Ubuntu升级 12.04无法启动( ORA-00845: MEMORY_TARGET)

安装了oracle11g的ubuntu升级到12.04启动是报错误ORA-00845: MEMORY_TARGET not supported on this system。

原因12.04中将/dev/shm目录改成了/run/shm，虽然已经有符号链接但是仍然报错。

解决：

1、编辑oracle-shm

sundoct[email protected]:~$ sudo gedit /etc/init.d/oracle-shm

#! /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 --move /run/shm /dev/shm

mount -B /dev/shm /run/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

;;

esac

2、安装oracle-shm

[email protected]:~$sudo chmod 755 /etc/init.d/oracle-shm

[email protected]:~$sudo update-rc.d oracle-shm defaults 01 99

3、重启系统

[email protected]:~$sudo shutdown -r now

4、验证修改成功

s[email protected]:~$sudo　cat /etc/mtab |grep shm

none /dev/shm tmpfs rw,nosuid,nodev 0 0

/dev/shm /run/shm none rw,bind 0 0

５、启动数据库

[email protected]:~$su – oracle

[email protected]:~$dbstart

成功！！！
