Recap of Oracle GoldenGate 12c Webcast with Q&A

Simply amazing! That’s how I would summarize last week’s webcast for Oracle GoldenGate 12c.  It was a very interactive event with hundreds of live attendees and hundreds of great questions. In the presentation part my colleagues, Doug Reid and Joe deBuzna, went over the new features of Oracle GoldenGate 12c. They explained Oracle GoldenGate 12c key new features including:

  • Integrated Delivery for Oracle Database,
  • Coordinated Delivery for non-Oracle databases,
  • Support for Oracle Database 12c multitenant architecture,
  • Enhanced high availability via integration with Oracle Data Guard Fast-Start Failover,
  • Expanded heterogeneity, i.e. support for new databases and operating systems,
  • Improved security,
  • Low-downtime database migration solutions for Oracle E-Business Suite,
  • Integration with Oracle Coherence.

We also had a nice long and live Q&A section. In the previous Oracle GoldenGate webcasts, we could not respond to all audience questions in a 10-15 minute timeframe at the end of the presentation. This time we kept the presentation part short and left more than 30 minutes for Q&A. To our surprise, we could not answer even half of the questions we received. 

If you missed this great webcast discussing the new features of Oracle GoldenGate 12c,  and more than 30 minutes of Q&A with GoldenGate Product Management, you can still watch it on demand via the link below.

On Demand Webcast: Introducing Oracle GoldenGate 12c: Extreme Performance Simplified

On this blog post I would like to provide brief answers from our PM team  for some of the questions that we were not able to answer during the live webcast.

1) Does Oracle GoldenGate replicate DDL statements or DML for Oracle Database?

    Oracle GoldenGate replicates DML and DDL operations for Oracle Database and Teradata.

2) Where do we get more info on how to setup integration with Data Guard Fast-Start Failover (FSFO)?

     Please see the following blog posts or documents on My Oracle Support:

Best Practice - Oracle GoldenGate and Oracle Data Guard - Switchover/Fail-over Operations for GoldenGate    [My Oracle Support Article ID   1322547.1] 

Best Practice - Oracle GoldenGate 11gr2 integrated extract and Oracle Data Guard - Switchover/Fail-over Operations  [My Oracle Support Article ID 1436913.1] 

3) Does GoldenGate support SQL Server 2012 extraction? In the past only apply was supported.

Yes, starting with the new 12c release GoldenGate captures from SQL Server 2012 in addition to delivery capabilities.

4) Which RDBMS does GoldenGate 12c support?

GoldenGate supports all major RDBMS. For a full list of supported platforms please see Oracle GoldenGate certification matrix.

5) Could you provide some more details please on Integrated Delivery for dynamic parallel threads at Target side?

Please check out our white papers on Oracle GoldenGate 12c resource kit for more details on the new features, and how Oracle GoldenGate 12c works with Oracle Database. 

6) What is the best way to sync partial data (based on some selection criterion) from a table between databases?

 Please refer to the article: How To Resync A Single Table With Minimum Impact To Other Tables' Replication? [Article ID 966211.1]

7) How can GoldenGate be better than database trigger to push data into custom tables?

Triggers can cause high CPU overhead, in some cases almost double compared to reading from redo or transaction logs. In addition, they are intrusive to the application and cause management overhead as application changes. Oracle GoldenGate's log-based change data capture is not only low-impact in terms of CPU utilization, but also non-intrusive to the application with low maintenance requirements.

8) Are there any customers in the manufacturing industry using GoldenGate and for which application?

We have many references in manufacturing. In fact, SolarWorld USA was our guest speaker in the executive video webcast last November. You can watch the interview here. RIM Blackberry uses Oracle GoldenGate for multi-master replication between its global manufacturing systems. Here is another manufacturing customer story from AkzoNobel.

9) Does GoldenGate 12c support compressed objects for replication? Also does it supports BLOB/CLOB columns?

