Explanation
BACKGROUND:
This ordinance authorizes the purchase of Real Application Clusters (RAC) technology (software licenses and support); related services through use of a State Term contract (STS-033, 533207-0 expiration date of June 30, 2007) with Mythics Corporation. The City's current hardware infrastructure consists of both UNIX and Windows servers, an optimal solution at the time of the city's technology consolidation. Since that time however, the hardware technology has improved, with one such improvement being the development of the RAC technology. RAC technology is made of up multiple smaller and interchangeable components. Through the uses of RAC technology, administrators can more easily isolate and address problem areas in database clusters and on-demand server coupling. Gartner Group has confirmed the benefits of RAC Technology for increasing service levels and reducing cost in the datacenters.
The recommendation to upgrade to a RAC infrastructure was made by Oracle Corporation representatives, who held extensive interviews with Department of Technology staff. Information gathered in these interviews suggested that if a server experiences downtime the failover process can take 2-4 hours. This will result in application inaccessiblity for critical applications such as 311, GIS, and Accela. RAC provides the ability to run and scale all application workloads on a cluster of database servers and provides the highest level of availability, scalability, and low-cost computing. If a node in the cluster fails, RAC continues running on the remaining nodes. If more processing power is needed, new nodes can be easily added to the cluster without system downtime.
In addition to reduced downtime (and the resultant overtime pay) the purchase of RAC technology carries other benefits such as, absence of a single point of failure, including a lower total cost of ownership; improved database administration productivity; economies of scale due to share...
