Oracle on Wednesday delivered a two-node Oracle Database 11g and Oracle lawful utility Clusters (RAC) paraphernalia that offers a lower cost entry point to Oracle Exadata, but it doesn’t encompass a lot of utility facets that supply Exadata performance boosts.
The 4U Intel-primarily based computer, known as the Oracle Database equipment, contains two servers with built-in shared storage that allows cease clients to construct a two-node Oracle RAC infrastructure. list charge begins at $50,000 for the hardware only, enormously lessen than the six-figure starting aspect of 1 / 4-rack Exadata. Oracle suggested it will travail with databases as much as 4 terabytes giant. Specs encompass:
24 total Intel Xeon processor cores
192 gigabytes main memory
12 terabytes raw disk storage; 292 gigabytes solid state storage
Scalable licensing per processing core from 2 to 24 cores
That talked about, the Oracle Database appliance doesn’t include the Oracle Exadata Storage Server utility aspects such as hybrid columnar compression and wise scan that the enterprise claims hold given Exadata exponential query improvements.
“Oracle basically needed some thing like this,” mentioned Alex Gorbachev, chief expertise officer (CTO) of Pythian, an Oracle consulting business that took half in the beta application for the brand current appliance. “lots of purchasers couldn’t justify the cost of Exadata but may employ some of the facets that an integrated paraphernalia can provide.”
It took Pythian “a couple hours” to installation the equipment, hold it working and accepting records on it. Gorbachev delivered that consistently a current gadget setup requires talents from a variety of IT departments: methods, storage, networking and database, as an instance. Configuring this current appliance doesn’t require that.
The paraphernalia additionally comes with some administration software that simplifies its operations and automates patching for instance.
“It nevertheless requires some feeding and trust when it involves tuning, however other than that it’s getting rid of lots of overhead.”
That doesn’t carry weight it's going to eliminate the need for a DBA.
Kerry Osborne, chief tips officer (CIO) at Enkitec, a different Oracle consultancy that had an early survey at the equipment, referred to cease users received’t score the selfsame efficiency that they'd score out of Oracle Exadata. and they shouldn’t predict it either: the brand current product is a smaller, less-costly version of Exadata, and as such it’s no longer going to hold as many features. Osborne talked about it’s additionally no longer anything that you could toss within the corner and expect to elope by itself.
“any individual that thinks that you would subsist able to elope any category of Oracle database without a educated person is asking for crisis,” he mentioned.
Shyam Varan Nath, probably the most founders of the Oracle Exadata special pastime community within the impartial Oracle clients community, spoke of that Oracle at the start had a eighth-rack Exadata however discontinued it. He considered Oracle’s response to these smaller IT stores that stated the quarter-rack Exadata became still too expensive.
“This may subsist a means to provide the selfsame box at reduce cost aspect without raising eyebrows on these already offered at higher expense factor as intended for significant companies,” he pointed out.

Because there’s so much excitement about the potential of blockchain, there’s a risk that project planners will start throwing this emerging technology at problems that don’t fit. This article is meant to uphold you sort out the right business employ cases for blockchain, from those for which your trusty database will result just fine.
First and foremost when considering blockchain, pick a project that needs “distributed” instead of centralized control of data, said Michael Onders, chief data officer of KeyBank, speaking at a panel discussion at the Blockland Cleveland event in December. “If you can decipher the problem centrally, using a central database, you’re probably looking at the wrong problem,” Onders said.
For example, KeyBank would like to view the state of Ohio create a blockchain with so-called smart contracts to manage auto titles, to track and record vehicle-ownership changes more efficiently.
Doing so would require the state, banks, insurance companies, dealers, and other parties to select partake in the blockchain, accessing, and providing data about vehicle ownership and insurance status changes. That’s the kind of distributed data control that makes a strong case for blockchain—and it’s a haphazard for Ohio to bespeak its leadership in an emerging tech realm, showing the country this can subsist done. “We would subsist jubilant to participate in that,” said, Onders, speaking at the Blockland Cleveland conference late final year.
Sarabjeet (Jay) Chugh, a senior director of emerging technology products at Oracle, likewise cautions enterprises against starting with the goal of finding a employ case for blockchain.
“Let’s not start with ‘I want to employ blockchain,’” Chugh says. “That may lead you to the wrong answer. You should hold a problem to decipher and then you should say, ‘What is the right mechanism to decipher it?’ It could subsist a relational database, it could subsist a distributed database, or it could subsist blockchain.”
3 Questions to Vet Your Blockchain Project
How result you conclude if blockchain fits your project? Generally, blockchain can uphold in situations where multiple parties need to maintain shared information, and where those parties may not completely trust each other. Or, to establish this in a gentler way, those parties travail together but don’t hold completely aligned interests—for example, manufacturers, shippers, and buyers tracking goods along a supply chain, where some parties might hold an incentive to fudge on when things were delivered—or, worst case, swap in counterfeit goods.
