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
[oracle@Shine2 ~]$ sqlplus
