What are the main system components?

The core components include the Compression Engine, the Interceptor, and the Configuration Manager. The Compression Engine performs the actual data compression and decompression. The Interceptor intercepts the 3270 data stream. The Configuration Manager handles the product's settings.

What compression algorithms are used?

The product uses a proprietary compression algorithm optimized for 3270 data streams. The specific algorithm details are proprietary. The product dynamically selects the optimal compression method based on the data characteristics.

What protocols and ports are used for communication?

The product uses TCP/IP for communication between the CICS region and the terminal emulator. The Interceptor component listens on a configurable port for incoming 3270 data streams. The default port is typically 23, but this can be changed during configuration.

How is the product configured?

Configuration is managed through a combination of JCL and a configuration file. The JCL is used to start and stop the product components. The configuration file contains parameters such as compression levels, port numbers, and logging settings.

What are the key business benefits of using this product?

The primary business value is reduced network bandwidth consumption, leading to cost savings. Improved response times enhance user productivity. The product's transparent operation minimizes the risk and cost associated with application changes.

How does the product contribute to cost savings?

By compressing 3270 data, the product reduces the amount of data transmitted over the network. This can lead to significant cost savings, especially for organizations with high volumes of 3270 traffic. The reduction in data volume also improves network performance.

How does the product improve user experience?

The product improves user experience by reducing the time it takes for data to be displayed on the terminal. Faster response times increase user productivity and satisfaction. This is achieved without requiring any changes to the CICS applications.

How does the product minimize risk and cost?

The product's transparent operation minimizes the risk and cost associated with application changes. This allows organizations to implement compression without disrupting existing CICS applications. The ease of deployment and use reduces the total cost of ownership.

What authentication methods are supported?

The product does not directly provide authentication. Security is maintained through the existing CICS and network security infrastructure. Secure connections can be established using standard network security protocols.

What access control model is used?

Access control relies on the underlying z/OS security mechanisms, such as RACF or equivalent security managers. The product itself does not implement its own access control model. Access to the product's configuration and management interfaces is controlled through these existing security systems.

What encryption is used and where?

Data compression and decompression are performed within the product's components. Data transmitted over the network can be secured using standard network security protocols, such as TLS/SSL, if configured in the network environment.

What administrative interfaces are available?

The primary administrative interface is the z/OS console. Operators can use console commands to start, stop, and monitor the product. A configuration file is used to manage settings.

How is user management handled?

User management is handled through the z/OS security system (e.g., RACF). The product itself does not have its own user management features. Access to the product's administrative functions is controlled through the z/OS security system.

What are the main configuration parameters?

Key configuration parameters include compression levels, port numbers, and logging settings. These parameters are set in the product's configuration file. The configuration file is read at startup.

What monitoring/logging capabilities exist?

The product provides logging and monitoring capabilities. Logs record events, errors, and performance metrics. Monitoring tools can be used to track resource usage and performance. These tools integrate with standard z/OS monitoring systems.

Product Overview

The product's architecture comprises three main components: the Compression Engine, the Interceptor, and the Configuration Manager. The Compression Engine is responsible for the actual compression and decompression of the 3270 data streams. It utilizes a proprietary compression algorithm optimized for 3270 data.

The Interceptor is the component that intercepts the 3270 data stream. It listens on a configurable port (default 23) for incoming 3270 data streams. The Interceptor is responsible for capturing the data and passing it to the Compression Engine for processing.

The Configuration Manager is responsible for managing the product's configuration settings. The configuration is stored in a configuration file, which is read at startup. The configuration file contains parameters such as compression levels, port numbers, and logging settings.

The product communicates using TCP/IP. The Interceptor listens on a configurable port for incoming 3270 data streams. The compressed data is then transmitted over the network to the terminal emulator.

The product integrates with existing z/OS security. The product provides logging capabilities to record events, errors, and performance metrics. These logs can be used for auditing and troubleshooting.

The level of detail in the logs is configurable through the product's configuration settings. The product does not require changes to CICS applications.

Frequently Asked Questions

What is the primary function of this product?

The product compresses 3270 data streams without requiring changes to existing CICS applications. It intercepts and compresses data between the CICS region and the 3270 terminal emulator. This reduces network bandwidth usage and improves response times.

How does the compression process work?

The product operates by intercepting the 3270 data stream and applying compression algorithms. The compressed data is then transmitted over the network. On the receiving end, the data is decompressed before being displayed on the terminal. This process is transparent to the CICS application and the end-user.

What 3270 terminal types and emulators are supported?

The product supports various 3270 terminal types and emulators. It is compatible with standard 3270 data streams. Specific terminal compatibility details are available in the product documentation.

Does this product require changes to existing CICS applications?

The product is designed to minimize impact on existing CICS applications. No modifications to application code are required for the compression to function. The product integrates seamlessly into the existing CICS environment.
