oracle 11g数据库启动错误总结
1.启动数据库时提示ORA-00845: MEMORY_TARGET not supported on this system
(在oracle 11g中新增的内存自动管理的参数MEMORY_TARGET,它能自动调整SGA和PGA，这个特性需要用到/dev/shm共享文件系统，而且要求/dev/shm必须大于MEMORY_TARGET，如果/dev/shm比MEMORY_TARGET小就会报错)

解决方法:
[root@centos ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup-lv_root 25G 11G 14G 45% / tmpfs 1.0G 751M 274M 74% /dev/shm --是因为个值小了 /dev/sda1 485M 30M 430M 7% /boot /dev/sr0 3.6G 3.6G 0 100% /media/CentOS_6.4_Final [root@centos ~]# mount -o remount,size=2G /dev/shm --修改大小,就不会报错了 [root@centos ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup-lv_root 25G 11G 14G 45% / tmpfs 2.0G 751M 1.3G 37% /dev/shm /dev/sda1 485M 30M 430M 7% /boot /dev/sr0 3.6G 3.6G 0 100% /media/CentOS_6.4_Final [root@centos ~]#
