Columbus Z Reflect Modernization Guide

Columbus Z Reflect redirects output intended for VTAM printers to JES spool or other Columbus software. It intercepts print streams based on VTAM LU names and redirects them without application changes.

Columbus Z Reflect uses configuration files to define VTAM LU names and their corresponding redirection targets. These files specify whether output should be sent to JES, another printer, or a Columbus processing module.

No, Columbus Z Reflect operates transparently. Applications continue to send print jobs to VTAM printers as usual. The software intercepts and redirects the output without requiring any modifications to the applications themselves.

Columbus Z Reflect supports various output formats, including line data, SCS, and IPDS. It can convert between these formats as needed during redirection, ensuring compatibility with the target system.

The core components include the VTAM Listener, which intercepts print data; the Redirection Engine, which determines the new destination; and the Output Formatter, which converts the data if necessary. These components communicate via internal APIs and message queues.

Columbus Z Reflect uses configuration files, typically stored as datasets on z/OS, to define redirection rules. These files specify VTAM LU names, target destinations (JES spool, other printers, or Columbus modules), and any required data transformations.

Columbus Z Reflect does not expose external APIs like REST or SOAP. It primarily uses internal APIs for communication between its components. Integration with other systems is typically achieved through JES or by directing output to other Columbus modules that offer API access.

The VTAM Listener operates on standard VTAM ports. The specific ports used depend on the VTAM configuration. Ensure that these ports are open and accessible for Columbus Z Reflect to intercept print data.

By redirecting output to JES spool, Columbus Z Reflect allows for centralized management and archiving of print data. This can reduce the need for physical printers and improve overall efficiency.

Columbus Z Reflect can redirect output to other Columbus software, such as Columbus View, for enhanced viewing, manipulation, and distribution of print data. This integration provides added value by extending the capabilities of the print management system.

Columbus Z Reflect reduces costs by optimizing printer usage, centralizing output management, and enabling electronic archiving. This reduces the need for physical storage and manual handling of printed documents.

Columbus Z Reflect supports authentication via VTAM. Access to configuration files and administrative functions is controlled through z/OS security mechanisms such as RACF, ACF2, or Top Secret.

Columbus Z Reflect uses an access control model based on z/OS security. Permissions to access and modify configuration files are managed through RACF, ACF2, or Top Secret, providing granular control over who can manage redirection rules.

Columbus Z Reflect does not encrypt print data in transit or at rest. Security relies on the underlying VTAM and z/OS security infrastructure. Consider implementing additional encryption measures if sensitive data is being transmitted.

Columbus Z Reflect logs all redirection activity, including VTAM LU names, target destinations, and any errors encountered. These logs can be used for auditing and troubleshooting purposes. The logs are typically written to z/OS system logs.

Columbus Z Reflect is administered through a combination of ISPF panels and z/OS console commands. ISPF panels are used to configure redirection rules, while console commands can be used to start, stop, and monitor the software.

User management is handled through z/OS security. User IDs and permissions are defined using RACF, ACF2, or Top Secret. Columbus Z Reflect leverages these existing security mechanisms to control access to its functions.

Key configuration parameters include VTAM LU names, target destinations (JES spool, other printers, or Columbus modules), data transformation options, and logging levels. These parameters are defined in configuration files.

Columbus Z Reflect provides comprehensive logging capabilities. It logs all redirection activity, including VTAM LU names, target destinations, and any errors encountered. These logs can be used for monitoring system performance and troubleshooting issues.
