本文介绍了一个用于配置Oracle 11g使用自动内存管理(AMM)的shell脚本。该脚本在系统启动时挂载/dev/shm，并设置大小为7GB，以确保Oracle 11g能够正常运行。

#! /bin/sh
# /etc/init.d/oracle-shm
#
#
case "$1" in
  start)
    echo "Starting script /etc/init.d/oracle-shm"
    # Run only once at system startup
    if [ -e /dev/shm/.oracle-shm ]; then
      echo "/dev/shm is already mounted, nothing to do"
    else
      rm -f /dev/shm
      mkdir /dev/shm
      #mount -B /run/shm /dev/shm
      mount -t tmpfs shmfs -o size=7000m /dev/shm
      touch /dev/shm/.oracle-shm
    fi
    ;;
  stop)
    echo "Stopping script /etc/init.d/oracle-shm"
    echo "Nothing to do"
    ;;
  *)
    echo "Usage: /etc/init.d/oracle-shm {start|stop}"
    exit 1
    ;;
