Problem Analysis and Recovery 3270 CICS

Vendor

MacKinney Systems

Product Overview

The architecture of Show and Tell II is designed for seamless integration within a CICS environment. The core components include the 'Show' transaction, the 'Tell' transaction, and associated data structures. The 'Show' transaction captures screen data from a specified CICS transaction using CICS APIs.

This data is then formatted and transmitted to the requesting terminal. The 'Tell' transaction broadcasts the current screen to multiple connected users. Communication relies on standard 3270 data streams for screen display and CICS internal communication mechanisms for transaction processing.

There are no external APIs exposed. The product integrates directly with CICS, utilizing CICS security profiles for access control. All activity is logged through CICS facilities.

The product's design prioritizes minimal overhead and efficient data transfer within the CICS environment. The system does not use any external databases or storage mechanisms. The 'SHOW' and 'TELL' transactions are defined within CICS, and their behavior is controlled through CICS resource definitions.

The system is designed to be non-intrusive, minimizing the impact on existing CICS resources.

Frequently Asked Questions

What are the primary functions of Show and Tell II?

undefined

Show and Tell II provides two core functions for CICS environments: 'Show' allows users to view a CICS screen from another CICS session, and 'Tell' enables the broadcasting of a master CICS screen to multiple other screens. This facilitates monitoring, training, and collaborative troubleshooting across CICS applications.

undefined

How does Show and Tell II integrate with CICS?

undefined

Show and Tell II integrates directly with CICS as a set of transactions. The product utilizes CICS APIs to capture and display screen data. No external agents or middleware are required, ensuring minimal impact on existing CICS infrastructure.

undefined

What are the key components of Show and Tell II?

undefined

The core components include the 'Show' transaction, the 'Tell' transaction, and associated data structures for screen capture and display. These components interact directly with CICS to provide the screen sharing functionality. The system leverages CICS internal mechanisms for efficient data transfer.

undefined

What protocols are used for communication?

undefined

Show and Tell II uses standard CICS protocols for communication. It leverages the 3270 data stream for screen display and CICS internal communication mechanisms for transaction processing. No external network protocols are required.

undefined

How does Show and Tell II handle screen data?

undefined

Show and Tell II captures screen data directly from the CICS region using CICS APIs. The data is then formatted and transmitted to the requesting terminal or broadcast to multiple terminals. The process ensures minimal overhead and preserves the integrity of the screen display.

undefined

What are the system requirements for running Show and Tell II?

undefined

Show and Tell II requires a z/OS or z/VSE environment with a running CICS region. It is compatible with standard 3270 terminals or emulators. Minimal system resources are needed, ensuring compatibility with existing infrastructure.

undefined

How does Show and Tell II improve troubleshooting?

undefined

Show and Tell II enables real-time screen sharing, allowing support teams to view and diagnose issues collaboratively. This reduces the time required to identify and resolve problems, leading to faster resolution times and improved system availability. The 'Tell' feature allows for simultaneous monitoring of multiple screens.

undefined

How does Show and Tell II support training?

undefined

Show and Tell II facilitates effective training by allowing trainers to demonstrate CICS screens to multiple trainees simultaneously. The 'Tell' feature enables instructors to broadcast screen actions, providing a shared learning experience. This enhances training effectiveness and reduces training time.

undefined

What is the return on investment (ROI) of Show and Tell II?

undefined

The ROI of Show and Tell II is realized through reduced troubleshooting times, improved training efficiency, and enhanced collaboration. By minimizing downtime and optimizing support processes, the product contributes to significant cost savings and increased productivity.

undefined

How does Show and Tell II contribute to compliance?

undefined

Show and Tell II supports compliance by enabling real-time monitoring of CICS screens, which can be used to ensure adherence to operational procedures and security policies. The ability to observe screen activity aids in identifying and addressing potential compliance issues.

undefined

What authentication methods are supported?

undefined

Show and Tell II leverages CICS security features for authentication. User access is controlled through CICS sign-on and security profiles. The product does not introduce separate authentication mechanisms, relying on the existing CICS security infrastructure.

undefined

What access control model is used?

undefined

Show and Tell II utilizes the CICS access control model, which is based on user IDs and security profiles. Access to the 'Show' and 'Tell' transactions is managed through CICS resource definitions and security settings, ensuring that only authorized users can use the features.

undefined

Are there any encryption capabilities?

undefined

Show and Tell II does not provide built-in encryption. Security is managed through the underlying CICS environment. Data transmitted within CICS is protected by the security measures configured in CICS.

undefined

What audit/logging capabilities exist?

undefined

Show and Tell II integrates with CICS auditing and logging mechanisms. All transaction activity, including the use of 'Show' and 'Tell', is logged according to the CICS audit configuration. This provides a comprehensive audit trail of screen sharing activities.

undefined

How is Show and Tell II administered?

undefined

Administration of Show and Tell II involves defining CICS transactions and security profiles. Configuration parameters are managed through CICS resource definitions. No separate administrative interface is provided; all administration is performed within the CICS environment.

undefined

How is user management handled?

undefined

User management is handled through CICS security profiles. Access to the 'Show' and 'Tell' transactions is granted or denied based on user IDs and security group memberships defined within CICS. This ensures consistent user access control.

undefined

What are the main configuration parameters?

undefined

The main configuration parameters involve defining the CICS transactions 'SHOW' and 'TELL', and setting up the appropriate security profiles. No other specific configuration parameters are required. The product is designed for ease of setup within the CICS environment.

undefined

What monitoring and logging capabilities exist?

undefined

Show and Tell II leverages CICS monitoring and logging capabilities. All transaction activity is logged through CICS facilities. Performance metrics can be monitored using standard CICS monitoring tools. No separate monitoring tools are provided.