Blockchain may fit when you also don’t want to depend on one central party to store and validate transaction data, and you want a shared data source that can’t subsist easily altered or written over by any one participant without detection—an immutable ledger, in blockchain parlance. Multiple parties unite to contour a blockchain network that allows them to partake blockchain information among themselves. When data is updated—say, a delivery or change to an auto title is made—that change is added to the ledger as a current block and verified by parties involved through a consensus mechanism. Everyone on the network can view the changes. assume of an enterprise blockchain as executing transactions that track assets as they change hands among organizations—assets that can subsist tangible, such as physical goods or a contract document, or intangible, such as digital employ rights.
Once you hold a broad understanding of the problem you assume might profit from blockchain, Chugh recommends asking these three questions to conclude if a blockchain or database makes the most sense. The “yes” answers point you to a blockchain:
1. result multiple parties need to access and accomplish changes to the shared, single source of truth data? For instance, result multiple people need to update a shipment log or accomplish changes to a condense document? Yes? This speaks to the “distributed” understanding preeminent earlier, though it could point you to blockchain or a distributed database.
2. result you want a single, always-on trusted third party who can mediate information disputes? Yes? Now blockchain could subsist the best answer. Unlike a distributed database, in which a central administrator manages the data and has ultimate control of what data gets posted, blockchain data is held by many parties, and current information is verified through an agreed-upon consensus mechanism, rather than through a central administrator. There are many reasons you might not want to depend on a single, centralized party to manipulate data: concerns about delays, elevated fees, or that a single point of control is at risk of hacking or manipulation.
3. Are there parties on the blockchain who aren’t completely trusted? Perhaps there are people whose interests might not subsist aligned with each other’s—or who might not even subsist known to each other. Yes? Then again blockchain could subsist your answer. Blockchain doesn’t depend on trust, of either a central administrator to safeguard data or the people writing to the data source.
Once you’ve decided a blockchain is the right option, there’s a fourth question:
4. result you want to confine who can access the blockchain? Yes? Then you probably want a permissioned blockchain, whereby multiple organizations unite to contour a consortium with a founding organization that initially sets up the process of joining the blockchain platform. Unlike a centralized database, though, the leader doesn’t control the data source. In fact, each member can create its own blockchain instance, and the leader just establishes the process for joining them. Parties can add data—subject to verification via the consensus rules—but they can’t remove data, not even the founding organization.
Is the Problem Worth the Effort?
One final, more commercially driven question to regard before deciding whether to employ blockchain: Is the problem significant enough that a fix will result in a better bottom line?
“If it’s only going to expand your results 2%, let’s Go to the next department in your organization that might subsist in need of blockchain,” said Kelly LeValley Hunt, an advisor and investor in blockchain companies, on that selfsame panel at Blockland Cleveland. Sure, you’re probably doing a proof of concept for your first blockchain effort, but if the technology does what you hope, you want to apply it to a problem that your company really wants to address, where it’s worth investing in and scaling up an emerging technology.
Among those vital potential employ cases:
Pharmaceutical supply chains: There, blockchain could uphold multiple parties to better verify precisely which drug lots were transferred, at what time at each point of handoff, in an application to combat counterfeit drugs entering the market. The selfsame concept can subsist applied to a host of supply chain tracking, from assuring organic ingredients are going into food products to tracking combat minerals from mining through processing.
Franchise businesses: When franchisees and franchisors partake documents related to orders and invoices, having the transparency of a blockchain can better efficiency and trust.
Peer-to-peer mortgage lending: One challenge that keeps peer-to-peer lending from being used for mortgages is sharing each and every the personal financial information lenders would want to accomplish a mortgage decision. Blockchain could let a borrower partake that information with a peer-lending group.
Know your vendors: Your vendors could subsist required to bespeak that they’re in compliance with industry regulations and credentials, verified via blockchain by their issuers.
Tokenization: A number of loyalty programs are exploring blockchain to provide a common gauge of exchange—a token—that could let individuals pool airline miles, hotel points, grocery store rewards, and so on, in order to cash in benefits on other goods. Smart contracts on a blockchain could provide that gauge of exchange to discourse how many miles, for example, accomplish a token. Tokenization can subsist applied to a wide purview of employ cases, from securities to digital asset trading.
This purview of employ cases points to why, as leaders assume about where blockchain might uphold their businesses, they need to assume beyond projects with short-term returns, said Alex Tapscott, an author and founder of the Blockchain Research Institute, during his keynote at Blockland Cleveland.
“If you assume only about how you can redeem costs in your business today,” Tapscott said, “you’re going to miss out on how the technology might change your business in the future.”
Certification in Database Administration (DBA) can provide information technology professionals a competing career advantage.
Overview of Oracle DBA Certification

Oracle gives compliant training and online certification exams for its DBA technologies.
