今天刚装了Oracle 11g,配制好了之后启动数据库时遇到下面的错误：
SQL> startup
ORA-27154: post/wait create failed
ORA-27300: OS system dependent operation:semget failed with status: 28
ORA-27301: OS failure message: No space left on device
ORA-27302: failure occurred at: sskgpcreates

看了一下文档，ORA-2715是么解释的：
ORA-27154: post/wait create failed
Cause: internal error, multiple post/wait creates attempted simultaneously
Action: check errno and contact Oracle Support
上网找了一些资料后，调整了下/etc/sysctl.conf，，修改kernel.sem为
kernel.sem =5010 641280 5010 128

使它生效
#sysctl -p
