I got message from Oracle that Memory usage is about 97%. When I checked with glance, I noticed that Sys Mem is quite high, becaue it is about 3,% Gb. Here is the output:<BR />Total VM : 7.2gb Sys Mem : 3.5gb User Mem: 4.6gb Phys Mem : 10.0gb<BR />Active VM: 4.6gb Buf Cache: 1mb Free Mem: 393mb FileCache: 1.4gb<BR /><BR />Why system is using so much system memory?<BR /><BR />Regards,<BR />Lovro<BR /> Tue, 20 Apr 2010 20:19:33 GMT Lovro VRES 2010-04-20T20:19:33Z https://community.hpe.com/t5/operating-system-hp-ux/high-system-memroy-usage/m-p/4621116#M377501 Hello,<BR /><BR />I have HP-UX 11.31 system with 10 Gb of RAM.
