High Availability Requirements for Mainframe Data Modernization — Running tcVISION in Global Availability Zones

by Joseph Brady, Director of Business Development / Cloud Alliance Lead at Treehouse Software, Inc.

Many customers embarking on Mainframe-to-Cloud data replication projects with Treehouse Software are looking at high availability (HA) as a key consideration in the planning process. The goal with HA is to ensure that systems are always functioning and accessible, with deployments located in various Availability Zones (AZs) worldwide. Having an HA architecture in place protects against data center, availability zone, server, network, and storage subsystem failures to keep businesses running without downtime or human intervention.

In this blog, we will give a high-level overview of tcVISION HA Architecture, using AWS as an example. However, HA basic principles are essentially the same across all Cloud platforms.

Example of the tcVISON HA Architecture on AWS

During tcVISION’s Change Data Capture (CDC) processing for Mainframe-to-Cloud data replication, HA must be maintained in the AWS environment. The Amazon Elastic Compute Cloud (Amazon EC2), which contains the tcVISION Manager, is part of an Auto Scaling Group that is spread across AZs with Amazon EC2 instance(s).

___tcVISION_AWS_HA_Architecture

Upon failure, the replacement Amazon EC2 instance tcVISION Manager is launched and communicates its IP address to the mainframe tcVISION Manager. The mainframe tcVISION Manager then starts communication with the replacement Amazon EC2 tcVISION Manager.

Once the Amazon EC2 tcVISION Manager is restarted, it continues processing at its next logical restart point, using a combination of the LUW and Restart files. LUW files contain committed data transactions not yet applied to the target database. Restart files contain a pointer to the last captured and committed transaction and queued uncommitted CDC data. Both file types are stored on a highly available data store, such as Amazon Elastic File System (EFS).

For production workloads, Treehouse Software recommends turning on Multi-AZ target and metadata databases.

To keep all the dynamic data in an HA architecture, tcVISION uses EFS, which provides a simple, scalable, fully managed elastic file system for use with AWS Cloud services and on-premises resources. It is built to scale on-demand to petabytes without disrupting applications, growing and shrinking automatically as you add and remove files, eliminating the need to provision and manage capacity to accommodate growth.


Treehouse Software can help organizations immediately start moving their mainframe data to the Cloud and take advantage of the most advanced, scalable, secure, and highly available technologies in the world with tcVISION

Now, more than ever, enterprises with mainframes are looking to modernize their legacy systems

by Joseph Brady, Director of Business Development / Cloud Alliance Lead at Treehouse Software, Inc.

Rapidly changing global health, economic, and political conditions are making fast access to the most current information more important than ever for official agencies and the public.  As a result, modernizing information systems is taking center stage and top priority, especially for organizations with critical mainframe data residing on a variety of long-standing databases, often still updated by COBOL applications! These databases include Db2, VSAM, IMS/DB, Adabas, IDMS, Datacom, or even sequential files. Unlocking the value of this important data can be difficult, because the data can be utilized by numerous interlinked and dependent programs that have been in place for many years, and sometimes decades.

Many organizations are now looking for modernization solutions that allow their legacy mainframe environments to continue, while replicating data in real time on highly available Cloud-based platforms (AWS, Google Cloud, Microsoft Azure, etc.). With a “data-first” approach, immediate data replication to the Cloud is enabling government, healthcare, supply chain, financial, and a variety of public service organizations to meet spikes in demand for vital information, especially in times of crisis.

Treehouse Software can help organizations immediately start moving their mainframe data to the Cloud and take advantage of the most advanced technologies in the world with tcVISION

tcVISION_Overall_Diagram_General_Cloud

Whether an enterprise needs to take advantage of the latest Cloud services, such as big data analytics, artificial intelligence (AI), rapid global database deployments, high-level security, etc., or move data to a variety of newer Cloud or Open Systems databases, the transition doesn’t have to be a sudden big bang.

A Phased Approach

Treehouse Software has extensive mainframe experience and subject matter experts to help organizations incrementally replicate their mainframe data to the Cloud and other modern systems, while keeping both sides synchronized.

Treehouse Software’s expert technical representatives help customers develop a phased plan that includes installation and implementation of the tcVISION mainframe data modernization product, script customization, data replication mapping, high availability, security, monitoring, training, etc..

After defining the architecture, the production deployment phase begins with incremental sprint-like deployments. Additional files are then deployed into production regularly.

