hi guys i hope you can help me with this situation.
i have 2 lpar with aix 7.1 and oracle 11gr2 in grid mode.
when i start nmon to check the current system health i notice that page fault are over 3000/s. than i have opened a case with ibm and they say that the problem is not paging nor pinning nor memory but heavy i/o on disks from an application.
infact i have 30% of free memory and 0.3% of page space used and 16,7& of pinned memory.
now i thinks oracle arc is the cause, but how can determine exactly which application is creating those page faults?
i have tried with noon with t option and then 5(for i/o) but it seems all normally.
any suggest would be appreciated.
Thanks
