ORA-00845 解決
今天在虛擬機器上安裝oracle 11g,DBCA步驟到載入ASM磁碟的時候,突然報錯:
ORA-00845: MEMORY_TARGET not supported on this system
(這個問題是由於設定SGA的大小超過了作業系統/dev/shm的大小引起的)
matelink上的解釋是:This feature requires the /dev/shm file system to be mounted for at least %llu bytes.
/dev/shm is either not mounted or is mounted with available space less than this size.
Oracle在metalink的文件:Doc ID:Note:460506.1中進行了說明。解決這個問題只有兩個方法,一種是修改初始化引數,使得初始化引數中SGA的設定小於/dev/shm的大小,另一種方法就是調整/dev/shm的大小。
可以透過下面的方法修改/dev/shm:修改/etc/fstab檔案,增加或修改tmpfs 行:
[root@server ~]# df -k /dev/shm
Filesystem 1K-blocks Used Available Use% Mounted on
tmpfs 359816 0 359816 0% /dev/shm
可以看到是300多M,這裡給1G就行了。
[root@server ~]# vi /etc/fstab
/dev/VolGroup00/LogVol00 / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
devpts /dev/pts devpts gid=5,mode=620 0 0
#tmpfs /dev/shm tmpfs defaults 0 0
tmpfs /dev/shm tmpfs defaults,size=1024m 0 0
proc /proc proc defaults 0 0
sysfs /sys sysfs defaults 0 0
/dev/VolGroup00/LogVol01 swap swap defaults 0 0
"/etc/fstab" 8L, 622C written
[root@server ~]# umount /dev/shm
[root@server ~]# mount /dev/shm
[root@server ~]# df -k /dev/shm
Filesystem 1K-blocks Used Available Use% Mounted on
tmpfs 104857 0 104857 0% /dev/shm
