Let Oracle GoldenGate 12c Take You to the Cloud

If your organization is in the ~80% of the global business community, you are most likely working on a cloud computing strategy for your organization, or actively implementing. The cloud computing growth rate is 5X more than the overall IT growth rate because of the clear and already proven cost savings, agility, and  scalability benefits of cloud architectures.

When organizations decide to embark on their cloud journey, they notice there are several questions and challenges to be addressed, involving data accessibility, security, availability, system management, performance etc. Oracle GoldenGate's real-time data integration and bi-directional transactional replication technology addresses critical challenges such as:

  • How to move my systems to the cloud without interrupting operations?
  • How to enable timely data synchronization between the systems on the cloud and on-premises to ensure access to consistent data for all end users?
  • How do I run operational reports with the data I have in cloud environments, or feed my analytical systems in cloud solutions?
  • In managed or private clouds, how do I keep the cloud platform highly available when I need to do maintenance, upgrades?

 On Tuesday,  December 2nd we will tackle these questions in a free webcast:

Zero Downtime Consolidation to Oracle Database 12c: Webcast Recap

As companies move to private cloud implementations to increase agility and reduce costs, and start their plans with consolidating their databases, a major question arises: how do we move our systems without causing major disruption to the business. At the end, the most important systems that need to move to this new architecture are the ones that cannot tolerate extensive downtime for any reason. In last week’s webcast “Zero Downtime Consolidation to Oracle Database 12c with Oracle GoldenGate 12c” we tackled this specific dilemma that IT organizations face. The webcast is now available on demand via the link above in case you missed it last week.

In the webcast, we started discussing the benefits companies achieve when they consolidate to a private database cloud, critical database capabilities to deliver database as a service, and a quick overview Oracle Database 12c features that enable private database clouds deployments. Nick Wagner, director of product management for Oracle Database High Availability, talked about the new Global Data Services feature in Oracle Database Maximum Availability Architecture (MAA) as well. Global Data Services helps organizations to handle challenges involved with managing multiple database replicas across different sites. The product manages database replicas of Active Data Guard and Oracle GoldenGate products, and offers workload balancing to maximize performance as well as intelligent handling of outages using all available replicas. Nick also discussed the database features available for upgrading, migrating, and consolidating into Oracle Database 12c and when it makes sense to use Oracle GoldenGate for these efforts.

After Nick, Chai Pydimukkala from senior director of product management for GoldenGate discussed some of the key new features of Oracle GoldenGate 12c for Oracle Database and its expanding heterogeneity that supports consolidation from all major databases. Chai continued his presentation with GoldenGate’s solution architecture for zero downtime consolidation and explained how it minimizes risk with failback option as well as via the phased migration option by running old and new environments concurrently.

Chai also gave an example on how Oracle Active Data Guard customers can seamlessly use GoldenGate for a zero downtime migration without affecting their standby system for high ongoing high availability and disaster recoery. After customer examples we had a long Q&A section. For the full presentation and Q&A with the experts you can watch the on-demand version of the webcast via the following link.

Zero Downtime Consolidation to Oracle Database 12c with Oracle GoldenGate 12c

In the rest of this blog post, I provided  answers to some of the questions we could not take in the live event. 

1) Additional difference in features between GoldenGate 11g and 12c?

Please take a look at our previous blog posts below where we discussed many of the new features of GoldenGate 12c.

· Advanced Replication for The Masses – Oracle GoldenGate 12c for the Oracle Database.

· GoldenGate 12c - What is Coordinated Delivery?

· GoldenGate 12c - Coordinated Delivery Example

· Oracle GoldenGate 12c - Announcing Support for Microsoft and IBM

You can also listen to our podcast: Unveiling Oracle GoldenGate 12c

More comprehensive information can be found in the webcast replay  Introducing Oracle GoldenGate 12c: Extreme Performance Simplified or GoldenGate 12c resource kit.

2) Does GoldenGate have a term license that customer can purchase for migration purposes?

We do offer 1 year license that customer can be used for this purposes.

3) Is there a Oracle Tutorial on configuring and testing Zero downtime upgrade using GoldenGate?

