We have been experiecing log file sync waits for a long time, although this does not have a system wide impact, but after exhausting all the possible solutions to help improve the redo write performance, 3-party application provider has recommended to set below parameters.
I would appreciate your opinion regarding setting or not setting these parameters in production -
 
*.commit_logging='IMMEDIATE'
*.commit_wait='NOWAIT'

Standalone GI 11.2.0.3,
11.2.0.3 Single instance database on AIX 5.3

Howdy, Stranger!
