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).

Bug No8451866
SummaryIncorrect multipath.conf setting affects RAC node failover. Settings(features = "1 queue_if_no_path") and/or (no_path_retry = queue) causes the node hang if io path fails. no_path_retry has to be set to the numeric value explicitly.
AffectsAll applications using device mapper multipath devices which have contingency plan in case of io path failure.
SymptomRAC node hangs if io path fails.
Solution/WorkaroundIn configuration file /etc/multipath.conf,set no_path_retry and polling_interval to the numeric values, for example, "no_path_retry=5" and "polling_interval=10" so as to disable queuing. These values depend on system workload.
