CICS Interdependency Analyzer Modernization Guide

CICS Interdependency Analyzer automatically discovers application program relationships within a CICS environment. It analyzes CICS, Db2, IMS, and IBM MQ command flows to provide a comprehensive view of application dependencies.

The analyzer identifies dependencies by examining the execution flow of transactions and programs. It traces calls between CICS programs, interactions with Db2 databases, IMS transactions, and IBM MQ message queues.

Yes, CICS Interdependency Analyzer includes a plugin for CICS Explorer, allowing users to visualize and analyze dependencies directly within the CICS Explorer interface.

The tool helps in understanding complex application landscapes, identifying potential points of failure, and optimizing application performance by revealing hidden dependencies.

The analyzer uses configuration files to define the scope of analysis, including CICS regions, Db2 subsystems, IMS systems, and IBM MQ queue managers. These files specify the resources to be included in the dependency analysis.

CICS Interdependency Analyzer exposes APIs that allow integration with other tools and systems. These APIs can be used to extract dependency information, automate analysis tasks, and integrate with reporting and monitoring systems.

The main system components include the data collector, which gathers information from CICS, Db2, IMS, and IBM MQ; the analysis engine, which processes the collected data to identify dependencies; and the reporting interface, which presents the analysis results.

The administrative interface is typically accessed through a web console or a dedicated client application. User management is handled through z/OS security mechanisms such as RACF, ACF2, or Top Secret.

By visualizing application dependencies, the tool helps reduce the risk of outages caused by unintended changes. It also assists in impact analysis, allowing users to understand the potential consequences of modifications before they are implemented.

The tool helps optimize resource allocation by identifying underutilized or overutilized components. It also aids in capacity planning by providing insights into application resource consumption patterns.

CICS Interdependency Analyzer supports application modernization efforts by providing a clear understanding of existing application architectures. This knowledge facilitates the migration of applications to newer platforms or technologies.

Authentication is typically handled through z/OS security mechanisms such as RACF, ACF2, or Top Secret. The access control model is often based on role-based access control (RBAC), where users are assigned roles with specific permissions.

Encryption is used to protect sensitive data both in transit and at rest. Data transmitted between components may be encrypted using SSL/TLS, while data stored in databases may be encrypted using database-specific encryption mechanisms.

CICS Interdependency Analyzer provides audit logging capabilities that track user access, configuration changes, and other security-related events. These logs can be used to monitor security activity and investigate potential security breaches.

The administrative interface provides monitoring dashboards that display system status, resource utilization, and other key performance indicators. Logging capabilities capture system events, errors, and warnings, which can be used to troubleshoot issues.

Configuration parameters include settings for data collection, analysis, and reporting. These parameters can be adjusted to optimize performance, customize analysis results, and control resource consumption.

The tool supports automated data collection and analysis, which reduces the need for manual intervention. It also provides customizable reports that can be generated on a scheduled basis.
