Disaster Recovery Jackpot: Active/Active WAN-based Replication in GemFire vs Oracle and MySQL

Ensuring your systems run smooth even when your data center has a hiccup, or a real disaster strikes is critical for many companies to survive when hardships befall them.  As we enter the age of the zettabyte, seamless disaster recovery has become even more critical and difficult. There is more data than we have ever handled before, and most of it is very, very big.

Most disaster recovery (DR) sites are in standby mode—assets sitting idle, waiting for their turn. The sites are either holding data copied through a storage area network (SAN) or using other data replication mechanisms to propagate information from a live site to a standby site.  When disaster strikes, clients are redirected to the standby site where they’re greeted with a polite “please wait” while the site spins up.

At best, the DR site is a hot standby that is ready to go on short notice.  DNS redirects clients to the DR site and they’re good to go.

What about all the machines at the DR site?  With active/passive replication you can probably do queries on the slave site, but what if you want to make full use of all of that expensive gear and go active/active?  The challenge is in the data replication technology. Most current data replication architectures are one-way. If it’s not one-way, it can come with restrictions—for example, you need to avoid opening files with exclusive access.

Scaling and Modernizing .NET and Java: SQLFire Performance Test Blows Away Traditional RDBMS

We all know the devil is in the details when it comes to technology.

Yet, our recent vFabric SQLFire performance test (a benchmark from vFabric SQLFire Best Practices Guide) is certainly worth review if you need to scale a Java app, .NET app, or other legacy data source.

If you don’t know what vFabric SQLFire is, it is basically what happens when Apache Derby gets married to vFabric GemFire:

  • Apache Derby is used for its RDBMS components, JDBC driver, query engine, and network server.
  • The partitioning technology of GemFire is used to implement horizontal partitioning features of vFabric SQLFire.
  • vFabric SQLFire specifically enhances the Apache Derby components, such as the query engine, the SQL interface, data persistence, and data eviction, as well as adding additional components like SQL commands, stored procedures, system tables, functions, persistence disk stores, listeners, and locators, to operate a highly distributed and fault tolerant data management cluster.

How to Prepare for a Hyperic 5.0 Upgrade

Recently, we announced a new version of our popular web infrastructure management tool, Hyperic 5.0.  We also explained how, in this new version, the backend data store is moving to support PostgreSQL. In this article, we are providing existing Hyperic users the information they need to plan their upgrade to Hyperic 5.0. This article is for anyone already running Hyperic HQ (open source), vFabric Hyperic, vFabric Application Performance Manager, or vCenter Operations Manager.

This post is meant to augment the knowledge base article, KB 2033940, published back in August.

Planning the Upgrade

We know platform changes can make an upgrade more difficult and certainly raise eyebrows. So, we’ve taken measures to help make the migration as seamless and simple as possible. So far, the cases we’ve seen take about an hour. As with any data migration, the greater the volume of database records, the longer it can take. Continue reading

Solving the Learning Curve: How VMware Accelerates IT Service Delivery Yet Again

Have you ever been asked to get a new application environment up and ready for a new initiative and been told, “this really should have been done yesterday”? Usually when this happens, the application they are looking for requires some technology you know nothing about, like an Oracle WebLogic Server. Of course, just to stress matters more, you do not have any WebLogic subject matter experts in-house to help you out. So, you are stuck with cryptic installation docs and maybe a useful YouTube video or two. Wouldn’t it be great if you could leverage a website that was similar to Apple’s App Store? A marketplace where you can download and deploy that environment at the click of a button, and avoid the whole learning curve of setting it up? As a bonus, you can trust that the WebLogic server you are deploying was set up by subject matter expert whose optimized the setup already to run in the cloud? If that existed, your job in IT would be a lot easier, right?

As of this month, your job can be that easy. On December 3rd, VMware announced the VMware Cloud Application Marketplace as part of the VMware Solution Exchange. The Cloud Application Marketplace provides easy access to best practice application components, services, and even complete blueprints for cloud-ready solutions that can be deployed to any cloud using vFabric Application Director.