Yes, GoldenGate 12c and GoldenGate 11gR2 both support compressed objects. GoldenGate has been supporting BLOB/CLOB columns since version 10.

10) Is Oracle Database 11.2.0.4 mandatory to use GoldenGate 12c Integrated Delivery? Not earlier versions?

Yes. To use GoldenGate 12c’s Integrated Delivery, for the target environment Oracle Database 11.2.04 and above is required .

11) We have Oracle Streams implementation for more than 5 years. We would like to migrate to GoldenGate, however older version of GoldenGate were not supporting filtering individual transactions. Is it supported in GoldenGate 12c?

      Yes, it is supported in GoldenGate 12c.


In future blog posts I will continue to provide answers for common questions we received in the webcast. In the meanwhile I highly recommend watching the Introducing Oracle GoldenGate 12c: Extreme Performance Simplified webcast on demand.

Oracle GoldenGate 12c - Leading Enterprise Replication

Oracle GoldenGate 12c released  on October 17th and includes several new cutting edge features that firmly establishes GoldenGate's leader position in the data replication space.   In fact, this release more than doubles the performance of data delivery, supports Oracle's new multitenant database feature,  it's more secure, has more options for high availability, and has made great strides to simplify the configuration and deployment of the product.     Read through the press release if you haven't already and do not miss the quote from Cern's Eva Dafonte Perez, regarding Oracle GoldenGate 12c "….performs five times faster compared to previous GoldenGate versions and simplifies the management of a multi-tier environment"

There are a variety of new and improved features in the Oracle GoldenGate 12c.  Here are the highlights:

  • Optimized for Oracle Database 12c -  GoldenGate 12c is custom tailored to the unique capabilities of Oracle database 12c and out of the box GoldenGate 12c supports multitenant (pluggable database (PDB)) and non-consolidated deployments of Oracle Database 12c.   The naming convention used by database 12c is now in three parts (PDB-name, schema-name, and object name).  We have made changes to the GoldenGate capture process to support the new naming convention and streamlined the whole process so a single GoldenGate capture process is being used at the container level rather than at each individual PDB.  By having the capture process at the container level resource usage and the number of processes are reduced. To view a conceptual architecture diagram click here.
  • Integrated Delivery for the Oracle Database - Leveraging a lightweight streaming API built exclusively for Oracle GoldenGate 12c, this process distributes load, auto tunes the degree of parallelism, scales better, and delivers blinding rates of changed data delivery to the Oracle database.  One of the goals for Oracle GoldenGate 12c was to reduce IT costs by simplifying the configuration and reduce the time to manage complex infrastructures.  In previous versions of Oracle GoldenGate, customers would split transaction loads by grouping tables into multiple different delivery processes (click here to view the previous method). Each delivery process executed independently and without any interaction or knowledge of other delivery processes.  This setup was complicated to configure and time consuming as the developer needed in-depth knowledge of the source and target schemas and the transaction profile. With GoldenGate 12c and Integrated Delivery we have made it easier to configure and faster to deploy.  To view a conceptual architecture diagram of integrated delivery click here
  • Coordinated Delivery for Non-Oracle Databases - Coordinated Delivery orchestrates high-speed apply processes and simplifies the configuration of GoldenGate for non-Oracle targets. In Oracle GoldenGate 12c a single delivery process is used with multiple threads (click here) and key events, such as primary key updates, event markers, DDL, etc, are coordinated between the various threads to insure that the transactions are applied in the same sequence as they were captured, all while delivery improved performance. 
  • Replication Between On-Premises and Cloud-Based systems. - The trend for business to utilize both on-premises and cloud-based systems is rising and businesses need to replicate data back and forth.   GoldenGate 12c can be configured in a variety of ways to provide real-time replication when unrestricted or restricted (limited ports or HTTP tunneling) networks are between on-premises and cloud-based systems.   

