What infrastructure is required?

QPAC for CICS requires a CICS environment on z/OS or zVSE/VSEn. It integrates with data sources such as DB2, VSAM, and IMS. Ensure these subsystems are properly configured and accessible from CICS.

For mainframe products: Does this run in an LPAR?

QPAC for CICS operates within a CICS LPAR. It is dependent on the z/OS or zVSE/VSEn operating system and requires CICS Transaction Server to be installed and configured.

What are the main system components?

The core components include the QPAC compiler, runtime library, and interactive development environment (if available). These components work together to compile, execute, and manage QPAC applications within CICS.

How does QPAC for CICS interact with other systems?

QPAC applications interact with CICS using standard CICS APIs. Data access to DB2, VSAM, and IMS is typically achieved through CICS file control and database access facilities.

What is the business value of using QPAC for CICS?

QPAC for CICS allows organizations to rapidly develop and deploy CICS applications, reducing development time and costs. It simplifies data access and reporting, enabling faster decision-making.

What happens if an organization does NOT use this product?

By using QPAC for CICS, organizations can avoid the need for extensive COBOL or PL/I programming for CICS applications. This reduces the skills required and accelerates application delivery.

When is QPAC for CICS a good fit?

QPAC for CICS is well-suited for organizations that need to maintain and enhance existing CICS applications. It provides a more productive development environment compared to traditional languages.

How does QPAC for CICS handle security?

QPAC for CICS leverages CICS security features for authentication and authorization. Access to data and resources is controlled through CICS resource definitions and security profiles.

What specific authentication methods are supported?

QPAC for CICS relies on CICS for authentication methods, which can include RACF, ACF2, or Top Secret. These external security managers control user access to CICS resources.

What access control model is used?

QPAC for CICS utilizes the CICS access control model, which is primarily based on resource definitions and security profiles. These profiles define which users or groups have access to specific CICS resources.

How is QPAC for CICS typically deployed?

QPAC for CICS is typically deployed on-premise within a CICS environment. Implementation requires expertise in CICS administration, security configuration, and QPAC programming.

What ongoing operational requirements exist?

Ongoing operational requirements include monitoring CICS performance, managing QPAC applications, and ensuring the availability of data sources. Regular maintenance of CICS and related subsystems is essential.

What administrative interfaces are available?

Administrative interfaces are provided through CICS transaction CESN to log on and CEDA to define, install, and manage resources. QPAC applications are managed through these CICS facilities.

Product Overview

QPAC for CICS is a 4GL programming language designed to operate within the CICS transaction processing environment. It provides a higher-level language for developing applications that access and process data from various sources, including DB2, VSAM, and IMS databases. The architecture of QPAC for CICS includes the QPAC compiler, runtime library, and integration with CICS facilities.

The QPAC compiler translates QPAC code into executable code that runs within the CICS environment. The runtime library provides the necessary functions for data access, manipulation, and reporting. QPAC applications are deployed and managed through standard CICS facilities, such as CEDA for resource definition and CESN for logon.

QPAC integrates with CICS security features, leveraging CICS resource definitions and security profiles to control access to data and resources. Communication between QPAC applications and data sources is typically achieved through CICS file control and database access facilities. Alternatives include CA RAMIS and other 4GL languages, but QPAC's tight integration with CICS provides a streamlined development experience.