Here is a high level outline/tutorial for the migration. It will require some knowledge of how to setup GoldenGate and configuration.

Oracle GoldenGate Best Practice: Oracle Migrations and Upgrades 9i and up

A more broad discussion of this topic can be found in the following white paper. Zero Downtime Database Upgrades using Oracle GoldenGate 12c

4) If the number of updates to the database is very high, does GoldenGate give some kind of compression to transfer the Trail Files and be up to date with the changes?

Oracle GoldenGate does provide support of compress of change data in the Trail File to better the transfer throughput from source to target with the usage of COMPRESS and COMPRESSTHRESHOLD. 

RMTHOST

{host_name | IP_address}

{, MGRPORT port | PORT port}

[, COMPRESS]

[, COMPRESSTHRESHOLD]

[, ENCRYPT algorithm [KEYNAME key_name]]

[, PARAMS collector_parameters]

[, STREAMING | NOSTREAMING]

[, TCPBUFSIZE bytes]

[, TCPFLUSHBYTES bytes]

[, TIMEOUT seconds]

COMPRESS

This option is valid for online or batch Capture processes and any Oracle GoldenGate initial-load method that uses Trails. Compresses outgoing blocks of records to reduce bandwidth requirements. Oracle GoldenGate decompresses the data before writing it to the Trail. COMPRESS typically results in compression ratios of at least 4:1 and sometimes better. However, compressing data can consume CPU resources.

COMPRESSTHRESHOLD

This option is valid for online or batch Capture processes and any Oracle GoldenGate initial-load method that uses trails. Sets the minimum block size for which compression is to occur. Valid values are from 0 and through 28000. The default is 1,000 bytes.

5) Can the Source system utilize 12C GoldenGate for DML/DDL capture and target system utilize GoldenGate 11g?

Yes.  You can replicate from a higher version of GoldenGate to a lower version using FORMAT RELEASE option. 

FORMAT RELEASE <major>.<minor>

In the on demand replay of the webcast you will find more questions answered by our product management experts. So make sure to watch the on demand webcast as well.

No Way Out, But to Consolidate

IT teams receive pressures on multiple fronts: Business groups demand new application services delivered faster and continuous, high-quality IT service to support highly dynamic and competitive business operations. In the meanwhile IT teams are asked to reduce costs and improve ROI from existing systems in highly complex and siloed environments.

In the midst of this conundrum, the only way out for IT leadership is to consolidate and leverage cloud architecture. Especially consolidation at the database level and implementing a private database-as-a-service (DBaaS) environment is a transformative approach to delivering database functionality to end users in an agile, efficient, and scalable way.  It helps organizations improve resource utilization, and lower both capital and operational expenditures.

Oracle Database 12c is designed to support database consolidation with many new features for deploying shared database environment. The new multitenant architecture, simplified management capabilities, improvements to security and compliance, along with robust and flexible Maximum Availability Architecture, are only a few of the key differentiators.

While this all sounds good and logical for IT teams, when it comes to moving to a private database cloud, they face yet another major challenge: How do we move our critical systems to a new environment without interrupting our operations. In today’s 24/7 world, especially customer-facing systems cannot tolerate hours or days of downtime. For some of them, even few minutes of downtime can bring high costs to the business. As in each major project, risk involved with moving to a new system is a real deterrent factor too.

Oracle GoldenGate 12c offers the core capabilities to enable this major move to a database as a service environment. With its optimized support for Oracle Database 12c multitenant architecture and heterogeneous data replication capabilities, Oracle GoldenGate allows organizations to avoid business disruption while the systems are moving to a consolidated, DBaaS environment. In addition, Oracle GoldenGate offers a failback option to the old environment, or a phased migration option by running old and new systems simultaneously in active-active mode, to minimize risks. Oracle GoldenGate’s heterogeneity includes all major database vendors and operating systems including SQL Server, DB2 (LUW, z/Os, iSeries), Sybase ASE, HP NonStop and more. 

In our webcast Zero Downtime Consolidation to Oracle Database 12c with Oracle GoldenGate 12c on May 13th 10am PT we will present this solution with specific architecture examples and comparison to other database upgrade options.

