Well, I don´t have the answers, dunno about OS methods for pinpoint paging, but some points can be done here :

a) the symptom "glance shows 20Gb used under Sys Mem" out of 32 Gb IS very suspect : check the docs/links in http://unix.derkeiler.com/Mailing-Li...4-06/0010.html and http://forums11.itrc.hp.com/service/...threadId=68965

b) "I have a lot of oracle processes" : http://www.dba-oracle.com/t_tuning_cpu_usage_vmstat.htm speak about it, but the fact is that in outage situations (ie, low CPU power remaining, low memory available, etc) the system begins to steal pages for the processes - the assumption here is, you installed something new, this thing (maybe due to bugs) is consuming a lot of resources, this is the root cause... OR maybe not, simply your applications begun to do more work (bigger volumes, new programs doing more work, etc) and the timing is just coincidence , the new installs are not interfering...

My initial advice : check the links, see about configs, AND search for intensive processes (using top, iostat, glance in the OS, and the Oracle tools/dictionary views inside the db), tune them/stop them....


best regards,
