  1. Oracle启动报错

   ORA-00845: MEMORY_TARGET not supported on this system报错解决

   SQL> startup

   ORA-00845: MEMORY_TARGET not supported on this system

   查看原本大小

   [root@Shine2 oracle]# df -h|grep shm

    tmpfs                 505M  75K  505M  1% /dev/shm


   [oracle@Shine2 ~]$ vim /etc/fstab

   把文件中

    tmpfs                   /dev/shm                tmpfs   defaults        0 0

   改为

    tmpfs                   /dev/shm                tmpfs   defaults,size=1G        0 0


修改完成后，重新启动机器
