We just got a request from our DB group to increase ramfs on RHE4 linux, running oracle 10g. One of our DBA's recommended installing hugemem kernel. We installed and followed the steps from this link to enable hugemem.
Our setup here, dl380 connected to EMC san localhost has 10gb of memory. I notice when trying to increase shmmax under proc limit is only 4gb. I want to push to 6gb and let DBA increase SGA upto 4gb. Does not work, can someone help? I also notice once we configured everything under this link we do not see file being created under /dev/shm which is mounted as ramfs.
Kernerl version. Linux <hostname> 2.6.9-42.0.3.ELhugemem #1 SMP Mon Sep 25 17:39:50 EDT 2006 i686 athlon i386 GNU/Linux
My technical skills are more Unix/Linux not Oracle. Need some help with this one...
