Summary

This pattern shows you how to modernize your business-critical mainframe online printing workloads on the Amazon Web Services (AWS) Cloud by using Micro Focus Enterprise Server as a runtime for a modernized mainframe application and LRS VPSX/MFI (Micro Focus Interface) as a print server. The pattern is based on the replatform mainframe modernization approach. In this approach, you migrate your mainframe online application to Amazon Elastic Compute Cloud (Amazon EC2) and migrate your mainframe database, such as IBM DB2 for z/OS, to Amazon Relational Database Service (Amazon RDS). The authentication and authorization for the modernized print workflow is performed by AWS Directory Service for Microsoft Active Directory, also known as AWS Managed Microsoft AD. The LRS Directory Information Server (LRS/DIS) is integrated with AWS Managed Microsoft AD for print workflow authentication and authorization. By modernizing your online printing workloads, you can reduce IT infrastructure costs, mitigate the technical debt of maintaining legacy systems, remove data silos, increase agility and efficiency with a DevOps model, and take advantage of on-demand resources and automation in the AWS Cloud.

Source architecture

The following diagram shows a typical current state architecture for a mainframe online printing workload:

The diagram shows the following workflow:

  1. Users perform business transactions on a system of engagement (SoE) that’s built on an IBM CICS application written in COBOL.

  2. The SoE invokes the mainframe service, which records the business transaction data in a system-of-records (SoR) database such as IBM DB2 for z/OS.

  3. The SoR persists the business data from the SoE.

  4. A user initiates a request to generate print output from the CICS SoE, which initiates a print transaction application to process the print request. 

  5. The print transaction application (such as a CICS and COBOL program) extracts data from the database, formats the data according to business requirements, and generates business output (print data) such as billing statements, ID cards, or loan statements. Then, the application sends a print request by using Virtual Telecommunications Access Method (VTAM). A z/OS print server (such as IBM Infoprint Server) uses NetSpool or a similar VTAM component to intercept the print requests, and then creates print output datasets on the JES spool by using JES output parameters. The JES output parameters specify routing information that the print server uses to transmit the output to a particular network printer. The term VTAM refers to the z/OS Communications Server and the System Network Architecture (SNA) services element of z/OS.

  6. The printing output transmission component transmits the output print datasets from the JES spool to remote printers or print servers, such as LRS (as demonstrated in this pattern), IBM Infoprint Server, or email destinations.

Target architecture

The following diagram shows an architecture for a mainframe online printing workload that’s deployed in the AWS Cloud:

The diagram shows the following workflow:

  1. A user initiates a print request from an online (CICS) user-interface to create print output, such as billing statements, ID cards, or loan statements.

  2. The mainframe online application (replatformed to Amazon EC2) uses the Micro Focus Enterprise Server runtime to extract data from the application database, apply business logic to the data, format the data, and then send the data to a print destination by using Micro Focus CICS Print Exit (DFHUPRNT). 

  3. The application database (an SoR that runs on Amazon RDS) persists data for print output.

  4. The LRS VPSX/MFI printing solution is deployed on Amazon EC2, and its operational data is stored in Amazon Elastic Block Store (Amazon EBS). LRS VPSX/MFI uses a TCP/IP-based LRS/Queue transmission agent to collect print data through the Micro Focus CICS Print Exit API (DFHUPRNT) and deliver the data to a specified printer destination. The original TERMID (TERM) that’s used in the modernized CICS application is used as the VPSX/MFI Queue name. 

Note: The target solution typically doesn’t require application changes to accommodate mainframe formatting languages, such as IBM Advanced Function Presentation (AFP) or Xerox Line Condition Data Stream (LCDS). For more information about using Micro Focus for mainframe application migration and modernization on AWS, see Empowering Enterprise Mainframe Workloads on AWS with Micro Focus in the AWS documentation.

AWS infrastructure architecture

The following diagram shows a highly available and secure AWS infrastructure architecture for a mainframe online printing workload:

The diagram shows the following workflow:

  1. The mainframe online application (written on a programming language such as CICS or COBOL) uses core business logic to process and generate print output, such as billing statements, ID cards, and loan statements. The online application is deployed on Amazon EC2 across two Availability Zones (AZ) for high availability (HA) and uses Micro Focus CICS Print Exit to route print output to LRS VPSX/MFI for end-user printing.

  2. LRS VPSX/MFI uses a TCP/IP-based LRS/Queue transmission agent to collect or capture print data from the Micro Focus online Print Exit programming interface. Online Print Exit passes the necessary information to enable LRS VPSX/MFI to effectively process the print file and dynamically build LRS/Queue commands. Note: For more information on various CICS application programing methods for print and how they are supported in Micro Focus Enterprise server and LRS VPSX/MFI, see Print data capture in the Additional information section of this pattern.

