We recently attended and presented on HPE Shadowbase synchronous replication at CTUG (Toronto) and MATUG (Baltimore). We reminded the audience that since HPE NonStop RDF is now approaching mature status, HPE Shadowbase is HPE's go-forward data replication solution. We are grateful to the team that managed the CTUG show, and John Vollers and Peter Schvarcz for helping us plan and manage the MATUG show. Additionally, we thank all of the show participants including customers, vendors, consultants, and HPE executives and technical staff for supporting these wonderful events. Congratulations to Vladislav Sokol from Ministry of Health and Vimal Brahmbhatt from JP Morgan Chase for winning our Google Home prizes at CTUG and MATUG respectively.
Gravic recently dramatically improved the support of HPE Shadowbase for DB2 as a source in data replication environments. With this new release, HPE Shadowbase software makes it easy and cost effective to integrate your DB2 databases into the rest of your data processing environments. HPE Shadowbase data replication can now replicate from DB2 on any IBM platform/environment to any of the supported HPE Shadowbase targets, including HPE NonStop, Oracle, SQL Server, DB2, MySQL, and Sybase. This release also includes replicating DB2 data into non-traditional non-database targets, such as replicating DB2 change data into MQ series, JMS, fraud detection systems, flat-files, real-time business intelligence solutions, and other messaging targets. This latest build includes DB2 databases resident on z/OS IBM mainframe environments, as well as DB2 on AIX, Linux, Windows, etc. Contact your local HPE account team or SBsales@gravic.com for more information.
We attended the ATUG meeting in Atlanta at the Home Depot headquarters, and thank Dale Van Stratten for coordinating the event and Home Depot for allowing us to use its facility. Paul Holenstein presented on our new product, Shadowbase Zero Data Loss (ZDL). Shadowbase ZDL delivers zero data loss and preserves your mission-critical data to eliminate the effects from disasters. Synchronous data replication products do not lose data when a failure occurs. You may want to consider replacing your asynchronous data replication, or else you could corrupt your information during a fail over. Paul also mentioned that since HPE NonStop RDF is now approaching mature status, HPE Shadowbase is HPE's go-forward data replication solution. We are excited and proud to bring Shadowbase ZDL to market, which includes the implementation of many novel and patented techniques. Please contact your HPE account team or contact us if you could benefit from this technology, or are interested in learning more about how Shadowbase replication can replace your RDF implementation. Congratulations to Richard Bernard of Comcast, who won our Google Home prize!
Gravic recently published Prescription Drug Fraud Prevention – An HPE Shadowbase Data Integration Case Study. Prescription drug claims fraud is big business, costing billions of dollars. To help a country’s government healthcare agency stem the losses, a centralized claims fraud adjudication and prevention decision support system was implemented. The agency chose HPE Shadowbase data replication software to provide real-time replication from an HPE NonStop claims processing system to feed the new decision support environment. Shadowbase SOLV enabled the new system to load with no application downtime. This case study provides an excellent example of how new services can be rapidly implemented by using HPE Shadowbase Data and Application Integration facilities.
Gravic recently published a white paper, Shadowbase Synchronous Replication — Product Overview. Shadowbase synchronous replication (Shadowbase Zero Data Loss, or Shadowbase ZDL) resolves two key issues of asynchronous replication: data loss on source system failure and data collisions when running an active/active environment. By eliminating data loss and effectively setting the Recovery Point Objective, or RPO, to zero, Shadowbase ZDL protects your valuable data from having to be recreated after catastrophic failure. This product removes the risk of loss and uncertainty of the status of your data after a failover/takeover. In a future release, by eliminating data collisions, Shadowbase ZDL also allows active/active solutions for applications previously prohibited from running in a continuous availability architecture. There is no need for application/data partitioning or data collision detection and resolution. Removing this need also allows for optimal load-balancing across systems using a “route request anywhere” architecture, resulting in better system capacity utilization. By removing these restrictions, the minimum possible outage and zero data loss for the widest possible range of applications is now a reality. Shadowbase ZDL provides unique differentiating product capabilities for the HPE NonStop market, and is the only choice for business critical applications where even milliseconds of lost data or downtime is unacceptable.
One of the most significant expenses of downtime is data loss, which can cost a company millions of dollars - plus loss of customer confidence, negative publicity, regulatory violations, and even threats to human health and safety. With Shadowbase Zero Data Loss (ZDL), all of these concerns are avoided. Your data is always safe, saving you from the impacts of data loss. Shadowbase ZDL uses unique and patented synchronous replication technology, ensuring that all database changes made on a source system successfully replicate to a target (backup) system.

