Dear All,
My database is in RAC with 3 nodes.
In one node, ADDM report suggests that -
FINDING 1: 100% impact (657 seconds)
------------------------------------
Significant virtual memory paging was detected on the host operating system.
RECOMMENDATION 1: Host Configuration, 100% benefit (657 seconds)
ACTION: Host operating system was experiencing significant paging but no
particular root cause could be detected. Investigate processes that
do not belong to this instance running on the host that are consuming
significant amount of virtual memory. Also consider adding more
physical memory to the host.
Memory consumption is appearing as between 74 to 75, which is good enough.
Memory Usage %: 74.52 to 75.62
ADDM report consider memory used by oracle or non-oracle also?
Eager to know the answer.
Regards,
Ishika

Dear Michel,
Here, I am little bit confuse about the memory usage %.
Out of 3 nodes, 1 nodes is showing memory usage% is above 90%.
As we know that if it's value exceeds beyond 90%, need to increase physical memory.
Number of Instance - 3
Database ID/Instance: 725995297/2
Database Version: 10.2.0.5.0
help me out to understand the concept of memory usage % in RAC.
Regards,
Ishika
