Oracle’s Parallel Processing Architecture
Oracle’s parallel features fall into two broad categories: parallel execution and parallel server. Table 2.1 shows which parallel features are available under each combination of hardware and software architecture that Oracle supports. Oracle’s parallel processing features are available on all parallel hardware architectures. Table 2.1 provides examples of specific hardware architectures in each type. Oracle runs under many operating systems, including Windows NT, Alpha VMS, and variations of Unix.

Oracle Parallel Server (OPS) requires either a clustered system or an MPP system, because it uses a shared disk configuration. OPS is available for several Unix-based clusters and MPP systems. It also is available for Windows NT clusters. In addition, OPS runs on NUMA clusters such as IBM’s NUMA-Q. All major vendors, including Sun Microsystems, IBM, ...