With over 30 software vendors, system integrators, and cloud providers like Oracle, Microsoft, Riverbed, and Accenture already on board, your IT department has access to over 100 real world applications you can rapidly deploy, monitor and scale in public, private and hybrid cloud infrastructures.

Why Hyperic is Going to Support PostgreSQL Only As a Backend Database

The next release of Hyperic is coming up soon and the biggest change is to the backend. In the next release, we will only support one database, namely PostgreSQL. Those of you who have been with Hyperic for a while as long as I have may be surprised considering our history with PostgreSQL, but, as you read though this blog, it will start to make sense.

History of PostgreSQL and Hyperic

For the last few years Hyperic has supported only two databases for production use at scale—Oracle and MySQL. This in itself was a big change since at one point, PostgreSQL was our bread and butter.  Hyperic was originally designed on PostgreSQL 7.x. As an open source project, PostgreSQL has a very easy license for distribution. As a startup company we had to get our product out into the marketplace quickly and affordably, so therefore PostgreSQL made sense.

vFabric Data Director supports Oracle, SQL Server, Hadoop, Postgres – Accelerates database virtualization and Big Data adoption

Virtualization continues to be one of the top priorities for CIOs. As the share of virtualized workloads approaches 60%, the enterprise is looking at database and big data workloads as the next target. Their goal is to realize the virtualization benefits with the plethora of relational database sprawling in their data centers. With the increasing popularity of analytic workloads on Hadoop, virtualization presents a fast and efficient way to get started with existing infrastructure, and scale the data dynamically as needed.

VMware’s vFabric Data Director 2.5 now extends the benefits of virtualization to both traditional relational databases like Oracle, SQL Server and Postgres as well as Big Data, multi-node data solutions like Hadoop. SQL Server and Oracle represent the majority of databases in enterprises, and, Hadoop is the one of the fastest growing data technologies in the enterprise.

vFabric Data Director enables the most common databases found in the enterprise to be delivered as a service with the agility of public cloud and enterprise-grade security and control.

The key new features in vFabric Data Director 2.5 are:

  • Support for SQL Server – Currently supported versions of SQL Server are 2008 R2 and 2012.
  • Support for Apache Hadoop 1.0-based distributions: Apache Hadoop 1.0, Cloudera CDH3, Greenplum HD 1.1, 1.2 and Hortonworks HDP-1. Data Director leverages VMware’s open source Project Serengeti to deliver this capability.
  • Streamlined Data Director Setup – Complete setup in in less than an hour
  • One-click template creation for Oracle and SQL Server through ISO based database and OS installation
  • Oracle database ingestion enhancements – Now includes Point In Time Refresh (PITR)

Data Director’s self-provisioning enables a whole new level of operational efficiencies that greatly accelerates application development. With this new release, Data Director now delivers these efficiencies in a heterogeneous database environment.

The VMware vFabric team is going to Oracle Open World next week in San Francisco.  Starting on Monday, Sept 30th and going to Wednesday, October 2, there are three places you should look for us:

1. Stop by our booth at 1733 Moscone South – right near the Oracle DEMOgrounds where you can learn about several VMware technologies related to Oracle:

Why DBaaS? 5 Trends Pushing Database as a Service

What if you could provision a highly available, compliant database in one click? For many, this sounds impossible…particularly behind the firewall. Yet, it is possible today because database management has changed.

The change has been driven by years, perhaps decades, of unmet needs. For example, we’ve all heard these types of comments made inside our respective companies:

  1. “Could we have a temporary copy of the database to use for a few days?”
  2. “We can finish faster doing it ourselves with a PC under someone’s desk.”
  3. “Didn’t we just buy a bunch of new database licenses?”
  4. “I have to test this with production data.”
  5. “It would be crazy to put two databases on the same server.
