Mainframe Modernization: Extracting Business Value While Maintaining Critical Legacy Data

_0_Treehouse_tcV_Cloud_OpenSystems

Whether your enterprise wants to take advantage of the latest cloud services, such as analytics, artificial intelligence (AI), etc., or move your data to a variety of newer LUW or Open Systems databases, the transition doesn’t have to be a sudden big bang.

Application Rehost / Modernization Challenges

Much of an enterprise’s mission critical mainframe data is stored in legacy mainframe databases, and the cost to maintain these databases is high.  An added complication is that the data is utilized by many interlinked and dependent programs that have been in place for many years, and sometimes, decades. Unlocking the value of this legacy data is difficult due to many very different types of mainframe databases (e.g., Db2, Adabas, CA Datacom, CA IDMS, etc.).

Many customers are looking for a solution that allows their legacy environment to continue while replicating data in real time on a modern database/platform. This enables them to utilize modern programing and data tools in order to remain competitive in their markets.

One Step At A Time…

Treehouse Software has extensive experience in helping 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 developed a phased plan that includes installation and implementation of the tcVISION mainframe data replication product. The plan then defines various parts of the solution, including:

  • configuration management
  • environments and promotion
  • high availability
  • security
  • disaster recovery
  • monitoring
  • operations procedures
  • script customization
  • data replication mapping
  • training

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

This phased plan enables the tcVISION product to synchronize mission critical mainframe data to any modern 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.

Customer Success: tcVISION / Hadoop Integration

_tcVISION_Customer_Hadoop_Header

BAWAG P.S.K. is one of the largest and most profitable banks of Austria with more than 1.6 million private and business customers and a well known brand in the country. The business strategy is oriented towards low risk and high efficiency. Business segments are Retail Banking and Small Business, Corporate Lending and Investments and Treasury Services and Markets. The center of the BAWAG P.S.K. business strategy is the offering of easy to understand, transparent and first-rate products and services which meet the requirements of the customers.

The BAWAG P.S.K. Bank für Arbeit und Wirtschaft and Österreichische Postsparkasse Aktiengesellschaft ” (P.S.K.), Vienna, operates their IT on the z/OS operating system. The corporate data is stored in DB2 databases. ORACLE is the database platform for the Open System environments. In relationship with another project P.S.K already had a client component of tcVISION installed. Magister Markus Lechner, Head IT Applications: “tcVISION was already in use and we had good experiences as far as functionally and support is concerned. Because we were in the planning process for the implementation of another project, we included tcVISION in the list of software solutions. The goal of this project has been the reduction of the load on the IBM mainframe and as a result the reduction of costs. The intention was to offload data from our core database system to a less expensive system in real-time and to provide read access from that system to the new infrastructure. The reasons for this were constantly increasing CPU costs on the mainframe because of the growing transaction load of the Online Banking, Mobile Banking, and Self Service devices. A large percentage of the load was caused by Read-Only-Transactions.” Markus Lechner: “After the tcVISION presentation, we arranged a Proof Of Concept. The important aspects of the POC were not only the functionality of tcVISION within the project but we also wanted to see whether our expectations would be met related to performance and CPU consumption on the mainframe. In addition to tcVISION, we also evaluated another product. All of our expectations have been met to our full satisfaction during the POC and we made the decision to go ahead with tcVISION.”

After a short implementation period, the project is now in production for one year. Markus Lechner describes the project: “The primary objective of the project with tcVISION was the reduction of CPU load on the mainframe to reduce our costs. Our intention was to offload data from our core database system to a less expensive system in real-time and to provide read access from that system to the new infrastructure.

tcVISION_Hadoop

We use tcVISION for the realtime replication and we use Apache Hadoop as a cost efficient system for the storage of the data. In addition to the primary usage scenario we have the benefit to also cover additional use cases. This includes Real-time-EventHandling & Stream Processing, Analytics based upon real-time data as well as the possibility to report and analyze structured and unstructured data with excellent performance. The system can be inexpensively operated on Commodity Hardware and has no scalability limitations. Compared to the savings the costs of replication (CPU consumption) of tcVISION are very low. The support provided  was excellent during the implementation phase and also during the production phase. Inquiries by telephone or E-mail cause prompt reactions. Problems that came up during this period were solved as soon as possible even when the tcVISION software had to be extended.” There are additional plans to extend the use of tcVISION in the future. One is to implement real-time replication from ORACLE into the data lake.

Magister Markus Lechner draws a conclusion: “tcVISION enables us to significantly reduce our mainframe cost through a real-time replication to a less expensive environment. tcVISION performs a very economical log file based replication. In addition we are now in a position to implement numerous application cases based upon the replicated data which would have been too expensive and resource intensive on the mainframe. Realtime-Event-handling, Realtime-Analytics, Realtime-Fraud Prevention are only a few of the use cases that we currently cover.”


tcVISION

_0_tcVISION_Simple_Diagram

tcVISION enables bidirectional replication for DB2, Oracle, and SQL Server running on Linux/Unix/Windows, and synchronizes each data source, first by doing a bulk load from source(s) to target and then by replicating only changes— only committed changes—from source(s) to target. So there can never be ambiguity as to whether a query against the target database involves uncommitted data.

