fr and sr (from vmstat output) values are very high
Hi AIX Expert,
the fr (page freed/page replacement) and sr (pages scanned by page-replacement algorithm) values from the vmstat output (see below please) are very high. I usually see this high value during the oracle database backup. In addition, the page scan/page steal/ page faults values also very high..
Is this meaning that the server memory is maxed out?
Is there any tuning opportunity that we need to do?
Any advise is greatly appreciated. Thanks!

Hello,
I'm seeing this problem with vmstat, where the first line of output always has the same CPU statistics. For example:

Hi,
Recently from the vmstat output in the image attached, the first line of the cpu idle column shows a value of 15. Although the subsequent values show higher than 90, is there a reason why the first value is so low?
Is this a problem?
Thanks. (4 Replies)
