Frequently Asked Questions

General

What was the primary function of CICS Performance Monitor?

CICS Performance Monitor provided real-time and historical data on CICS transaction processing. It allowed administrators to identify performance bottlenecks and optimize resource utilization within the CICS environment.

What type of data did CICS Performance Monitor collect?

CICS Performance Monitor collected data related to transaction response times, CPU utilization, I/O activity, and storage usage. This data helped in diagnosing performance issues and capacity planning.

How was performance data presented to users?

The monitor used a combination of online displays and batch reporting to present performance data. Users could view real-time statistics or generate historical reports for analysis.

Who were the typical users of CICS Performance Monitor?

CICS Performance Monitor was primarily used by system administrators, performance analysts, and capacity planners to ensure optimal performance and availability of CICS applications.

Technical

What type of database or storage mechanism did CICS Performance Monitor use?

CICS Performance Monitor used VSAM datasets to store collected performance data. These datasets were accessed by the monitor's components for reporting and analysis.

How did CICS Performance Monitor communicate with CICS regions?

The monitor communicated with CICS regions using inter-region communication (IRC) and inter-system communication (ISC) facilities. These facilities allowed the monitor to collect data from multiple CICS regions.

What administrative interfaces were available?

The primary administrative interface was a set of CICS transactions and panels. These transactions allowed administrators to configure the monitor, start and stop data collection, and view performance data.

What monitoring and logging capabilities existed?

The monitor provided detailed logging capabilities, recording events such as data collection start and stop times, error conditions, and configuration changes. These logs were used for auditing and troubleshooting.

Business Value

What were the main business benefits of using CICS Performance Monitor?

By providing detailed performance data, CICS Performance Monitor helped organizations reduce downtime, improve application response times, and optimize resource utilization. This resulted in cost savings and increased business productivity.

How did CICS Performance Monitor help with proactive problem detection?

The monitor enabled proactive problem detection by identifying performance bottlenecks before they impacted users. This allowed administrators to take corrective actions and prevent service disruptions.

How did CICS Performance Monitor support capacity planning?

The historical data collected by the monitor was used for capacity planning, helping organizations to forecast future resource needs and avoid performance issues as transaction volumes grew.

Security

How did CICS Performance Monitor handle security?

CICS Performance Monitor relied on the security features of the z/OS operating system and CICS transaction server. It used CICS resource security to control access to monitor functions and data.

What authentication methods were supported?

The monitor supported authentication through CICS user IDs and passwords, which were validated against the z/OS security manager (e.g., RACF, ACF2, or Top Secret).

What access control model was used?

The access control model was based on CICS resource security, which allowed administrators to define which users or groups had access to specific monitor transactions and data.

What audit and logging capabilities existed for security events?

The monitor provided audit logging of security-related events, such as user logon attempts, transaction executions, and security violations. These logs were used for security auditing and compliance.

Operations

What configuration was required to operate CICS Performance Monitor?

CICS Performance Monitor required configuration of CICS regions to enable data collection. This involved defining monitor transactions, setting up VSAM datasets, and configuring security parameters.

How was CICS Performance Monitor administered?

The monitor was administered through a set of CICS transactions and panels. These transactions allowed administrators to start and stop data collection, view performance data, and manage user access.

What monitoring capabilities were available?

The monitor provided online displays and batch reports for monitoring CICS performance. These displays and reports showed real-time and historical data on transaction response times, CPU utilization, and other key metrics.

What type of events were logged by CICS Performance Monitor?

The monitor logged events such as data collection start and stop times, error conditions, and security violations. These logs were used for troubleshooting and auditing.
