Oracle GoldenGate for Big Data 12.2.0.1 is Generally Available Now!

Much awaited Oracle GoldenGate for Big Data 12.2 is released today and it is available for download at OTN.

Let me give you a quick recap on Oracle GoldenGate for Big Data. Oracle GoldenGate for Big Data streams transactional data into big data systems in real-time, raising the quality and timeliness of business insights. Oracle GoldenGate for Big Data offers also provides a flexible and extensible solution to support all major big data systems.

Oracle GoldenGate for Big Data

  • Same trusted Oracle GoldenGate architecture used by 1000’s of customers
  • Data delivery to Big Data targets including NoSQL databases
  • Support for Polyglot, Lambda and Kappa architectures for streaming data

Key Benefits

  • Less invasive on source databases when compared to batch processing such as Sqoop or ETL processes
  • Simple ingestion for 1:1 data architecture for populating “raw data” zones
  • Real-time data delivery for streaming analytics/apps
  • Reliable, proven at scale with high performance


Architecture – GoldenGate for Big Data 12.2 versus 12.1

New Features in 12.2.0.1:



New Java based Replicat Process 

The advantages of using Java based Replicat process are the following:

    1. Improved performance with Java based adapters
    2. Declarative design and configurable mapping
    3. Transaction grouping based on Operation count & Message size
    4. Improved check pointing functionality
      E.g.: CHECKPOINTSECS 1 (default 10 seconds)

Dynamic Data Handling

You no longer require to define SOURCEDEFS. DDL changes are automatically replicated to target. For example, if a new column named “mycolumn“ is added on the source database, it will be automatically replicated to the target without stopping and reconfiguring Oracle GoldenGate.

Pluggable Formatters

Oracle GoldenGate for Big Data can write into any Big Data targets in various data formats such as delimited text or XML or JSON or Avro or custom format. This can save users cost and time for staging data in ETL operations.

Example: gg.handler.name.format= <value>
values supported are delimitedtext”, “xml”, “json”, “avro” or “avro_row”, “avro_op” or Custom Format. Extended class path needs to be included in the config file. <com.yourcompany.YourFormatter

Security Enhancement

Native Kerberos support is available in the 12.2.0.1 binaries.

Example of configuration:
gg.handler.gghdfs.authType=Kerberos
gg.handler.gghdfs.kerberosKeytabFile=/keytab/file/path
gg.handler.gghdfs.kerberosPrincipal=user/FQDN@MY.REALM

Declarative Design

Oracle GoldenGate for Big Data is able to provide mapping functionally between source table to target table and source field to target field for HDFS/Hive, HBase, Flume and Kafka. The metadata is also validated at Hive or using an Avro schema to ensure data correctness.

Example:
MAP GG.TCUSTOMER, TARGET GG.TCUSTMER2, COLMAP (USEDEFAULTS, "cust_code2"=cust_code,"city2"=city);

Kafka as target

Oracle GoldenGate for Big Data can write Logical change records data to a Kafka topic. Operations such as Insert, Update, Delete and Primary Key Update can be handled. It can handles native compression such as GZIP and Snappy in Kafka.

Example of defining Kafka Handler Properties:
gg.handlerlist=ggkafka
gg.handler.ggkafka.type=kafka
gg.handler.ggkafka.topicName=gg_kafka
gg.handler.ggkafka.mode=tx

Other Enhancements

  • Partition data by Hive Table and/or column. Partitioning into new file based on designated column values
    Example:
    • gg.handler.{name}.partitionByTable =true | false
    • gg.handler.{name}.partitioner.{fully qualified table name}={colname}
    • gg.handler.{name}.partitioner.{fully qualified table name}={colname1},{colname2}
    • gg.handler.<yourhandlername>.partitioner.dbo.TCUSTORD=region, rating
  • Configurable File Rolling Property for HDFS (file size, duration, inactivity timer, metadata change)
  • Configurable file output encoding into HDFS
  • Automatically create HBase table if it does not exist
  • Ability to treat primary key updates as a delete and then an insert in HBase
  • HBase row key generation
  • Treat Primary Key updates as delete and insert in Flume and HBase
  • New Time stamping functionality to include micro second precision as ISO-8601
  • Availability on additional OS platforms: Windows and Solaris
  • Certification for newer versions: Apache HDFS 2.7.x, Cloudera 5.4.x, Hortonworks 2.3, Kafka 0.8.2.0 and 0.8.2.1

Recap of Oracle GoldenGate 12c for the Enterprise and the Cloud webcast

Last week I hosted a webcast on Oracle GoldenGate 12c's latest features and its solutions for cloud environments. For those of you who missed it, I wanted to give a quick recap and remind that you can watch it on-demand via the following link:

Oracle GoldenGate 12c for the Enterprise and the Cloud

In this webcast my colleague Chai Pydimukkala, senior director of product management for Oracle GoldenGate and I talked about some of the key challenges in cloud deployments and how Oracle GoldenGate addresses them. We discussed examples of cloud-specific data integration use cases, such as synchronizing data between on-premises systems and Oracle Cloud or Amazon Cloud environments. We also discussed zero downtime consolidation to cloud using Oracle GoldenGate.