Zero Downtime Consolidation to Oracle Database 12c with Oracle GoldenGate 12c

May 13th, 10am PT/ 1pm ET

If your organization needs to improve agility, increase innovation, and reduce costs, I invite you to join this webcast to learn how to remove the risk and business interruption barriers to move to an agile and cost-efficient private database cloud.

What Comes Next After You Decide on Using Oracle Exadata

As Oracle Exadata continues to expand its footprint for both transaction and analytical processing, moving existing systems to Exadata and feeding it with enterprise data on an ongoing basis have become important discussion topics for Exadata customers. Consolidation and migration is the first step of this powerful journey with Exadata, and I'd like to start there in today's blog post.   

The systems that benefit from Exadata's extreme performance and reliability are typically business-critical systems that carry major risks when it comes to migration. Any downtime or data loss can have significant impact to the business in terms of revenue generation, customer loyalty, and productivity. As Oracle GoldenGate user community knows well, GoldenGate's heteregenous, real-time, and bidirectional replication capabilities enable very strong zero downtime migration and consolidation solutions for major databases and platforms including Oracle, IBM DB2 (zOS, iSeries, and LUW), HP NonStop, SQL Server, Sybase ASE, MySQL, and Teradata.

We discussed GoldenGate's zero downtime migration to Exadata offering and best practices with our customer IQNavigator in a webcast that is now available on demand:

Zero-Downtime Migration to Oracle Exadata Using Oracle GoldenGate: A Customer Case Study

If you have not watched it, I highly recommend listening to the discussion, as it clearly explains there should be no concerns around causing business interruption when moving to Oracle Exadata using GoldenGate.  GoldenGate's failback option to the old environment is a great tool for minimizing risk and many organizations adopt that approach for their business-critical systems.  

In addition to migration to Oracle Exadata, customers use GoldenGate, and Oracle Data Integrator, with Exadata in a variety ways leveraging the natural fit between these technologies:

  • Active-active database synchronization across the globe for data distribution, continuous availability, and zero downtime maintenance purposes.
  • Real-time or near real-time data loading to data warehouse, or consolidated database, on Oracle Exadata from heterogeneous sources. Oracle Data Integrator plays the major role in this use case as it integrates with GoldenGate and loads data warehouse in near real-time after performing transformations within the Exadata machine. This use case will be another blog topic soon as it is a strong best practice for performing ETL/ E-LT for Exadata.
  • Moving change data from an OLTP application running on Exadata in real time, for downstream consumption by other systems including supporting service integration.

As additional resources on best practices for migrating to Exadata I'd like to point you to couple of great white papers: Zero-Downtime Migration to Oracle Exadata Using Oracle GoldenGate and Oracle GoldenGate on Exadata Database Machine.

And the Winners of Fusion Middleware Innovation Awards in Data Integration are…

At OpenWorld, we announced the winners of Fusion Middleware Innovation Awards 2012. Raymond James and Morrison Supermarkets were selected for the data integration category for their innovative use of Oracle’s data integration products and the great results they have achieved.

In this blog I would like to briefly introduce you to these award winning projects.

Raymond James is a diversified financial services company, which provides financial planning, wealth management, investment banking, and asset management. They are using Oracle GoldenGate and Oracle Data Integrator to feed their operational data store (ODS), which supports application services across the enterprise. A major requirement for their project was low data latency, as key decisions are made based on the data in the ODS. They were able to fulfill this requirement due to the Oracle Data Integrator’s integrated solution with Oracle GoldenGate.

Oracle GoldenGate captures changed data from different systems including Oracle Database, HP NonStop and Microsoft SQL Server into a single data store on SQL Server 2008. Oracle Data Integrator provides data transformations for the ODS. Leveraging ODI’s integration with GoldenGate, Raymond James now sees a 9 second median latency (from source commit to ODS target commit).

The ODS solution delivers high quality, accurate data for consuming applications such as Raymond James’ next generation client and portfolio management systems as well as real-time operational reporting. It enables timely information for making better decisions.

There are more benefits Raymond James achieved with this implementation of Oracle’s data integration solution. The software developers and architects of this solution, Tim Garrod and Ryan Fonnett, have told us during their presentation at OpenWorld that they also reduced application complexity significantly while improving developer productivity through trusted operational services. They were able to utilize CDC to generate alerts for business users, and for applications (for example for cache hydration mechanisms).

