Memory usage
Dear All
we have HP-UX 11.31 on rx6600 server , the server has 8GB RAM , running oracle 10g DB ,from top command and our monitoring tool (HP openview) and from oracle grib reports it shows that the server had full memory utilization , but when we check from swapinfo command and from what oracle SGA receives we have 45% used from memory only , we see something from oracle related to change kernel parameter filecache , but I checked that this parameter preferred to be the default , any suggestion related to have the real memory used , and should we change this parameter or what ?

Re: Memory usage
Hello,
The default values are
filecache_min: approximately 5% of physical memory
filecache_max: approximately 50% of physical memory
If your system is used for ORACLE DB only , you can reduce these values since Oracle use their own caching [ System Global Area ] mechanisim .
may be you can set
filecache_min: 2%
filecache_max: 5%
regards,
Aneesh

Re: Memory usage
A part from memory other fact also need to check on the system
what is the value of vx_ninode
and time free lag
kctune | grep -i ninode
kctune | grep -i lag
for smooth running of hp-ux you need to tune your kernel and file system
