MultiValue API available with Oracle9i AS
UniVerse, UniData, PICK and Prime INFORMATION applications run on Oracle 9iAS
Oracle9i Application Server when licensed through ONgroup or its distributors now includes a MultiValue API. Many large organizations, including VARs, government agencies, universities, healthcare and financial institutions, and Fortune 100 companies are redeploying mission-critical, MultiValue applications on Oracle. Few if any changes to the MultiValue applications are required to make the transition from PICK or U2 to Oracle.
Oracle Corporation in partnership with ONgroup is providing a MultiValue feature set with Oracle9iAS that supports applications developed on the common MultiValue platforms. BASIC Programs, Dictionaries, Paragraphs, PROCS, Sentences, Commands such as COPY, LIST, GET.LIST, CREATE.FILE, DELETE, SELECT, SORT--the common MultiValue features are implemented and work the same as they do in your MultiValue environment. UniObjects applications are compatible interface as well; so, graphical applications that use the UniObjects feature set of U2 will continue to work the same after the transition to Oracle.
With Oracle9iAS, the wall between the MultiValue environments and the relational world is gone. Now your existing MV applications can run on Oracle and use industry standard tools such as Crystal Reports and JAVA to create new applications and update the old.
Our last briefing summarized the benefits of Oracle9i AS Portals. Today's subject: Availability & Scalability
Many of you are responsible for the support of systems that require 24x7 operation. Down-time can often be measured in thousands, and even millions of dollars per minute.Depending on your industry sector, the numbers can be staggering:
Of those companies participating in a Cost of Downtime Survey: 46% said each hour of downtime would cost their companies up to $50k, 28% said each hour would cost between $51K and $250K, 18% said each hour would cost between $251K and $1 million, 8% said it would cost their companies more than $1million per hour.

Oracle9i Availability
A system failure will significantly impact your ability to provide quality customer service, which can in turn lead to the loss of a valuable customer. In order to avoid unplanned downtime, many companies implement redundant systems, which are known as hot standby systems. These systems are identical to production, but their purpose is to simply be there to provide continuity if the primary system fails.Standby systems obviously add a cost to your overall budget and do not provide any additional process power or capacity.
Oracle9i Real Application Clusters (RAC) introduce a breakthrough in clustered database technology, called Cached Fusion. With RAC, the system provides not only super-fast fail-over for high availability of data and applications, but utilizes the resources of all the servers to service planned and unplanned spikes in usage demand. Standby systems are no longer sitting idle, only waiting for a problem, their resources remain active and available. RAC is the software that organizes processors, memory, data and such in a way that a group of computers operates as if a single system.
The scalable architecture of the Oracle 9i database leaves no single point of failure and provides for death detection and automatic restart. Third party testing shows, that by taking advantage of the transparent application fail-over, a user does not even notice that a database went down as they are automatically failed-over to a surviving node. The user's query continues as expected without any user intervention and without any disruption to service. Click here for more information on Oracle's 9i Real application Cluster Scalability Demo.
Scale-out Pay as You Grow As the cost of computing power decreases, it becomes less expensive to purchase several smaller servers than one larger symmetrical multi-processing (SMP) machine. The ability to harness less expensive processing power is just the start of the cost savings you will realize with Oracle9i Real Application Clusters. With the ability to easily 'scale-out', Oracle9i Real Application Clusters means that you do not have to pay for processing power until you actually need it.
To Scale-out means that you can start out with smaller servers at an initial lower cost and simply add on additional servers as needed. The benefit in Oracle9i's RAC is that you can do this with no down time and no organizational disruption to your end users. By adding servers as needed you not only save in initial costs, but as state-of-the-art servers change so quickly, you avoid the nearly instant obsolescence, inherent in high-end systems. The ability to delay buying a server until you need it, a year or two down the line, allows you to take advantage of the best technology available over time. And if today's trends continue, you'll end up with more power for less cost.
Oracle9i Real Application Clusters provide highly available systems with the same hardware and software used to deliver scalability. Every server in a RAC database acts as a backup for every other server in the cluster. Real Application Clusters provide a 'hot standby' system, which means that the users of a failed server can be failed-over to an active server transparently. The benefit is a flexible architecture that gives you all the advantages of scalability and availability while still being easier to manage; and with the lowest total cost of ownership than of any other database on the market.