In the webcast, Chai also presented  the latest features of Oracle GoldenGate 12.1.x including:

  • New database support, including Informix, SQL Server 2014, MySQL Community Edition
  • Real-time data integration between on-premises and cloud with SOCKS5 compliance
  • New features in Oracle GoldenGate Veridata especially the new data repair capabilities
  • Enhancements to Integrated Delivery, and support for capturing data from Active Data Guard standby system
  • The new migration utility to help with the move from Oracle Streams to Oracle GoldenGate.
As with previous GoldenGate webcasts we had a very interactive Q&A where we received tons of questions. We tried answer as much as possible in the available time but could not get to all of them.  Below are some of the commonly asked questions we received during the webcast and brief answers:

Question: Does GoldenGate replace ODI? When shall we use an ETL tool vs GoldenGate?

Answer: GoldenGate is designed for real-time, change data capture, routing, and delivery. It  performs basic, row level transformations. For complex transformation requirements you still need ETL/E-LT solutions. Our customers augment their existing ETL/E-LT solutions by adding GoldenGate for real-time, low-impact change data capture and delivery. GoldenGate can deliver data for ETL in flat file format, or feed staging tables, or it can be JMS messages.Oracle Data Integrator's E-LT architecture creates perfect combination as GoldenGate can capture changed data non-intrusively with low-impact, and deliver to staging tables in the target with sub-seconds latency. With ability to perform transformations within the target (or source) database, ODI takes this change data, performs transformations in micro-batches and loads user tables with high performance. Because of this natural and strategic fit between the products, we have tightly integrated ODI and GoldenGate.To learn more about how GoldenGate and ODI are integrated and work together, please watch this on-demand webcast. I also recommend reading the following white paper on real-time data warehousing best practices

Here you can see a demo of ODI and for customer examples, you can watch Paychex , RBS, and Raymond James videos.

Question: Is there a plan to sell GoldenGate as a service soon?

Answer: Yes, it is in the plans. We are working with the Oracle Cloud team. But we are not able to give a timeline.

Question: Are Integrated Capture and Delivery only available for Oracle Database or this can be used for non-Oracle databases?

Answer: Integrated Capture and Delivery are only available for Oracle Database and truly differentiate Oracle GoldenGate against other data integration and replication vendors. We offer Coordinated Delivery for all supported databases. Coordinated Delivery simplifies configuration significantly as well and it works with non-Oracle databases too. You can read more about Coordinated Delivery in a related blog,  via Oracle GoldenGate 12c Release 1 New Features Overview white paper or documentation.

Question: Is GoldenGate available for download for trial?

Answer: Yes, you can download GoldenGate on OTN for education and development purposes: http://www.oracle.com/technetwork/middleware/goldengate/downloads/index.html.  For big data use case, you can use Big Data Lite virtual environment to experiment with Oracle GoldenGate. 

Question: Does GoldenGate replace Active Data Guard? 

 No. The products are complementary. Data Guard is a physical replication solution designed for Oracle Database disaster recovery and offers it with great simplicity and performance. Oracle GoldenGate offers logical/transactional data replication which supplements Active Data Guard by eliminating downtime during planned outages (migration, consolidation, maintenance), and active-active data center synchronization for maximum availability. License for Oracle GoldenGate for Oracle Database includes also Active Data Guard. As mentioned in the webcast, GoldenGate 12c now can capture data from Active Data Guard's standby system too.

Question:  Does the GoldenGate Veridata repair subset of data instead of doing full sync ? Example : I want to repair only missed deletes.

Yes. Oracle GoldenGate Veridata can do granular repair for out-of-sync records. Please see our Oracle GoldenGate Veridata data sheet for more info.

Question: How do we use Enterprise Manager for GoldenGate? 

Answer: Oracle Management Pack for Oracle GoldenGate license includes a Enterprise Manager Plug-in that allows you to use your Oracle Enterprise Manager solution to monitor and manage Oracle GoldenGate solutions. 

If you have not attended the webcast live, I highly recommend watching Oracle GoldenGate 12c for the Enterprise and the Cloud on demand and listening to the long Q&A session with Chai. During the webcast we covered many other frequently asked questions.

