Operating Systems AIX AIX memory usage by processes Post 303025034 by rbatte1 on Tuesday 23rd of October 2018 08:48:45 AM

I regret that I am unable to hack into your servers and my crystal ball is in for servicing. Can you post some meaningful output illustrating why you think you have a problem?

It is usual for Unix/Linux servers of all flavours to keep their memory full, i.e. cached of anything they have used, just in case it can be re-used without having to wait for disk IO. Are you seeing paging space used? The output from lsps -a would show you this sort of thing. It is extreeeeemly unlikely that the two servers will have done exactly the same thing.

The output from vmstat 5 should also have a few columns about paging in & out counts.

If your server is not using paging space, then you don't generally have a memory problem. What is making you concerned?



Thanks, in advance,
Robin
