oracle tmpfs 修改

原先是1.5G

[root@oracle2 oracle]# df  -h

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda3              73G   12G   58G  17% /
tmpfs                 3.0G  228K  3.0G   1% /dev/shm
/dev/sda1             788M   44M  705M   6% /boot
/dev/sr0              4.1G  4.1G     0 100% /media/CentOS_6.4_Final

[root@oracle2 oracle]#

2，编辑

vi  /etc/fsat  在 tmps后面加上 size=3G

3.编辑vi /etc/rc.d/rc.sysinit    

一、注释掉以下语句

#mount -f /dev/shm >/dev/null2>&1     

# Mount all other filesystems (except for NFS and /proc, which is already
# mounted). Contrary to standard usage,
# filesystems are NOT unmounted in single user mode.
# The 'no' applies to all listed filesystem types. See mount(8).
if [ "$READONLY" != "yes" ] ; then
        action $"Mounting local filesystems: " mount -a -t tmpfs,nonfs,nfs4,smbfs,ncpfs,cifs,gfs,gfs2 -O no_netdev
else
        action $"Mounting local filesystems: " mount -a -n -t tmpfs,nonfs,nfs4,smbfs,ncpfs,cifs,gfs,gfs2 -O no_netdev
fi

4  reboot
