FW:Why Using Red Hat Advanced Server

yahwist

Red Hat Linux Advanced Server has several features and enhancements that don't exist in other Red Hat versions. Among other things, Red Hat AS provides:
- Asynchronous I/O
- Process scheduler with CPU affinity, cache affinity, and per CPU runqueues and locks that provide better performance
- "mapped base" (base address for shared libaries) can be changed dynamically allowing larger sizes for the SGA
- Page frame of size 4 MB as opposed to 4 KB can be used for the SGA which improves performance for large SGAs
- The kernel can also use the "high memory" pool (physical memory above 1 GB) for allocating page table entries (PTE) which allow a higher number of Oracle connections
- Elimination of copy to bounce buffer improves I/O performance