  • Expanded Heterogeneity - It wouldn't be a GoldenGate release without new and improved platform support.   Release 1 includes support for MySQL 5.6 and Sybase 15.7.   Upcoming in the next release GoldenGate, support will be expanded for MS SQL Server, DB2, and Teradata.
  • Tighter Security - Oracle GoldenGate 12c is integrated with the Oracle wallet to shield usernames and passwords using strong encryption and aliases.   Customers accustomed to using the Oracle Wallet with other Oracle products will instantly be familiar with how to use this great new feature
  • Expanded Oracle Application and Technology Support -   GoldenGate can be used along with Oracle Coherence to enable real-time changed data feeds to the Coherence cache using Toplink and the Oracle GoldenGate JMS adapter.     Plus,  Oracle Advanced Customer Services (ACS) now offers a low downtime E-Business Suite platform and database migrations using GoldenGate as the enabling technology. 

Keep tuned for more blogs on the new features and the upcoming launch webcast where we will go into these new features in more detail.   In the mean time make sure to read through our white paper "Oracle GoldenGate 12c Release 1 New Features Overview"

Oracle GoldenGate AppAdvantage in Action at Land O’Lakes, Smuckers, and Veolia Water

On Tuesday at OpenWorld we had the honor to host a panel with GoldenGate customers: Land O’Lakes, Smuckers, and Veolia Water. Besides giving us yummy nutrition and healthy water, these companies have another aspect in common. They all use GoldenGate to boost their ERP application.

Veoila Water’s Pierre Kerrinckx came from their HQ in France for this panel and spoke to us about the database migration project for their JD Edwards ERP system. Using GoldenGate Veolia was able to migrate from Oracle Database 10gR2 on Aix 5.3 Oracle 10g R2 to Oracle Database Aix 7.1 Oracle 11g R2 and did so with only 2 hours of interruption to JD Edwards end users. Pierre mentioned, the other benefit of GoldenGate was the ability to switch back to the old environment if needed.

Land O’Lakes’ Mark Kohls talked about their use of GoldenGate for their JD Edwards ERP system supporting the Purina business line. Land O’Lakes had to migrate enterprise-wide JDE Xe ERP system to new database and application server platform with minimal downtime to the business. While their goal was to have less than 8 hours of downtime, with GoldenGate they limited downtime to 30 minutes.

Both Veolia and Land O’Lakes used GoldenGate in an Active-Passive fashion, meaning that the new environment was not used simultaneously with the old one, and the users migrated all at once. GoldenGate provides Active-Active migration model too, if the company prefers to do a phased migration and truly zero downtime.

Smuckers's Neal Indermuhle had a different story to share. He talked about operational reporting for their critical Oracle E-Business Suite and how using Oracle GoldenGate helped the company to achieve the near real-time data they need in making critical business decisions. Neil shared that the replication latency averages less than 10 seconds and Oracle GoldenGate Veridata is leveraged to validate synchronization.

I would like to thank Pierre, Mark, and Neal for sharing their best practices, and taking tough questions from the audience. If you would like to learn more about Oracle GoldenGate’s solutions for JD Edwards, E-Business Suite and other key Oracle Applications please check out our new resource center with recorded video presentations and detailed white papers.

Before I get ready for another full day at OpenWorld tomorrow I would like to leave you with the key GoldenGate sessions we have lined up for Wednesday:

Maximum Availability with Oracle GoldenGate Webcast: On Demand Link & FAQ

Last month we had a live webcast on a hot topic: Maximum Availability with Oracle GoldenGate. The webcast presentation focused on how Oracle GoldenGate can help achieve maximum availability for Oracle Database and other major databases. This webcast was very useful in answering a frequently asked question around GoldenGate's role for Oracle Database Maximum Availability Architecture (MAA) and when to use Oracle GoldenGate vs Active Data Guard. Product experts, Joe Meeks from Oracle Database High Availability product management team and Nick Wagner from Oracle GoldenGate product management team, addressed this question for us. Joe and Nick presented GoldenGate’s key solutions within MAA, and when to use which product along with Integrated Capture and Automated Conflict Management features of GoldenGate 11gR2. If you missed this event I highly recommend watching it on demand via the following link.