One cool innovation example among many in this project is that using ODI's flexible architecture, Tim and Ryan could build 24/7 self-healing processes. And these processes have hardly failed. Integration process fixes the errors itself. Pretty amazing; and a great solution for environments that need such reliability and availability. (You can see Tim and Ryan’s photo with the Innovation Awards trophy above.)

The other winner of this year in the data integration category, Morrison Supermarkets, is the UK’s 4th largest grocery retailer. The company has been migrating all their legacy applications on to a new-world application set based on Oracle and consolidating all BI on to a single Oracle platform. The company recently implemented Oracle Exadata as the data warehouse engine and uses Oracle Business Intelligence EE.

Their goal with deploying GoldenGate and ODI was to provide BI data to the enterprise in a way that it also supports operational decision making requirements from a wide range of Oracle based ERP applications such as E-Business Suite, PeopleSoft, Oracle Retail Suite. They use GoldenGate’s log-based change data capture capabilities and Oracle Data Integrator to populate the Oracle Retail Data Model. The electronic point of sale (EPOS) integration solution they built processes over 80 million transactions/day at busy periods in near real time (15 mins). It provides valuable insight to Retail and Commercial teams for both intra-day and historical trend analysis.

As I mentioned in yesterday’s blog, the right data integration platform can transform the business. Here is another example: The point-of-sale integration enabled the grocery chain to optimize its stock management, leading to another award: Morrisons won the Grocer 33 award in 2012 - beating all other major UK supermarkets in product availability. Congratulations, Morrisons,on another award!

Celebrating the innovation and the success of our customers with Oracle’s data integration products was definitely a highlight of Oracle OpenWorld for me. I look forward to hearing more from Raymond James, Morrisons, and the other customers that presented their data integration projects at OpenWorld, on how they are creating more value for their organizations.

Leaders Discuss at OpenWorld: Achieving Zero Downtime Upgrades and Migrations

OpenWorld brings us another exciting session about a hot topic: system upgrades and migrations. This time it is a panel discussion between industry leaders that undertook pretty large projects with strict requirements for minimizing downtime. Fedex, SiriusXM Radio, and Dell will talk about the best practices they followed in their highly-critical migration projects and how they removed the risk of interrupting business operations leveraging Oracle GoldenGate.

On this blog site and in many of our webcasts we have talked about Oracle GoldenGate’s unique solution for upgrades and migrations. GoldenGate’s real-time, bi-directional, and heterogeneous data replication capabilities enable to switch over to the new system without downtime. It also offers a failback option by keeping the old system in synch after the switchover,  in case the new system experiences a problem. In this session, we will hear from these select customers how they configured GoldenGate for their unique project requirements.

Fedex will talk about how they are moving their data centers, and SiriusXM Radio will talk about how they consolidated data models for subscription management system after the merger. Dell’s discussion will include how they migrated their Active-Active replication environment that used Oracle Streams in the past to Oracle GoldenGate.

If you will be at Open World, and have any plans for systems upgrades or migrations, don’t miss the opportunity to hear the real-life implementation stories, lessons learned and, best practice tips.

What’s New in the Data Integration Market?

Data integration is essential to many strategic IT initiatives including master data management (MDM), modernization, and service-oriented architecture (SOA). That’s why it is not surprising that the data integration market continues to grow in its size, importance and impact on enterprise information systems. The technology has evolved from simple extract, transform, and load (ETL) procedures to include real time data movement, bi-directional replication/synchronization along with data quality and data profiling and data services.

 The user base for data integration tools has also evolved from low-level technology for developers and DBAs to high-level environments for operations staff, data stewards, business analysts and enterprise architects. In short, what was once merely the background “plumbing” underlying our information systems now influences just about every aspect of IT, and touches just about every type of stakeholder.

 In a new white paper we have examined the state of the data integration market including the trends in business intelligence, data warehousing, data quality, consolidation, cloud computing and IT modernization initiatives that are driving data-intensive projects. You can access this brand new white paper along with other data integration focused white papers and resources here.
