下午想把一个11.2.0.2实例的memory_target AMM内存初始化参数修改到2000M，改好后重启发现实例起不来了，出现了ORA-00845错误:

在使用11G的AMM进行内存管理的时候，memory_target的值受到两个值的影响，一个是实际的服务器的物理内存，

故障：ORA-00845: MEMORY_TARGET not supported on this system
Oracle 11g的Linux版本在修改了MEMORY_TARGET或者SGA_TARGET后启动可能会报错：
SQL> shutdown immediate
Database closed.
Database dismounted.

tmpfs小于ORACLE SGA，默认的大小是RM（物理内存）的一半，由于tmpfs既使用内存,又可能使用了部分交换分区,所以不能指望使用tmpfs提高的读写速率倍数就等于(内存读写速率/磁盘读写速率)[root@oracle ~]# vim /etc/fstab我们要修改大小我们现在物理内存是1G 调整tmpfs大小，别超过内存+swap的大小。如果系统资源紧张，用完了内存，用到s

前段时间在虚拟机上装了个oracle11g，最近做测试，电脑资源有点紧张，把分配的4G内存改为2G内存了，在启动oracle的时候，会报如下错误[oracle@oracleserver ~]$ sqlplus / as sysdbaSQL*Plus: Release 11.2.0.1.0 Production on Sun Aug 10 00:08:44 2014Copyright (c) 198
