if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
4、修改linux内核,修改/etc/sysctl.conf文件
输入命令: vi /etc/sysctl.conf ,按i键进入编辑模式,,将下列内容加入该文

fs.file-max = 6815744
fs.aio-max-nr = 1048576
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
要使 /etc/sysctl.conf 更改立即生效,执行以下命令
[root@ ]#/sbin/sysctl -p
5、配置oracle用户的环境变量
首先,切换到新创建的oracle用户下,
输入:su – oracle ,然后直接在输入 : vi .bash_profile
按i编辑 .bash_profile,进入编辑模式,增加以下内容:
umask 022
export ORACLE_BASE=/home/oracle/app
export ORACLE_HOME=$ORACLE_BASE/oracle/product/11.2.0/dbhome_1
