    Increasing Shared Memory

    Jimbo


      Hi,

       

      In Oracle Linux 6.3, I have changed my default /dev/shm using

       

      mount -t tmpfs shmfs -o size=3g /dev/shm

       

      And this worked. However I am trying to make the change permanent so I have changed my /etc/fstab entry to be

       

      tmpfs                   /dev/shm                tmpfs   size=3g         0 0

       

      However this has not worked. When I reboot my server /dev/shm returns to its original value

       

      Any ideas of how to make the change persist ?

       

      thanks,

      Jim
