OVERVIEW


Choosing the Oracle Software 1111ii and RAC and RAC

– Customer decided Release 11Customer decided Release 11ii would would best meet their software needsbest meet their software needs

– Explained that Oracle9Explained that Oracle9ii Real Real Application Clusters (RAC) was an Application Clusters (RAC) was an architecture that allowed multiple architecture that allowed multiple instances to access a shared instances to access a shared database of datafilesdatabase of datafiles

– Customer was shown that Oracle9Customer was shown that Oracle9ii RAC would meet their 5 minutes RAC would meet their 5 minutes down time requirementdown time requirement


Choosing the Hardware What was chosen?What was chosen?

– SUN V880s. 2 clustered nodes for SUN V880s. 2 clustered nodes for backend, and 2 non-clustered nodes for backend, and 2 non-clustered nodes for middle tiermiddle tier

– A T3 storage array is in the same storage A T3 storage array is in the same storage enclosure as the SunFire V880. That enclosure as the SunFire V880. That means there are two T3 storage arrays means there are two T3 storage arrays connected via an optical hub. The arrays connected via an optical hub. The arrays provide both storage that is local to a provide both storage that is local to a given database server and storage that is given database server and storage that is shared between the two database servers shared between the two database servers