This is a follow-up to our recent Treehouse Software Blog entry “Treehouse Software is Setting Sights on Many New Data Replication Projects”, in which we described a typical customer visit to implement data replication.

Treehouse representatives were on-site at a state government agency to configure tcVISION and set up bulk transfer and change data capture, as well as train the State employees on using and managing tcVISION. In a subsequent discussion with our contacts at the site, they reported that their deadline for delivering a reporting database in Microsoft SQL Server replicated from 63 ADABAS files has been met. They also happily noted that by using tcVISION, the bulk transfer of 60 million ADABAS records into SQL Server completed in only 20 minutes.

We are very pleased to have yet another satisfied customer benefitting from one of Treehouse Software’s mature and proven enterprise software solutions.

tcVISION provides real-time data replication through change data capture, and allows easy and fast data migration for mainframe application modernization projects. Enterprises looking for a product that enables bi-directional heterogeneous data replication between mainframe, Linux, Unix, and Windows platforms need look no further than to tcVISION from Treehouse Software.

Cloud-y … with a 100 Percent Chance of Data

cloud computing and downloading

by Wayne Lashley, Chief Business Development Officer for Treehouse Software

Along with three of my colleagues, I recently participated in the Treehouse exhibit at the Gartner Application Architecture, Development and Integration (AADI) event in Las Vegas. This is a conference where we have exhibited in the past, and I personally have attended several other times. In fact, I just learned that the DI in AADI no longer stands for “Data Integration”; this change was only made in the past couple of years, as in the past it was the data integration aspect that made the show particularly relevant to Treehouse.

Though data integration vendors such as Informatica, Pervasive and Adeptia—and Treehouse—were in attendance, their numbers seemed diminished over prior years. And while “Legacy Modernization” had an entire subject “track” a couple of years ago, a number of “name” LM vendors were notably absent this year, and the topic was only rarely represented in sessions.

But there was a predominant theme at the event, and its name is Cloud.

People have been talking about “Cloud” for years already, and it is a well-established concept with many dimensions and extensive implementations. And it’s probably familiar enough to The Branches readers that I won’t waste words describing it, other than to say that it is simply a way to offer computing services via the Internet without the subscriber—most Cloud offerings are subscription-based—knowing or caring what or where the physical implementation is.

Many people consider that Salesforce.com is the granddaddy of all Cloud services, and to my mind it popularized the term “Software as a Service” (SaaS). Evolutionary Technologies, Inc. (ETI), a long-standing player in the data integration field and a company that I have had a lot of contact with over the years, reinvented itself around 2005 as a SaaS company, in doing so placing the company on the leading edge of “aaS” providers and essentially defining an entirely new market space.

These days there are a number of other “aaS” genres competing for mindshare and dollars, the most dominant being “Platform as a Service” (PaaS). Once again, Salesforce.com seemed to define the space initially, but others such as Amazon and Google have since come to dominate it. Just this week I was invited to an event for Oracle partners where Oracle executives will present their concept for an Oracle Cloud PaaS. I recall a Microsoft Worldwide Partners Conference (WWPC) a couple of years ago where Microsoft kicked off its Azure Cloud platform. You don’t have to install Microsoft Office on your PC anymore; Office 365 runs in the Cloud.

Even legacy applications are getting the Cloud treatment: a company called Heirloom Computing has commenced offering a platform for running legacy COBOL applications in the Cloud.

Cloud has also entered popular culture and commodity services. There’s a TV commercial that I keep seeing advertising a Cloud-based service that automatically troubleshoots, tunes up and cleans up your PC.
In short, you’re nobody if you’re not in the Cloud.

D-for-“Data” may have morphed into D-for-“Development” in the AADI Summit name, but data replication, integration and migration remain very relevant in the Cloud age. Indeed, you can’t spell Cloud without a D.

To support provisioning of Cloud-based applications, there has to be a means for getting data from where it is now—often in mainframe-based legacy databases or relational databases on open systems, within a company’s internal IT infrastructure—to the Cloud facilities, be they public or private. This doesn’t happen by magic. We have recently been working in a customer implementation where Oracle and DB2 data are being replicated bidirectionally in a Cloud implementation using our tcVISION solution. Such a scenario posed a bit of a challenge for us in terms of licensing: the machines on which tcVISION is installed are not specifically known at a given point in time. So we had to adapt our licensing model to accommodate the new reality.

We expect to see continued growth and demand for our replication and integration solutions as Cloud offerings evolve and expand. Furthermore, we are working on a new Cloud-oriented solution in collaboration with Cloud platform providers. I have briefed several Gartner analysts on it, and their feedback has been encouraging. Check back to this space regularly for news on this exciting new Treehouse offering.
