CICS Online Transmission Time Optimizer Modernization Guide

CICS Online Transmission Time Optimizer reduces network traffic by compressing 3270 data streams. It optimizes data transmission between CICS regions and terminals, leading to improved response times and reduced bandwidth consumption. The product integrates with existing CICS environments without requiring application changes.

The product uses a combination of data compression algorithms tailored for 3270 data streams. These algorithms identify and eliminate redundant data, reducing the overall size of the transmitted data. The compression and decompression processes are transparent to the application.

No application changes are typically required. The product integrates with CICS through configuration settings and system parameters. It intercepts and processes 3270 data streams without modifying application code.

The product supports various CICS environments running on z/OS. It is designed to be compatible with standard CICS configurations and network setups.

The main system components include the compression engine, the decompression engine, and the configuration manager. The compression engine compresses data before transmission, while the decompression engine decompresses data upon receipt. The configuration manager allows administrators to define compression rules and settings.

The components communicate through standard CICS intercommunication facilities. The compression and decompression engines are invoked as part of the CICS transaction processing flow. Configuration settings are typically stored in CICS system definition files (CSD).

The product uses CICS system definition files (CSD) for storing configuration parameters. It does not typically require a separate database. The CSD files are managed through standard CICS administration tools.

The product operates within the existing CICS network infrastructure. It uses standard TCP/IP ports for communication between CICS regions and terminals. Specific port requirements depend on the CICS configuration.

By compressing 3270 data streams, the product reduces network bandwidth consumption. This can lead to lower network costs, especially in environments with high transaction volumes. Improved response times enhance user productivity and satisfaction.

The product optimizes CICS transaction processing by reducing the amount of data transmitted over the network. This can improve the overall efficiency of CICS applications and reduce CPU utilization.

The product integrates seamlessly with existing CICS environments, minimizing disruption to business operations. It does not require extensive application changes or infrastructure upgrades.

The product leverages existing CICS security mechanisms for authentication and authorization. It does not introduce new authentication methods. Access to configuration parameters is controlled through CICS resource security.

The product uses the CICS resource security model, which is based on access control lists (ACLs). Access to CICS resources, including configuration files and system parameters, is controlled through ACLs.

The product does not encrypt data streams. It focuses on compression to reduce the size of the data transmitted. Encryption is typically handled by other security products or network protocols.

The product provides audit logging capabilities through CICS system logs. It records events related to compression and decompression activities, as well as configuration changes. These logs can be used for security monitoring and auditing.

The product is administered through standard CICS administration tools, such as CEDA and CICS Explorer. These tools provide interfaces for managing CICS resources, including configuration files and system parameters.

User management is handled through CICS security facilities, such as RACF or ACF2. These security products provide mechanisms for defining user profiles and assigning access permissions.

The main configuration parameters include compression levels, compression algorithms, and exclusion lists. These parameters are defined in CICS system definition files (CSD) and can be modified through CICS administration tools.

The product provides monitoring capabilities through CICS monitoring facility (CMF). CMF collects performance data related to compression and decompression activities. This data can be used to monitor the effectiveness of the product and identify potential issues.
