Geographically distributed multi-master MySQL clusters

https://www1.gotomeeting.com/register/601886553
Global data access can greatly expand the reach of your business. Continuent Tungsten multi-site multi-master (MSMM) solutions enable applications to accept write traffic in multiple locations across on-premises and cloud providers. This includes the following important real-world use cases:
  • Improve performance for globally distributed users registering hardware devices by permitting updates on the geographically closest site.
  • Ensure availability of credit card processing by spreading transaction processing across two or more sites. Users can still process credit card transactions if a single site is unavailable to them for any reason, including end-user Internet routing problems.
  • Enable business continuity by using multi-master updates on different hosting providers for service scalability, personalization and software upgrades of GPS devices.
Individual Continuent Tungsten clusters already provide excellent single-site database availability and performance. In this webinar we will review the benefits of combining multiple Continuent Tungsten clusters into a global multi-site multi-master topology for:
  • Optimizing your installation for MSMM
  • Optimizing your application for MSMM
  • Monitoring and administration
  • Failover and recovery of individual servers or entire locations.

Harnessing the power of master/slave clusters to operate data-driven businesses on MySQL

Users seeking high availability, DR and zero downtime maintenance operation for business-critical MySQL applications face confusing choices. Is multi-master or master/slave clustering better?  What about synchronous versus asynchronous replication? Using a plain vanilla, stock MySQL or a modified version of it? Which of these choices are right for data-driven businesses that depend on fast, reliable data access?

This no-BS webinar-on-demand cuts through the FUD to explore the real trade-offs between the different clustering and replication methods, then show you how Continuent Tungsten asynchronous master/slave clusters support these important capabilities for business-critical applications:

  • High application write rates
  • Mixed workloads consisting of large and small transactions
  • Data across multiple geographically distributed locations
  • Failures and more importantly recovery from them
  • Zero downtime maintenance and software upgrades
  • Use of off-the-shelf MySQL/MariaDB to avoid application changes and allow clusters to improve as MySQL itself does
We will illustrate key points with demonstrations and case studies from deployed systems.  Click here to view this educational session on the cutting edge of MySQL data management!

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.