Gravic publishes new technical article, Achieving Scalability for Mission-Critical Systems in the Cloud. The third pillar of mission-critical systems is scalability; reliability and availability are the other two, creating the acronym RAS. Applications often require additional capacity during critical times. Scalability is an inherent and important attribute of mission-critical systems, since both the servers and the database must be scalable. Active/active systems can provide scalability to servers as well as to the database. However, adding physical servers and disk systems to achieve greater capacity is typically not feasible, especially for temporary additional capacity needs. Scalability can be achieved via the use of active-active systems and Pathway Domains that span multiple HPE NonStop systems. It can also be achieved by bursting applications to RAIC servers (inexpensive commodity hardware) deployed in one or more clouds, where it can be reused between applications, providing an economic cloud platform for scalability-on-demand. For NonStop users, maximizing the RAS for mission-critical systems can now be accomplished by leveraging the new Virtualized NonStop technology.
We enjoyed meeting with Yuji Saeki, Yoshiro Suyama, and Daisuke Horiuchi of High Availability Systems (HAS), the Shadowbase reseller in Japan. HAS explained its future business strategies and what has changed since its recent structure reorganization. Gravic presented on Shadowbase product updates, a zero data loss case study, IBM DB2 as a source, and virtualized NonStop. During the visit the HAS visitors enjoyed a Phillies game and a dinner of Philly cheese steaks, hot dogs, French fries, and beer.
Now that the IBM® MQ V8.0 release is available on HPE NonStop X, we expect many additional HPE NonStop customers to migrate to that platform. HPE Shadowbase software is fully certified on both NonStop X and Virtualized NonStop. Please contact us for more information on migrating with HPE Shadowbase solutions. For more information on the IBM announcement, please see IBM's software announcement.
Gravic recently published a new case study, HPE Shadowbase Software Enables Operational Analytics for Commodity Big Data. HPE Shadowbase software plays a key role in a quality control system for a major U.S. commodity market by integrating applications to extract meaningful data from a mass of test and product quality data, or big data. The system grades and classifies samples from large batches of the commodity as it arrives from the field, to provide real-time analyses on various performance parameters, including moisture content, tensile strength, color, and quality. This information is also used to price the commodity in the spot markets. Extraction is efficient thanks to a series of Online Analytical Processing (OLAP) utilities. The solution has dramatically improved the reporting of the quality metrics for the crop, immediately alarming the users when key parameters are not met, or if the testing equipment goes out of band. It provides for near real-time tactical reporting of crop metrics to the growers (for production analysis), manufacturers (for manufacturing analysis), and markets (for accurate pricing), and provides historical analysis for strategic purposes.
Gravic published a new article, Dramatically Reduce Outage Costs with Advanced Business Continuity Solutions. Whether it be fire, power failure, software error, malfeasance, or some other cause, events occur which can lead to unplanned outages of IT services. If your business is relying on an active/passive or asynchronous data replication solution for business continuity, then it is time to look at whether or not it really provides a sufficient guarantee of protection against the impacts and costs of downtime and data loss. Chances are that it does not, and you should consider moving to a higher level of business continuity solution – such as sizzling-hot-takeover (SZT) or active/active – which mitigate the issues with active/passive, resulting in much better total cost of ownership (TCO). For those businesses that cannot tolerate any downtime or data loss, synchronous replication, HPE Shadowbase ZDL, should be utilized for the highest levels of availability with no data collisions and zero data loss.
We recently attended the N2TUG show in Dallas at the Gaylord Texas Resort, and thank the N2TUG board for hosting such a terrific event! Special thanks to Bill Honaker and Diane Funkhouser for a job well done! As far as regional events go, this is one of the best in the Americas. Paul Holenstein, EVP, attended and presented on our new product, HPE Shadowbase Zero Data Loss (ZDL).

HPE account, sales, and field teams enjoyed and benefited from our Shadowbase Sales Enablement Training as well as product suite update presentations at Partner Technical Updates (PTUs) held in Santiago, Chile; Bogota, Colombia; and Buenos Aires, Argentina. We described how Shadowbase works in various solution categories: business continuity (active/passive through active/active), data integration and synchronization, application integration, and various utility ancillary products, all demonstrated by several use cases. We thank all of the HPE teams for their wonderful hospitality that they shared with us during the trip.
