环境
OS: RedHat AS5.0
DB: Oracle10gR2 (running)
Oracle11gR1 (stop)
问题
启动11g数据库时报错:
[oracle@DN2WEB04 ccr]$ sqlplus "/as sysdba"
SQL*Plus: Release 11.1.0.6.0 - Production on Thu Aug 20 16:52:35 2009

Connected to an idle instance.
SQL> startup
ORA-00845: MEMORY_TARGET not supported on this system
原因
启用了11g的自动内存管理,且系统没有足够的可用共享内存(大于PGA+SGA)
[root@DN2WEB04 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
71G 56G 11G 85% /
/dev/sda1 99M 19M 76M 20% /boot
tmpfs 948M 569M 380M 60% /dev/shm
解决办法
增加共享内存:
[root@DN2WEB04 ~]# mount -t tmpfs tmpfs -o size=1600m /dev/shm
[root@DN2WEB04 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
71G 56G 11G 85% /
/dev/sda1 99M 19M 76M 20% /boot
tmpfs 1.6G 0 1.6G 0% /dev/shm
tmpfs 1.6G 0 1.6G 0% /dev/shm
