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 Unb= reakable Linux kernel, the DEADLINE I/O scheduler is the default. For Red H= at, what do people normally set it to for highly IO intensive ERP systems?

·         Mount point options – Are there any re= commendations for the mount points related settings for the FC storage? (no= atime, nodiratime, max_batch_time=3D0, nobarrier)

·         Any other I/O related setting(s) that one sh= ould look into changing from the default value?

 

Any feedback will be appreciated.

 

Tanks,

Amir