This phased plan enables tcVISION to synchronize critical mainframe data to a Cloud / Open Systems database. Bi-directional, real-time data synchronization allows changes on either platform to be reflected on the other platform (e.g., a change to a PostgreSQL table is reflected back on mainframe). The customer can then modernize their application on the cloud, open systems, etc. without disrupting the existing critical work on the legacy system.

Additionally, tcVISION customers see drastically reduced mainframe MIPS costs, and increased ability to quickly respond to business environment changes.

A real-world example of how Treehouse Software is helping enterprises with their Mainframe-to-Cloud / LUW / Open Systems data migration and replication initiatives…

by Joseph Brady, Director of Business Development for Treehouse Software

Many medium to large size companies are still investing in new mainframe systems, because they have been relying on them for decades to handle mission critical data transaction processing. For these companies, their mainframes are deeply entrenched, and have been rock-solid reliable over the years, allowing many users and applications to simultaneously access the same data without interfering with each other. Mainframes also perform large-scale and extremely fast transaction processing (thousands of transactions per second). Chances are, most transactions for which you use your debit or credit cards have a mainframe processing the data in the background.

There have been countless predictions of the demise of the mainframe over the years, but they have been proven wrong every time, and there’s no sign of extinction any time soon. Mainframes remain a vital part of IT infrastructures used by companies spanning a variety of industries around the world, including banking, insurance, healthcare, government, aviation, and retail.

Today, most companies that have their enterprise data stored on a mainframe system are discovering the advantages of newer cloud and open systems databases and services, including instantaneous global database deployments (e.g., Amazon Aurora), economics to scale, high availability, elasticity, security, testing at scale, disaster recovery, etc. Consequently, these companies are looking for an automated solution that allows real-time data replication between the two environments, and many are turning to Treehouse Software.

Customer Scenario: A Look at a Large Airline’s Mainframe Data Replication Project

Treehouse Software has a major airline customer that is a long-time user of Software AG’s Adabas database on their mainframe system. Their desire was to move their data to more modern applications off of the mainframe. However, their mainframe contains vital airline maintenance and parts data that must always be highly available, so rather than performing a complete migration from the mainframe, the customer decided to utilize a data warehouse with a requirement of real-time data replication. This allows the mainframe legacy teams to maintain existing applications, while the modernization team develops applications on the newly created RDBMS. All teams determined that tcVISION real-time mainframe data replication was the perfect fit for meeting their goals.

How tcVISION Addressed the Customer Needs...

The high-level environment for the airline customer using tcVISION for data replication looks like this…

___Airline_tcV_Overview

  • Adabas: Mainframe data source containing business critical information replicated to the RDBMS.
  • Oracle: Open Platform RDBMS chosen by customer as replication target for both data warehouse and modernization project. The tcVISION Manager also uses Oracle as a repository for the metadata (field mappings).
  • tcVISION Manager: Software component deployed on both source and target systems. It is responsible for provisioning resources for:
    • Processing scripts
    • Metadata import
    • Scheduling
  • tcSCRIPT: Software component deployed on both source and target systems. It works in conjunction with the tcVISION Manager to:
    • Perform initial load of Adabas into Oracle
    • Ongoing near realtime CDC (Change Data Capture) and replication from Adabas to Oracle
    • tcSCRIPT processes data from:
      • Direct from the DBMS (initial load) or from DBMS extracts
      • Adabas Protection log (PLOG)
  • tcVISION Control Board: Software component deployed on a Windows machine which provides graphical user interface for a single point of control to administer the tcVISION environment:
    • Metadata import, creates metadata rules governing relationship between mainframe and open platform data structures
    • Replication rule maintenance
    • DDL creation
    • Creation of ETL and replication processes
    • Start, stop, and schedule replication processes

Customer’s Technical Requirement for tcVISION

The airline requires that the replication solution must support online and batch Adabas transactions and provide data replication between Adabas and Oracle. Additionally, their large databases contain millions of rows (e.g., > 50 million) that must be supported, as well as support for database change audit requirements (datetime and type of operation), transaction management, and notification of exception events.

There must also be support for configuration management between development, QA, and production.

Finally, the solution must address hardware and software failures on the mainframe, Linux, and database nodes.

Customer Outcomes

All requirements were met by tcVISION, which led to a successful project implementation.  Here is a look at the customer outcomes and benefits:

Business Outcome Customer Benefit
Data warehouse is always in sync with Adabas using tcVISION data replication Improved timeliness and reliability of reporting data
Reduced usage of mainframe MIPS Reduced cost
All data required for modernization project was successfully replicated to target environment Increased business efficiently and agility
