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.

Monitoring Oracle GoldenGate 11g Release 2

One of the key improvements in Oracle GoldenGate 11g Release 2 is in the monitoring area. This release brought  integration with Oracle Enterprise Manager 12c, as well as a new product dedicated for monitoring Oracle GoldenGate, called Oracle GoldenGate Monitor.  This new product is included in the Management Pack for Oracle GoldenGate and offers GUI-based solution for end-to-end, real-time visibility into Oracle GoldenGate implementations across the enterprise. GoldenGate Monitor increases IT productivity by offering consolidated information for multiple instances of Oracle GoldenGate and via its comprehensive e-mail, SNMP and CLI alert capabilities, among many other features.

We have a new screencast that presents Oracle GoldenGate  Monitor's features and architecture, along with a product demonstration. If you have a GoldenGate solution or plan to deploy one, I highly recommend watching this screencast here or via the embedded video below to learn about monitoring GoldenGate processes via this simple but powerful GUI-based product.

Thank You for a Great Welcome for Oracle GoldenGate 11g Release 2

Yesterday morning we had two launch webcasts for Oracle GoldenGate 11g Release 2. I had the pleasure to present, as well as moderate the Q&A panels in both of these webcasts. Both events had hundreds of live attendees, sending us over 150 questions. Even though we left 30 minutes for Q&A, it was not nearly enough time to address for all the insightful questions our audience sent. Our product management team and I really appreciate the interaction we had yesterday and we are starting to respond back with outstanding questions today.

Oracle GoldenGate’s new release launch also had great welcome from the media. You can find the links for various articles on the new release below:

DBTA, Real-Time Data Integration: Oracle GoldenGate 11g Release 2 Now Available

CBR Oracle unveils GoldenGate 11g Release 2 real-time data integration application

In this blog, I want to address some of the frequently asked questions that came up during the webcasts. You can find the top questions and their answers along with related resources below. We will continue to address frequently asked questions via future blogs.

Q: Will the new Integrated Capture for Oracle Database replace the Classic Capture? If not, which one do I use when?

A: No, Classic Capture will be around for long time. Core platform specific features, bug fixes, and patches will be available for both Capture processes.Oracle Database specific features will be only available in the Integrated Capture. The Integrated Capture for Oracle Database is an option for users that need to capture data from compressed tables or need support for XML data types, XA on RAC. Users who don’t leverage these features should continue to use our Classic Capture.

For more information on Oracle GoldenGate 11g Release 2 I recommend to check out the White paper: Oracle GoldenGate 11gR2 New Features as well as other technical white papers we have on OTN.                                                        

For those of you coming to OpenWorld, please attend the related session:

Extracting Data in Oracle GoldenGate Integrated Capture Mode, Monday Oct 1st 1:45pm Moscone South – 102

to learn more about this new feature.

Q: What is new in Conflict Detection and Resolution? And how does it work?

A: There are now pre-built functions to identify the conditions under which an error occurs and how to handle the record when the condition occurs. Error conditions handled include inserts into a target table where the row already exists, updates or deletes to target table rows that exist, but the original source data (before columns) do not match the existing data in the target row, and updates or deletes where the row does not exist in the target database table.For
each of these conditions a method to handle the error is specified. 

Please check out our recent blog on this topic and the White paper: Oracle GoldenGate 11gR2 New Features white paper.

 Also, for those attending OpenWorld please attend the session:

Best Practices for Conflict Detection and Resolution in Oracle GoldenGate for Active/Active-  Wednesday Oct 3rd  3:30pm Mascone 3000

Q: Does Oracle GoldenGate Veridata and the Management Pack require additional licenses, or is it incorporated with the GoldenGate license?

A: Oracle GoldenGate Veridata and Oracle Management Pack for Oracle GoldenGate are additional products and require separate licenses. Please check out Oracle's price list here.

Q: Does GoldenGate - Oracle Enterprise Manager Plug-in require additional license?

A: Oracle Enterprise Manager Plug-in is included in the Oracle Management Pack for Oracle GoldenGate license, which is separate from Oracle GoldenGate license. There is no separate license for the Enterprise Manager Plug-in by itself. Oracle GoldenGate Monitor, Oracle GoldenGate Director, and Enterprise Manager Plug-in are included in the Management Pack for Oracle GoldenGate license. Please check out Management Pack for Oracle GoldenGate data sheet for more info on this product bundle.

Q: Is Oracle GoldenGate replacing Oracle Streams product?

A: Oracle GoldenGate is the strategic data replication product. Therefore, Oracle Streams will continue to be supported, but will not be actively enhanced. Rather, the best elements of Oracle Streams will be added to Oracle GoldenGate. Conflict management is one of them and with the latest release Oracle GoldenGate has a more advanced conflict management offering. Current customers depending on Oracle Streams will continue to be fully supported.

Q: How is Oracle GoldenGate different than Oracle Data Integrator?

A: Oracle Data Integrator is designed for fast bulk data movement and transformation between heterogeneous systems, while GoldenGate is designed for real-time movement of transactions between heterogeneous systems. These two products are completely complementary where GoldenGate provides low-impact real-time change data capture and delivery to a staging area on the target. And Oracle Data Integrator transforms this data and loads the DW tables. In fact, Oracle Data Integrator integrates with GoldenGate to use GoldenGate’s Capture process as one option for its CDC mechanism. We have several customers that deployed GoldenGate and ODI together to feed real-time data to their data warehousing solutions. Please also check out Oracle Data Integrator Changed Data Capture with Oracle GoldenGate Data Sheet (PDF).

Thank you again very much for welcoming Oracle GoldenGate 11g Release 2 and stay in touch with us for more exciting news, updates, and events.
