What Is Correct Setting for _px_numa_support_enabled for 12c Databases That Wish to Use NUMA?
Last updated on JANUARY 18, 2017
Applies to:Oracle Database - Enterprise Edition - Version 126.96.36.199 and later
Information in this document applies to any platform.
We have two two-node RAC databases one at 188.8.131.52 and one at 184.108.40.206 that are intended to run using NUMA.
We have set the parameter "_enable_NUMA_support" to true on both databases, but when we list out the numa related parameters
we find that on 220.127.116.11 the setting for "_px_numa_support_enabled" is TRUE, whereas on 18.104.22.168 the value is FALSE. Our question
is: Will this difference affect parallel executions differently between the two version? We set the NUMA parameter following MOS note 864633.1
which details the process for 11gR2 we could not find an equivalent note for 12c.
