ora-00845解决方法

[oracle@highgo1 ~]$ oerr ora 00845

00845, 00000, "MEMORY_TARGET not supported on this system"

// *Cause: The MEMORY_TARGET parameter was not supported on this operating system or /dev/shm was not sized correctly on Linux.

// *Action: Refer to documentation for a list of supported operating systems. Or, size /dev/shm to be at least the SGA_MAX_SIZE on each Oracle instance running on the system.

修改/etc/fstab

使用如下命令生效（根据情况修改大小）

 mount -o remount,size=3G /dev/shm
