[Mekk <Marcin.Kasperski@xxxxxxxxxxx>]

I found this bug while looking for a way to resize /run/shm on Ubuntu
13.04. Still I can't find a way to resize it (on my laptop for some
reason it is 600MB - out of 6GB total memory - I need it bigger to
install Oracle or DB2).

Net is full of advice to mount --rebind this to change it's size, rather
ugly concept considering /run is usually not empty at the moment I can
remount it (and this option usually breaks some running apps)

So …… could anybody tell where is /run size configured?

Title:
  11.10 no longer has /etc/default/tmpfs file to set SHM_MAX

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I have 16 gb of memory and cannot figure out how to modify the new
  /run/shm mounted directory.  The default for this directory is 50% of
  available memory and I need to increase the size to support multiple
  databases in memory.  There used to be a /etc/default/tmpfs file that
  allowed to configure a different size.  Please let me know if there is
  a way to store the desired size for /run/shm.

  As a side note, there is a symbolic link created /dev/shm used for compatibility.  Unfortunately some applications require thsi to be mounted directory using bind option.  I have changed the /etc/init/mounted-dev.conf to use "mount --bind /run/shm /dev/shm" instead of the symbolic link and older programs are much happier.  This includes using Oracle database.
