Active-Active Replication: Considerations for High Availability

As data becomes more and more critical, its availability should not be compromised by any type of outage – whether it’s unscheduled due to a system crash or malfunction, or it’s scheduled due to patches or upgrades to Oracle, the OS, or applications, and storage replacement. Because today, people view scheduled outages differently than 10 years ago. They don’t really care if the outage is scheduled or unscheduled; an outage is an outage. With this in mind, all types of organizations are looking for more uptime: many are striving for five 9s, or only about 6 minutes of unscheduled downtime a year. This is, of course, very difficult to achieve.

With replication, organizations can extend the database and server to minimize outages. One replication method, active- active replication (also known as peer-to-peer, master-to-master, active-active, or multi-active server replication), offers the most promise. Active-active replication is a horizontal scaling of the application over multiple servers that allows propagation of changes to more than one server. If everything is done properly, end users will not see any outages from the application.

This white paper discusses the key considerations to keep in mind when using active-active replication to ensure high availability. We’ll reveal how you can easily and successfully implement this strategy across your enterprise.

Zero impact database migration

Migrating data from one platform to another requires a lot of planning. Some traditional migration methods are easy to use, but they only work for migrations on the same platform. Quest® SharePlex® can replicate data across platforms, from Oracle to SQL Server, with next to no downtime, offering a flexible, low- cost alternative.

The SharePlex architecture is composed of a series of queues and processes running on the database servers that move data rapidly from the source database to the target database, without using Oracle’s processes or memory structures. This architecture facilitates the fault tolerance capability in SharePlex, which avoids data loss if there is a break in the replication stream.

Download this solution brief to learn how businesses can count on high availability, migrate data with zero organizational risk, and integrate data in near real-time for reporting and insights.

SharePlex® Data Replication: Staying Afloat After Oracle Streams (formerly Meeting Your Data-Sharing Needs Now that Oracle Streams is Deprecated)

Now that Oracle has deprecated Streams, Oracle Database Advanced Replication and Change Data Capture in Oracle Database 12c, they want you to buy Oracle GoldenGate. But this replacement is extremely expensive and leaves you vulnerable to downtime.

What if you could replace Streams with an affordable alternative that doesn’t expose you to risk? With SharePlex® data replication, you get even more functionality to avoid downtime and data loss than GoldenGate provides – all for a fraction of the price. See how you can achieve high availability, improve database performance and more with a more powerful and cost-effective replacement for Streams.

Using Data Replication to Upgrade Your Oracle® Database with Minimal Downtime

As your organization works to lower costs, one initiative can make a major difference: a database migration. Migration to hardware that is less expensive to purchase and operate, migration to less costly operating systems and migration away from older versions of Oracle that may require expensive extended support contracts can save you a lot of money. But without the right approach, migrations can cause costly downtime and data loss.

What if you could move to more affordable platforms without any of the risk? With SharePlex® data replication, you can migrate to the database platform of your choice with zero downtime and zero data loss.

In this white paper, we will explore the types of migrations and their challenges as well as established best practices for ensuring success.

ROI Study of Financial Institution using Network Verification

The primary function of Forward Enterprise is to collect device configuration data from every network device, including state information that governs the active behavior of the device. Forward Enterprise can then model and anticipate the behavior of the entire network end-to-end, and report on potential vulnerabilities, policy violations or risk exposure.

The common identified process improvements we have seen at several large customers are:

  • Reduced time to trouble ticket resolution
  • Reduced time spent on audit related fixes and updates
  • Fewer, shorter and more reliable change windows or network updates

Read how this financial institution cut costs by leveraging network verification in trouble ticket resolution, audit-related fixes, and change window frequency.

Network Reassurance

Network verification is a new technology for managing network chaos and automating key IT tasks such as troubleshooting, compliance processes, audits and change windows. Verification has been used in other engineering disciplines, such as software and semiconductor design, but has never been viable for networking until recent breakthroughs that Forward Networks helped pioneer. Since 80-90% of large enterprises are looking to incorporate intent-based networking into their IT strategy in the next few years, now is the time to determine how a verification platform can fit into your architecture going forward, and which use cases will bring the most benefit for your organization.

Networking Guru’s Guide to Verification

Today, networks have become so large and complex, along with constant changes to accommodate new services and business requirements, that networking teams can no longer document or manage all the details end-to-end. With potentially tens of thousands of devices and billions of lines of code, until now there has been no way to automate the analysis of network designs to quickly verify what devices you have, how they’re connected, where traffic goes, whether it’s really working, or what needs to change. Network verification is a rapidly emerging technology that provides deep insight to network behavior end-to-end, as well as automating many network troubleshooting and remediation tasks. Organizations are leveraging verification to help avoid outages, facilitate compliance processes and accelerate change windows.

Why Network Verification Requires a Mathematical Model

Network verification is a rapidly emerging technology that is a key part of Intent-Based Networking (IBN). Verification can help avoid outages, facilitate compliance processes, and accelerate change windows. Full-feature verification solutions require an underlying mathematical model of network behavior to analyze and reason about policy objectives and network designs. A mathematical model, as opposed to monitoring or testing live traffic, can perform exhaustive and definitive analysis of network implementations and behavior, including proving network isolation or security rules.

In this paper, we will describe how verification can be used in key IT processes and workflows, why a mathematical model is required and how it works, as well as example use cases from the Forward Enterprise platform. This will also clarify what requirements a mathematical model must meet and how to evaluate alternative products.

The Case for End-To-End Security Solutions For Mid-Market Firms

In a digital business, processes are rarely, if ever, confined to the infrastructure of the company. Customers and employees engage across numerous digital channels and dozens of third-party relationships critical to operations. IT leaders must rapidly evolve to protect their firms’ brands, strengthen their reputations, and build customer trust. To do so, security and productivity should go hand-in-hand, and that means a well-defined policy framework, metrics that demonstrate business value, and a business-aligned strategy that ties all this together.

The Balanced Security Imperative

Balanced security requires firms to transition from treating privacy and data security as compliance requirements to one that champions privacy and uses its technology prowess to differentiate the brand. Any misstep with or changes to the IT infrastructure can and will exacerbate complexity, which is why building a balanced security strategy is so important. A balanced security strategy negates complexity by keeping up with the pace of technological change as well as industry disruption and evolving regulatory compliance. In March 2019, Dell commissioned Forrester Consulting to evaluate the evolving security trends and technology needed to protect and enable employees. Our study found that empowering employees while adhering to security protocols improves employee productivity. Forrester conducted an online survey of 887 senior business and IT decision makers to explore this topic.

Managing Security Risk And Compliance In A Challenging Landscape (updated)

Security leaders have been in front of boards and executive committees long enough to know that security metrics that simply portray statistics from monitoring tools, or count the number of malware attacks, add relatively little value to strategy and budget decisions. Protecting sensitive customer and company data shouldn’t be just a compliance obligation, it should be a business imperative. This is exactly why the right technology partners will help push security, risk, and compliance objectives forward. In March 2019, Dell commissioned Forrester Consulting to evaluate the evolving security trends and technology needed to protect and enable employees.
