ORA-00845: MEMORY_TARGET not supported on this system

ORA-00845: MEMORY_TARGET not supported on this system

如果遇到启动数据库时报错ORA-00845: MEMORY_TARGET not supported on this system
那应该是/dev/shm不够大引起,

1.修改/etc/fstab中的:
tmpfs                   /dev/shm                tmpfs   defaults        0 0
修改为:
tmpfs                   /dev/shm                tmpfs   defaults,size=3g        0 0
2.重启主机后再重启数据库即可
