内核参数

# vi /etc/

…………………………………………………………

…………………………………………………………

= 2097152

= 1024241824

= 4096

= 250 32000 100 128

-max = 6553600

_local_port_range = 1024 65000

_timestamps = 0

_sack = 1

_window_scaling = 1

_default = 4194304

_max = 4194304

_default = 262144

_max = 262144

完成后，运行以下命令激活更改:# /sbin/sysctl -p

为用户设置Shell 限制，编辑下面几个文件；

文件一# vi /etc/security/

#@student - maxlogins 4

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 1024

oracle hard nofile 65536

# End of file

文件二# vi /etc/pam.d/login

#%PAM-1.0

auth required pam_

................................................

................................................

session required /lib/security/pam_

加入红色标注的这一行；

文件三

# vi /etc/profile

………………………………………………………………………

export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUTRC

for i in /etc/profile.d/*.sh do

if [ -r "$i" ]; then

. $i

fi

done

unset i

unset pathmunge

if [ $USER = "oracle" ];

then

if [ $SHELL = "/bin/ksh" ]; then

ulimit -p 16384

ulimit -n 65536

else

ulimit -u 16384 -n 65536

fi

umask 022

文件四# vi /etc/

# /etc/

...........................................

if ( $USER == "oracle" ) then

limit maxproc 16384

limit descriptors 65536

fi

加入红色标注的几行； umask 022

endif

加入红色标注的几行；

设置环境变量要切换到

Oracle

用户下面进行，具体怎么设置根据自己的实际情况决定：

[root@it253 ~]# su - oracle

[oracle@it253 ~]$

[oracle@it253 ~]$ vi .bash_profile

# .bash_profile

# Get the aliases and functions

if [ -f ~/.bashrc ]; then

. ~/.bashrc

fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH

unset USERNAME

umask 022

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=/u01/app/oracle/product/11.1.0/db_1

export ORACLE_SID=orcl