Watch On Demand:Maximum Availability with Oracle GoldenGate.

We also recorded a short podcast on this topic. Oracle GoldenGate 11gR2 for Maximum Availability

In the live webcast we had a very interactive audience who submitted over 100 questions during the event. Joe and Nick answered the most commonly asked questions about GoldenGate’s use cases and technology. Here are a few of the questions that we did not have time to answer during the event, along with the answers from the PM team.

  • Can I use the target database as warehouse for select only. If I were to allow users to this target, are there steps to ensure both source and target databases remain in sync?

 Yes you can use the target for read only or select only operations. Yes, we can do bi-directional active-active replication if you want to allow users to make changes to the target system. We can replicate those back to the source.

  • Can Integrated Capture be run on Oracle Database Standard Edition?

Yes, but all of the features that are only supported by Integrated Capture are only available with Oracle Database Enterprise Edition.

  •  Is it possible to capture database transactions from a source database using GoldenGate and publish them as messages into   a JMS queue?

Yes, GoldenGate can capture from and deliver to JMS queue. Please see our page for Java Adapter for more info. 

  • Can GoldenGate be used in environments where a number of tables do not have primary keys?

Yes. In tables without primary keys, we will use all non-LOB columns in the where clause for updates and deletes and then use ROWNUM = 1.

  • Is there a webinar that shows how to set up Oracle GoldenGate?

 Oracle GoldenGate Youtube channels has many useful videos and labs including “Oracle GoldenGate Fundamentals and How Oracle GoldenGate Works” and “Oracle GoldenGate Deep Dive Hands-on Labs” in 3 part series. You can browse and watch them here. Please check out GoldenGate training sessions with Oracle University as well.

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

IT service continuity is a strategic goal for IT organizations, especially when it comes to mission-critical systems. A common interruption to IT services is planned outages such as system migrations, upgrades, consolidation etc. Because they can be planned, IT teams typically schedule them to "off business" hours to minimize impact on end users. 

What happens when you don't have long enough "off business hours" and need to upgrade your system to support the business? This issue comes up quite often with customers that have have critical systems with close to 24/7 up-time requirement and they decide to move to a new system such as Oracle Exadata. Exadata is a great fit for mission-critical systems with its extreme performance and reliability. When moving to this new, modern platform majority of companies have to plan carefully for the migration process with a focus on avoiding business interruption and minimizing the risks involved with the migration effort.

IQNavigator, the leading services procurement solution provider, is one of these many customers that needed a robust solution to eliminate downtime and minimize risks when moving to Exadata. The company chose Oracle GoldenGate to migrate to Oracle Exadata without downtime and with minimal risk. I am very happy to announce that next week we will be able to hear their story directly from IQNavigator's CEO of Emerging Markets and CTO, John F. Martin

  On December 15th 10am PT we will host a live webcast Zero Downtime Migration to Oracle Exadata Using Oracle GoldenGate: A Customer Case Study to share IQNavigator's implementation of GoldenGate for migrating to Exadata. Oracle's VP of Product Management/Development for Data Integration, Alok Pareek, will present about Oracle's real-time data integration offering for Oracle Exadata, as well.

    If you have plans to move to Oracle Exadata or have any other upgrade/migration project for your critical systems, I strongly recommend joining this webcast to learn how you can use GoldenGate for:

  • Real-time data replication between heterogeneous systems to eliminate downtime
  • Active-Active database synchronization for phased migration to minimize risk
  • Real-time data feeds into Oracle Exadata for reporting with timely information
  • Reliable real-time data synchronization for the standby system

To join this free & live webcast on December 15th you can register here.
