OS. Encryption is used to protect data in transit.

HCOM uses an access control model based on user roles and permissions. This model allows administrators to control which users have access to specific resources and functions.

HCOM encrypts data using industry-standard encryption algorithms during transmission between HP NonStop and z/OS systems. This encryption protects sensitive data from unauthorized access.

HCOM provides audit logging capabilities to track security-related events, such as login attempts, access violations, and configuration changes. These logs can be used to monitor security and detect potential threats.

HCOM provides administrative interfaces, including a command-line interface (CLI) and configuration files, for managing the system. User management is typically handled through the z/OS security system (e.g., RACF).

Key configuration parameters include communication port numbers, data mapping definitions, security settings, and logging levels. These parameters are typically stored in configuration files.

HCOM provides monitoring capabilities to track system performance, message throughput, and error rates. These metrics can be used to identify and resolve performance bottlenecks.

HCOM generates logs that capture system events, errors, and security-related activities. These logs can be analyzed to troubleshoot problems and monitor system behavior.
