Webinar-on-Demand: Set Up & Operate Open Source Oracle Replication

Oracle's expensive and complex replication makes it difficult to build cost-effective applications that move data in real-time to data warehouses (Oracle, Hadoop, Vertica) and popular databases like MySQL. Fortunately, Continuent Tungsten offers a solution.

In this virtual course, you will learn how Continuent Tungsten solves problems with Oracle replication at a fraction of the cost of other solutions and with less management overhead too – think "Oracle GoldenGate without the price tag!"

Course Topics:

  • Tungsten Replicator installation and configuration
  • Provisioning existing schema and tables from Oracle into another server
  • Replicating between Oracle schemas
  • Replicating from Oracle to MySQL and data warehouses
  • Tips for solving common problems and improving performance
The course will include live demos to illustrate the operation. By the end of the course you will be ready move ahead with your own deployment.

Webinar-on-demand: Set up & operate real-time data loading into Hadoop


Getting data into Hadoop is not difficult, but it is complex if you want to load 'live' or semi-live data into your Hadoop cluster from your Oracle and MySQL databases. There are plenty of solutions available, from manually dumping and loading to the good and bad sides of using a tool like Sqoop. Neither are easy and both prone to the problems of lag between the moment you perform the dump and the load into Hadoop.

Replicating into Hadoop with Tungsten Replicator enables you to stream replication data from your Oracle and MySQL servers straight into Hadoop. Using the leading replication service built into Tungsten Replicator, and supporting all the topology and reliability features of Tungsten Replicator, the Hadoop applier enables you to replicate data directly from Oracle and MySQL into Hadoop.

In this virtual course, we'll look at the existing methods of loading Hadoop data, review how the Hadoop replicator works, and give a live demo of replicating data from MySQL into Hadoop. Replicate from Oracle and MySQL to Hadoop.

Continuent Tungsten 2.0.2 Release Notification

www.continuent.com/softwareWe are pleased to inform you that the new Continuent Tungsten 2.0.2 is now available. Continuent Tungsten keeps data available to applications 7x24 through hardware failures, maintenance, and software upgrades. It ensures business continuity and performance by keeping up-to-date data closer to the user, and increases application throughput and improves response time by load balancing SQL transactions across replicas.

New Continuent Tungsten 2.0.2 includes:

  • Significant stability improvements to the manager service
  • Improvements to the memory management and failure handling
  • Updates to the embedded JGroups service to improve service and communication stability
  • All of the new features and improvements from Tungsten Replicator 2.2.1, including automatic recovery for the replicator in the event of minor transient errors, improved command-line tools for THL and slave provision, and improved support for Oracle deployments.
For a complete listing of new features and improvements in Continuent Tungsten 2.0.2, see release notes.

Upgrading to the 2.0.2 release:

Set Up & Operate Tungsten Clusters

In this virtual course, you will learn how to get from a single database server to a scalable cluster, or from a brittle MySQL replication system to a transparent, manageable Continuent Tungsten cluster. 

We discuss the benefits of leveraging Continuent Tungsten clustering with MySQL, and walk you through the steps to implement a Continuent Tungsten cluster in Amazon EC2. We cover the prerequisites, installing and configuring Continuent Tungsten, and best practices that are part of most production installations and proof-of-concepts.

Course Topics:

  • Configuring MySQL and the OS for a proper Continuent Tungsten installation
  • Installing a cross-site Continuent Tungsten cluster
  • Online maintenance by performing a schema upgrade on the master database server with no application downtime (switch operation)
  • Automatic master failover upon a MySQL database server failure
  • Recovery of a failed master to a fully operational cluster member with a single command (recover operation)
  • Disaster recovery by switching database operations to another data center or AWS region (geo-clustering, cross-site 'switch' operation)
  • Multi-master operations across multiple geographic regions
We also discuss and demonstrate basic operations, such as adding and removing a cluster node, basic monitoring and troubleshooting, and discuss the basic failure scenarios.

Learn how to quickly configure and provision highly optimized Continuent Tungsten deployments in the cloud or on-premises.
