*               soft    nofile  1024
*               hard    nofile  65536

4 Add the following line to the /etc/pam.d/login file, if it does not already exist:

session    required     pam_limits.so

5 Disable secure linux by editing the /etc/selinux/config file, making sure the SELINUX flag is set as follows:

SELINUX=disabled

6 Setup
Install the following packages:
yum install setarch-2* make-3* glibc-2* libaio-0* compat-libstdc++-33-3* compat-gcc-34-3* compat-gcc-34-c++-3* gcc-4* libXp-1* openmotif-2* compat-db-4* elfutils-libelf-* glibc-devel-* gcc-c+* libaio-devel-* libstdc++* sysstat-7* unixODBC-*

或者这样..
# From RedHat AS5 Disk 1
cd /media/cdrom/Server
rpm -Uvh setarch-2*
rpm -Uvh make-3*
rpm -Uvh glibc-2*
rpm -Uvh libaio-0*
cd /
eject

# From RedHat AS5 Disk 2
cd /media/cdrom/Server
rpm -Uvh compat-libstdc++-33-3*
rpm -Uvh compat-gcc-34-3*
rpm -Uvh compat-gcc-34-c++-3*
rpm -Uvh gcc-4*
rpm -Uvh libXp-1*
cd /
eject

# From RedHat AS5 Disk 3
cd /media/cdrom/Server
rpm -Uvh openmotif-2*
rpm -Uvh compat-db-4*
cd /
eject

7 Create the new groups and users:

useradd oracle
echo oracle | passwd --stdin oracle

8 Create the directories in which the Oracle software will be installed:

mkdir -p /u01/app/oracle/product/11.2.0/db_1
chown -R oracle.oracle /u01

9 Login as the oracle user and add the following lines at the end of the .bash_profile file:

# Oracle Settings
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1; export ORACLE_HOME
PATH=$ORACLE_HOME/bin:$PATH; export PATH

LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH

if [ $USER = "oracle" ]; then
  if [ $SHELL = "/bin/ksh" ]; then
    ulimit -p 16384
    ulimit -n 65536
  else
    ulimit -u 16384 -n 65536
  fi
fi

 

vim /etc/fstab
修改下面选项为
tmpfs /dev/shm tmpfs defaults,size=10240M 0 0
mount -o remount /dev/shm

查询使用率可以使用df -k /dev/shm
