Browse Published Validated Configurations  >  Validated Configuration Details
Program Scope

The goal of this program is to validate hardware with Oracle Linux and Oracle VM, and to identify issues and configuration details that would impact customer deployments. Oracle developed the program to go far beyond the standard certification testing normally performed with operating systems. Hardware vendors participating in this program perform thorough testing of the hardware in real-world configurations with Oracle Linux and Oracle VM.

This is not a database certification. Oracle Database is a component of the environment because it is demanding on hardware resources (processor, memory, cache, storage, network) and the operating system, and well suited for this advanced level of testing. The validation program uses Oracle Database as a tool and hardware is not certified with Oracle Database as a result of the validation program.

For more information please see the program's Frequently Asked Questions (FAQ).

Configuration Feedback
Bug No16823432
SummaryIO Performance degradation due to transparent hugepage enabled, when the system is under memory pressure.
Affects2.6.39-100 and upwards
SymptomWith THP enabled by default, RAC nodes may reboot due to slow I/O, when the system is under moderate memory pressure
Solution/WorkaroundDisable hugepages by the command echo never > /sys/kernel/mm/transparent_hugepage/enabled and echo never > /sys/kernel/mm/transparent_hugepage/defrag
 
Bug No17448938
SummaryThe parameter "readsector 0" in multipath.conf file causes megasas to reset and reboot the OS
AffectsOL6.4 with storage controller (PERC)H710P, H710P Adapter, H710P mini
SymptomIn multipath.conf file, under the defaults section, setting readsector 0 option causes the megasas to reset with messages in dmesg as "test kernel: megaraid_sas: Reset successful"
Solution/WorkaroundRemove the parameter readsector 0 in the defaults section in multipath.conf file
