Gravic recently published the second part of the article series, Switching Replication Engines with Zero Downtime. Sometimes it is necessary to change or upgrade to a new data replication engine version. The zero downtime migration approach will impose no downtime on either applications or users. This migration technique is similar to the HPE Shadowbase Zero Downtime Migration (ZDM) technique that customers have been using for decades to upgrade their applications, database schema formats, file and table locations (or indices), operating systems, or perform a hardware refresh. This article discusses how the Version Independence approach discussed in Part 1 of this series can be improved using one or two additional nodes. It also explains how to protect the old production and old standby system(s) while the replication engines are being upgraded or switched.
Gravic published a new Presentations web page on its Publication website pages, featuring the latest HPE Shadowbase data replication software solutions. We hope that you enjoy learning more about these solutions, product updates, use cases, and case study from viewing the following presentations:
Gravic attended the first Latin American NonStop Users Group Meeting (LATUG) at the Renaissance Hotel in picturesque Santiago, Chile.

At NYTUG, Paden Holenstein of Shadowbase Marketing, presented, “HPE Shadowbase Use Case Solutions & Product Update,” which described new HPE Shadowbase features and how it works in several use cases for these solution categories:
Gravic recently published the article, The Better Backup Method. This article discusses strategies for improving database recovery times after catastrophic failure for companies that use the “tried-and-true” backup and restore approach for data recovery. This method focuses on reducing the amount of data that needs to be backed up, stored, and subsequently retrieved for restoring transactional mission-critical databases to a current, consistent, and complete state in order to continue processing. It also focuses on the so-called online backup problem (where the database is open for processing while the backup occurs), and uses several techniques to reduce the amount of data that must be stored while the backup is taking place as well as for the subsequent changes to the data after the backup completes. Since there is a growing need for an economic and efficient way to back up very large-scale databases, many companies are returning to physical tape to fill this need. The better backup method significantly and efficiently uses backup media and backup/restore processing to improve current techniques.
Gravic enjoyed the vibrant city of Leipzig for this Connect Germany and GTUG event and greatly appreciated the warm welcome that the GTUG board and HPE provided us as well as the other vendors and users. It is always exciting to learn about what is happening in HPE and the region, and to discuss how our solutions can help our collective customers. Paul J. Holenstein, Gravic Executive Vice President, presented: New HPE Shadowbase Success Stories (including Business Continuity, Data Integration, Zero Downtime Migrations). He described numerous HPE Shadowbase success stories in several solution categories.

As part of a group of regional partner meetings, Paul Holenstein, Gravic EVP, traveled to Singapore to visit Loreen Teo of Legato Solutions & Services. Paul and Loreen enjoyed crabs over dinner and discussed the Shadowbase presence in the region. Paul also met with HPE NonStop sales and technical teams in Singapore, as well as Bangkok and Jakarta, to discuss HPE Shadowbase customer use cases, product updates, market opportunities, regional sales, and other relevant topics. Paul also found time to enjoy several Southeast Asian attractions.
Gravic recently published the article, Scale-up is Dead, Long Live Scale-out! Keeping up with user demand is a significant challenge for IT departments. The traditional scale-up approach suffers from significant limitations and cost issues that prevent it from satisfying the ever-increasing workloads of a 24x7 online society. The use of massively parallel processing and scale-out architectures is the solution, since they can readily and non-disruptively apply additional compute resources to meet any demand, at a much lower cost, and with improved service availability. The use of a data replication engine, such as HPE Shadowbase, to share and maintain consistent data between multiple systems enables scale-out application and workload distributions across multiple compute nodes, which provides the necessary scalability and availability to meet the highest levels of user demand now and into the future.
The HPE Sales and Presales teams enjoyed our presentation, HPE Shadowbase Use Case Solutions & Product Update, at the HPE APAC MC Boot Camp in Macau. The teams also learned more about the best practices for selling Shadowbase solutions, which are available in the HPE price book. Later, these teams were joined by over 1,200 technical support (TSS) employees from the greater region, who began a week of technical training on product and industry updates. We look forward to participating in the APAC Partner Technical Update in May.

Gravic recently published the article, Protecting Your Vital Applications written for The Connection (January/February issue) by Mark Pollans, HPE Sr. Worldwide Product Manager. This article is based on the excellent and informative presentation that Mr. Pollans gave at the 2017 Connect Technical Boot Camp on how to design and build advanced business continuity (BC) architectures, a rather important topic to Gravic. It is not a question of IF a disaster will occur; it is a matter of WHEN. A thoroughly planned and tested BC strategy helps assure companies that their applications can survive a disaster. BC is about minimizing or completely mitigating the impact of a catastrophe on business applications. A business impact analysis and overall BC strategies should be reviewed at least every two years to confirm that applications meet mission-critical or business-critical requirements. What was not mission-critical yesterday could be mission-critical today. This article also discusses the Critical Application Continuum, recovery time/point objectives (RTO/RPO), costs and durations of outages, and three fundamental data replication architectures: active/passive (classic disaster recovery), active/almost active (sizzling-hot-takeover), and active/active (continuous availability). HPE Shadowbase solutions are instrumental in assisting customers in deploying and leveraging these advanced BC architectures.
Gravic recently published the white paper, Switching Replication Engines with Zero Downtime and Less Risk. Switching replication engines with zero downtime is a topic with immense complexity. In this paper, we discuss how a data replication engine can be changed or upgraded without taking either the application or the database offline. There are numerous methods to thwart common problems faced during a migration: Version Independence (which avoids interoperating different software versions); the challenges when utilizing two nodes; utilizing three nodes (for partial hardware migrations); utilizing four nodes (for a full hardware refresh); and bi-directional environment (that keeps all nodes synchronized as the migration takes place). Additionally, the so-called jagged edge problem must be resolved, which occurs when performing any replication engine migration. HPE Shadowbase software offers several methods to solve these problems, including HPE Shadowbase Zero Downtime Migration, which can upgrade applications, database schema formats, file and table locations or indices, operating systems, and can refresh hardware. Properly undertaken, a data replication engine migration imposes no downtime on applications or users, and the databases all remain accessible, consistent, complete, and up-to-date during the process.
Gravic recently published a technical article, Swapping Replication Engines with Zero Downtime. Sometimes it is necessary to change or update a data replication engine. A zero downtime migration will impose no downtime on either applications or users. The migration can take place during normal working hours and occur over an extended time, while the backup database is always available and fully synchronized with the production database. Therefore, application availability is ensured during the migration process. This migration technique is similar to HPE Shadowbase Zero Downtime Migration (ZDM) that customers have been using for decades to upgrade their applications, database schema formats, file and table locations (or indices), operating systems, or perform a hardware refresh. In this article, we describe how a data replication engine can be changed without taking down either applications or the backup database.
Gravic personnel greatly enjoyed the 2017 Connect HPE NonStop TBC held at the Hyatt Regency San Francisco Airport Hotel. We shared ideas regarding how the HPE Shadowbase product suite can provide solutions to users' most pressing business issues for business continuity, data integration and synchronization, and application integration purposes. We thank Connect and the HPE staff for hosting a terrific gathering. We delivered several presentations, one with Mark Pollans of HPE, one on synchronous bi-directional replication and DB2 source, one on a data integration case study, and one on mission-critical systems with Dr. Highleyman:
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.