Last week, HPE published a new case study, Cartu Bank ensures continuous availability of payment services for Georgian businesses. Cartu Bank understands the need for continuous availability with more than 60% of all e-commerce transactions in the Eastern European country of Georgia going through its payment switch. Read how HPE NonStop servers with HPE Shadowbase software run mission-critical BASE24 payment engines to keep the Georgian economy running 24x7. Giorgi Ioramashvili, head of Cartu Bank’s IT department, remarks, “It was important to our solution to have replication software like Shadowbase integrated with the NonStop servers. We looked at Oracle GoldenGate, which also could replicate BASE24, but because Shadowbase operates natively within the NonStop operating environment, it was more stable and easier to work with. Plus, Shadowbase was 40% to 50% less expensive than Oracle GoldenGate.”
Gravic recently published a technical article, Improving Reliability via Redundant Processing. One of the three pillars of mission-critical systems is data reliability – a significant concern in data centers worldwide. Data reliability can be ensured via a special configuration that compares the operation of one sub-system to another sub-system running the same applications. Verification may be accomplished by comparing results generated by the two sub-systems at specific synchronization points. If the results agree, the sub-systems are operating properly, if not, corrective action can be taken. This article suggests that the comparison of transaction-processing output via a Transaction Indicia Matching (TIM) module is a significant improvement over the use of a Logical Synchronization Unit (LSU), which represent a single point of failure in a system. A version of a TIM can be implemented with HPE Shadowbase synchronous data replication.
HPE Shadowbase is always ready to take advantage of any new HPE features, such as the just-announced HPE Virtualized NonStop product. This is a very exciting new direction for the HPE NonStop server; it is now a totally software-based solution, which can be deployed on any x86 platform that meets the guidelines of the HPE Virtualized NonStop hardware reference architecture. We were given early access to an HPE Virtualized NonStop environment for testing purposes, and there were no issues. We can happily announce that HPE Shadowbase is HPE Virtualized NonStop ready!
At the SunTUG Sunshine Summit in Tampa, attendees enjoyed our presentation, HPE Shadowbase Synchronous Replication Feature Rollout, announcing HPE Shadowbase Zero Data Loss (ZDL). Data loss as a result of an unplanned outage is a thing of the past with this new release. We discussed major new HPE Shadowbase features, including:
Gravic recently published a new case study, A Large Financial Institution Migrates Datacenters with No Downtime Using HPE Shadowbase ZDM. A major financial company offers person-to-person money transfers, money orders, and business payments. The company implemented an active/active system with two NonStop systems located 1,000 miles apart, and the databases were synchronized with a legacy bi-directional data replication solution. When the company decided to move its systems to other cities, upgrading them in the process, it could not tolerate an application outage during the move, so it relied on HPE Shadowbase Zero Downtime Migration (ZDM) software to avoid application downtime and provide full business continuity protection while the move took place. Its customers were able to make money transfers and use all applications as the servers and services were relocated. The company also relied on HPE Shadowbase ZDM to replace its legacy data replication software product and position itself for continuous availability into the future.
The February issue of the NonStop Insider published the article, Gravic turns up the temperature on synchronous replication. "Let’s talk about something that is hot, really hot! Sizzling hot! From the time Gravic first began talking about Sizzling-Hot-Takeover (SZT) Replication Systems it caught our attention. In presentations given by Gravic it is hard to miss the presence of SZT, occupying a place between Active/Passive and Active/Active replication, and for good reason. Now you can configure your Disaster/Recovery (DR) environment to have some of the benefits of what Active/Active configurations provide without embracing a full-blown Active/Active configuration. Turns out, running applications on the passive system is no longer out of the question."
Part 1 covers MTTF — Mean Time To Failure while Part 2 focuses on Mitigating Redundant Failures via System Staggering. The reliability of a redundant system is optimized by minimizing the probability that both systems will fail simultaneously. If they both have the same failure probability distribution, then when one system is most likely to fail, so is the other system. Previous methods for calculating estimated availability from any point in time are flawed because they are based on memoryless random variables. The calculation of the average time to the next failure is always the same, regardless of how long a system has been in service. By staggering the system starting times so that their probability distributions are not aligned, the time that the two systems are most likely to fail are different. When one system is most likely to fail, the probability that the other system will fail is significantly reduced. Therefore, the probability of a dual system failure is reduced. Redundant system reliability can be greatly enhanced by staggering the starting times of the two systems. This strategy applies both to hardware failures and to software failures.
