This script can be used to determine how many shared memory is used by “oracle” user’s processes, and how many huge page memory is used:
t=0; for i in `ipcs -m | grep oracle | awk ‘{print $5}’`; do echo “Oracle consumed other $i bytes”; let t=t+$i; done
echo
echo “Consumed by oracle as shared memory segments: $t bytes”
let t=t/1024
let g=t/1024/1024;
echo “Memory conversions: ~ $t kbytes | ~ $g GB”hugepagetot=`cat /proc/meminfo | grep HugePages_Total | awk -F’:’ ‘{print $2}’`
hugepagefree=`cat /proc/meminfo | grep HugePages_Free | awk -F’:’ ‘{print $2}’`
let usedhugepages=hugepagetot-hugepagefree
let totkbinhigepage=usedhugepages*2048echo “Total hugepage usage in kb: $totkbinhigepage”