Oracle Data Integration Continues to Shine on Oracle Exadata

In previous posts I have shared with you how Oracle offers the best data integration for Oracle Exadata. Oracle’s key differentiation in providing solutions that are engineered to work together, applies to the critical add-on technologies such as data integration and replication as well. Our customers’ successes with using Oracle GoldenGate and Oracle Data Integrator is a continuous flow of confirmation that Oracle’s differentiated offering brings real results, simplifies IT, and enables innovation.

Today, I have two brand new customer examples to share with you. 11ST uses Oracle GoldenGate for real-time data integration into the data warehouse, and Abu Dhabi National Oil Company Distribution uses Oracle GoldenGate for achieving high availability for its private cloud environment running on Exadata.

  • 11ST is Korea’s largest online marketplace where customers and sellers can freely trade retail goods, ranging from clothing and food, to electronic equipment. With over 10x turnover growth over the last 4 years, the company faced challenges in delivering high speed transaction processing and good customer experience. So the company decided to implement Oracle Exadata for core database platform to accelerate data-processing speed for online transactions, and for the data warehouse to improve analytical capabilities with a solution that can handle intensive analytical workloads in a scalable fashion.With Exadata, the company increased storage capacity by up to 5x and decreased storage costs, while improving customer satisfaction by accelerating data-processing speed for online transactions.
11ST chose Oracle GoldenGate as the real-time data integration solution for the data warehouse running on Exadata. Their goal is to enable staff access to more timely data throughout the day such as online sales tracking and earnings by period. Oracle GoldenGate supports fast decision-making by completing daily batch loads 4.5x faster—in two hours instead of nine hours.

The key business transformation is seen in their customers’ experience. With the availability of real-time data synchronization between the enterprise data warehouse and marketing systems, the company can act fast to changing customer tastes, such as for women’s clothing and jewelry, to improve its offering and customer service. Using timely data and advanced analytics, the company runs personalized marketing programs, such as cosmetics or shoe promotions, through mobile, private-brand services, which was not possible with the legacy system. You can read more about 11ST story here.

Especially for data warehousing solutions many customers leverage the comprehensive and integrated Oracle Data Integration platform for Exadata. Below is a diagram that shows how customers can achieve an end-to-end solution.

Avea,and Paychex are ywo other good examples of using Oracle Data Integration for Exadata environments for improved analytical capabilities.

  • Abu Dhabi National Oil Company Distribution (ADNOC Distribution) is a United Arab Emirates (UAE) government-owned company that specializes in marketing and distributing petroleum products within the country. The organization decided to implement Oracle Exadata Database Machine to consolidate five Oracle Databases—supporting enterprise resource planning (ERP), online transaction processing (OLTP) applications, and business intelligence (BI) applications—onto a single database platform within a private database cloud.

As this private cloud environment supports the backbone of a business with 250 million financial transactions annually, ADNOC Distribution cannot afford even a minute's downtime. To ensure 24/7 uptime and meet service-level agreements, the company uses Oracle Exadata with Oracle Real Application Clusters and Oracle Automatic Storage Management. Using Oracle GoldenGate ADNOC maximized system availability and improved its ability to integrate Oracle Exadata with nonOracle platforms, such as Microsoft SQL or IBM DB2. You can read more about 11ST story here.

 In a recent webcast we discussed Oracle GoldenGate's offering for consolidation into private cloud. I also recommend watching the webcast: Zero Downtime Consolidation to Oracle Database 12c with Oracle GoldenGate 12c on demand to learn how to use Oracle GoldenGate for maximizing availability in private cloud environments.

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.

What's New in Oracle GoldenGate 12c for DB2 iSeries

Oracle GoldenGate 12c (12.1.2.0.1) for IBM DB2 iSeries was released on February 15, 2014. The new version delivers the following new features: 

  • Native Delivery (Replicat): the new feature allows the user to install Oracle GoldenGate on the IBM i server and delivers the data directly to the IBM DB2 for i database. In previous releases, users had to install Oracle GoldenGate on a remote server and apply the data to the IBM DB2 for i database via ODBC. The native delivery not only improves the performance but also supports the GRAPHIC, VARGRAPHIC and DBCLOB datatypes, which are not supported in the ODBC remote delivery for IBM DB2 for i. 
  • Schema Wildcarding: as with other databases that Oracle GoldenGate supports, the schema wildcarding is now available for the IBM DB2 for i database as well.
  • Auto discard: the discard file is now created by default. 
  • Coordinated Delivery (Replicat):  the coordinated delivery is supported in the native delivery (replicat). 
  • BATCHSQL: supported on IBM i 7.1 and higher version.
