ORA-00845: MEMORY_TARGET not supported onthis system

这个错误之前已经处理过,,因为tmpfs的大小MEMORY_TARGET的设置,就会报这种错误。

处理

[root@localhost ~]#umount tmpfs

(这里可能回报busy,重启一下再umount)

[root@localhost ~]# mount -t tmpfs shmfs -o size=1g /dev/shm (不用重启)


[root@localhost ~]# vi /etc/fstab(这里需要重启生效)

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


[root@localhost ~]# df -h
