Folks,
I need some input related to some Linux settings for Oracle. The Linux distro is Red Hat 6.5. I have the following questions:

• I/O scheduler - The default scheduler is Completely Fair Queuing (CFQ). However, it seems that for the Oracle Unbreakable Linux kernel, the DEADLINE I/O scheduler is the default. For Red Hat, what do people normally set it to for highly IO intensive ERP systems?
• Mount point options - Are there any recommendations for the mount points related settings for the FC storage? (noatime, nodiratime, max_batch_time=0, nobarrier)
• Any other I/O related setting(s) that one should look into changing from the default value?

Any feedback will be appreciated.

Tanks,
Amir
