Treehouse Software Eases the Challenges for Mainframe-to-Modern Platform Transformation Programs for Systems Integrators

Unlock Your Customers’ Business Value Faster with Frequent Production Deliveries, Using Agile Methods

Treehouse Software’s product, tcVISION has proven to be vital for the ease and success of many mainframe modernization initiatives.

A big problem for a Systems Integrator (SI), or any mainframe modernization vendor, is the myriad of dependencies between mainframe and open systems data and components. As part of a mainframe modernization project, these vendors need to determine the ordering of phases or waves of applications to be migrated. There are often shared databases that can make it very difficult to move one set of applications without moving others. This can result in the conclusion that they must go with a “big bang” approach, which can lead to a bid for a program with one large delivery at the end with all of the integrated components in place. This is very unappealing to customers as they are paying out big dollars without the corresponding business value of a production deployment. This approach also significantly increases the project risk.

With Treehouse Software’s bi-directional replication product, tcVISION, a subset of applications can be migrated, and tcVISION’s data synchronization capabilities can be used to bridge specific shared legacy mainframe databases to the modern database versions on open systems. This allows them to deliver in phases, thus getting modernized modules in production faster. In addition, it decreases risk as issues can be found much faster with the more frequent production deployments. When the last modules are deployed to production, they would no longer need the synchronization.

As an example, a large Treehouse customer is currently involved in gradually modernizing and replacing a set of applications, and is using a similar approach. The customer will be using their mainframe Adabas database synced with Oracle on Linux, while in the process of modernizing the applications. Treehouse Software’s experts and tcVISION product are making sure the customer’s transition goes smoothly and seamlessly.


Enterprise ETL and Real-Time Data Replication Between Virtually Any Source and Target

tcVISION supports a vast array of integration scenarios throughout the enterprise, providing easy and fast data migration for mainframe application modernization projects and enabling bi-directional data replication between mainframe, Linux, Unix and Windows platforms. This innovative technology offers comprehensive abilities to identify and capture changes occurring in mainframe and relational databases, then publish the required information to an impressive variety of targets, both on-premise and Cloud-based.

tcVISION acquires data in bulk or via change data capture methods, including in real time, from virtually any IBM mainframe data source (Software AG Adabas, IBM DB2, IBM VSAM, IBM IMS/DB, CA IDMS, CA Datacom, sequential files), and transform and deliver to virtually any target. In addition, the same product can extract and replicate data from a variety of non-mainframe sources, including Adabas LUW, Hadoop/HDFS, MongoDB, Oracle Database, Microsoft SQL Server, IBM DB2 LUW and DB2 BLU, IBM Informix, PostgreSQL, etc.

TREETIP: Integrate Mainframe Data Sources In Your Big Data Initiatives

tcVISION supports a vast array of integration scenarios throughout the enterprise, providing easy and fast data migration for mainframe application modernization projects and enabling bi-directional data replication between mainframe, Linux, Unix and Windows platforms. This innovative technology offers comprehensive abilities to identify and capture changes occurring in mainframe and relational databases, then publish the required information to an impressive variety of targets, both on-premise and Cloud-based.

Analysts have observed that perhaps 80 percent of the world’s corporate data still resides on mainframes. So it’s no surprise that Bloor Research (http://www.bloorresearch.com/research/spotlight/big-data-and-the-mainframe/), notes that “it is necessary today to place the mainframe as a ‘first-class player’ in any enterprise Big Data strategy.”

In February 2017 we highlighted tcVISION’s support for replication to the leading NoSQL database MongoDB. MongoDB continues to increase in popularity as a back end for operational applications with real-time requirements.

tcVISION also supports analytics and “mainframe offload” Big Data use cases that generally leverage Hadoop HDFS and/or streaming data transport. With tcVISION, data from a wide variety of IBM mainframe data source can be quickly and easily replicated to Big Data targets, requiring minimal mainframe know-how and having minimal impact on the mainframe.

TREETIP: tcVISION Allows for Surprisingly Innovative Uses

tcVISONv6

Treehouse Professional Services consultants help Adabas / Natural customers in a variety of ways, including DBA services, performance tuning, change management implementation and training, and data replication planning and training. Our experience and long history of service to the Adabas / Natural community helps us create innovative solutions for our customers’ challenges.

Recently Treehouse Senior Technical Representative Chris Rudolph assisted a customer with a tricky data replication problem. The customer uses tcVISION to perform bi-directional replication between Adabas and an RDBMS during the phase-in of a new application. Unfortunately, the new application incorrectly updated certain columns in the RDBMS, which were then replicated to Adabas. The customer attempted to address the issue by running a series of ADASEL reports against the Adabas PLOG and manually checking for “bad” transactions, which was a very time consuming process that pulled the Adabas DBA away from her normal duties.

Chris explained that tcVISION could expedite the process by replicating all transactions for the Adabas file to a journal table capturing the “before” and “after” values of the problematic columns. The developers working on the new application could then identify invalid values, correct the application, and patch the data themselves. This also allowed the Adabas DBA to return to their normal duties.

The journal table now includes columns to display the “before” and “after” values of the corrupted column, Adabas transaction time, end transaction time, operation and Adabas userid. The customer’s developers immediately recognized immense value from being able to query the journal table to find bad data, patch the data, prove that corruption is no longer taking place, and verify that all corrupted instances of the data have been patched. Journal tables have been added for all replicated Adabas files, and the developers now rely on the journal tables for all of their data patches.

PRODUCT SPOTLIGHT: tcVISION v6 Overview and Updates

tcVISONv6

Several exciting new features and updates are now in tcVISION v6, including new output targets Adabas LUW, DB2 BLU, EXASOL, Hadoop,and MongoDB. Additionally, new input sources include z/OS VSAM Logstream (CICS and Coupling Facility / Shared VSAM),z/OS VSAM Batch Extension, z/OS DBMS to Logstream, CA IDMS v17, CA Datacom CDC, IMS Active Log and SMF data.

Another feature recently announced is the tcVISION “Direct Loader” for BULK_LOAD processing. The function does not require output to a sequential file, and the loader utility for the target DBMS is called via API with data passed directly. Direct loader supports PostGreSQL, Microsoft SQL Server and DB2 LUW / DB2 BLU. The advantage of using the Direct Loader is the elimination of disk access in writing and reading the sequential loader data file. File output is still supported (e.g., where loader data is to be distributed to other machines).

Finally, as mentioned in a previous Treehouse Blog, with tcVISION v6 comes the newly enhanced web statistics functionality and web server. Any standard web browser can access this server (Internet Explorer, Firefox, Opera, Chrome, Safari, etc.)

This valuable feature enables users to view data from the tcVISION Manager Monitor, and statistical and operational information from the tcVISION Manager network.
