System V shared memory will work without tmpfs in your kernel, however. Note that you do not need a tmpfs filesystem to be mounted for POSIX shared memory to work; you simply need the support in your kernel. POSIX shared memory isn't used too much right now, but this situation will likely change as time goes on. <BR /><BR /><BR />You can use it to provide shared memory tweaks to applications, like oracle.<BR /><BR />See:<BR /><BR /><A href="http://www-128.ibm.com/developerworks/library/l-fs3.html" target="_blank">http://www-128.ibm.com/developerworks/library/l-fs3.html</A><BR /><BR /><A href="http://dba-oracle.com/oracle_news/2005_4_19_getting_large_sga_linux.htm" target="_blank">http://dba-oracle.com/oracle_news/2005_4_19_getting_large_sga_linux.htm</A> Fri, 26 Aug 2005 07:47:05 GMT https://community.hpe.com/t5/operating-system-linux/some-dev-shm/m-p/3612761#M19309 Ivan Ferreira 2005-08-26T07:47:05Z
