Mr. Scalzo on Oracle Linux disk Optimization

Mr. Bert Scalzo has published a superb benchmark titled “Optimizing Oracle 10g on Linux: Non-RAC ASM vs. LVM”.  Bert has a valid test-case using the “Benchmark Factory” tool to simulate real-world data loads and provides expert tips for optimizing Oracle 10g on Linux:

 

http://www.linuxjournal.com/article/8539

 

Bert shows the differences in performance between disks mapped with Oracle 10g Automatic Storage Manager (ASM) and the Linux Logical Volume Manager LVM using a TPC-C (online) and TPC-H (warehouse) benchmark.  Bert concludes:


For people doing RAC, ASM is a viable and credible approach for disk space management, with numerous administrative and maintenance benefits to its credit.

 

But for those simply doing non-RAC database deployments, ASM is not yet as scalable as the Linux ext3 filesystem using an LVM. . .

 

for people not doing RAC who care more about performance than administrative ease, for now you should stick with the Linux filesystems and an LVM.”