  3. A Network Load Balancer provides a DNS name to integrate Micro Focus Enterprise Server with LRS VPSX/MFI. Note: LRS VPSX/MFI supports a Layer 4 load balancer. The Network Load Balancer also does a basic health check on LRS VPSX/MFI and routes traffic to the registered targets that are healthy.

  4. The LRS VPSX/MFI print server is deployed on Amazon EC2 across two Availability Zones for HA and uses Amazon EBS as an operational data store. LRS VPSX/MFI supports both the active-active and active-passive service modes. This architecture uses multiple Availability Zones in an active-passive pair as an active and hot standby. The Network Load Balancer performs a health check on LRS VPSX/MFI EC2 instances and routes traffic to hot standby instances in another Availability Zone if an active instance is in an unhealthy state. The print requests are persisted in the LRS Job Queue locally in each of the EC2 instances. In the event of recovery, a failed instance has to be restarted for the LRS services to resume processing the print request. Note: LRS VPSX/MFI can also perform health checks at the printer fleet level. For more information, see Printer fleet health checks in the Additional information section of this pattern.

  5. AWS Managed Microsoft AD integrates with LRS/DIS to perform print workflow authentication and authorization. For more information, see Print authentication and authorization in the Additional information section of this pattern.

  6. LRS VPSX/MFI uses Amazon EBS for block storage. You can back up Amazon EBS data from active EC2 instances to Amazon S3 as point-in-time snapshots and restore them to hot standby EBS volumes. To automate the creation, retention, and deletion of Amazon EBS volume snapshots, you can use Amazon Data Lifecycle Manager to set the frequency of automated snapshots and restore them based on your RTO/RPO requirements.

Considerations

During your modernization journey, you may consider a wide variety of configurations for mainframe online processes and the output they generate. The mainframe platform has been customized by every customer and vendor that uses it with particular requirements that directly affect print. For example, your current platform may incorporate the IBM Advanced Function Presentation (AFP) or the Xerox Line Condition Data Stream (LCDS) into the current workflow. Additionally, mainframe carriage control characters and channel command words can affect the look of the printed page and may need special handling. As part of the modernization planning process, we recommend that you assess and understand the configurations in your specific print environment.

Print data capture

This section summarizes the CICS application programming methods that you can use in an IBM mainframe environment for printing. LRS VPSX/MFI components provide techniques to allow the same application programs to create data in the same way. The following table describes how each application programming method is supported in a modernized CICS application running in AWS and Micro Focus Enterprise Server with an LRS VPSX/MFI print server.

Method

Description

Support for the method in a modernized environment

EXEC CICS SEND TEXT..    or EXEC CICS SEND MAP..

These CICS and VTAM methods are responsible for creating and delivering 3270/SCS print data streams to LUTYPE0, LUTYPE1, and LUTYPE3 print devices.

A Micro Focus online Print Exit (DFHUPRNT) application program interface (API) enables print data to be processed by VPSX/MFI when 3270/SCS print data streams are created by using either of these methods.

EXEC CICS SEND TEXT..    or EXEC CICS SEND MAP.. (with third-party IBM mainframe software)

The CICS and VTAM methods are responsible for creating and delivering 3270/SCS print data streams to LUTYPE0, LUTYPE1, and LUTYPE3 print devices. Third-party software products intercept the print data, convert the data to standard print format data with an ASA/MCH control character, and place the data on the JES spool to be processed by mainframe-based printing systems that use JES.

A Micro Focus online Print Exit (DFHUPRNT) API enables print data to be processed by VPSX/MFI when 3270/SCS print data streams are created by using either of these methods.

EXEC CICS SPOOLOPEN

This method is used by CICS application programs to write data directly to the JES spool. The data then becomes available to be processed by mainframe-based printing systems that use JES.

Micro Focus Enterprise Server spools the data to the Enterprise Server spool where it can be processed by the VPSX/MFI Batch Print Exit (LRSPRTE6) that spools the data to VPSX.

DRS/API

An LRS-supplied programmatic interface is used for writing print data to JES.

VPSX/MFI supplies a replacement interface that spools the print data directly to VPSX.

Printer fleet health checks

LRS VPSX/MFI (LRS LoadX) can perform deep dive health checks, including device management and operational optimization. Device management can detect failure in a printer device and route the print request to a healthy printer. For more information about deep dive health checks for printer fleets, see the LRS documentation that’s included with your product license.

Print authentication and authorization 

LRS/DIS enables LRS applications to authenticate user IDs and passwords by using Microsoft Active Directory or an LDAP server. In addition to basic print authorization, LRS/DIS can also apply granular-level print security controls in the following use cases:

  • Manage who can browse the printer job.

  • Manage the browsing level of other user's jobs.

  • Manage operational tasks. For example, command-level security such as hold/release, purge, modify, copy, and reroute. Security can be set up by either the User-ID or Group (similar to AD group or LDAP group).
