Oracle 11gr2 RAC安装笔记（二）配置系统参数

1、为 Grid Infrastructure创建组和用户

groupadd -g 1000 oinstall
groupadd -g 1200 asmadmin
groupadd -g 1201 asmdba
groupadd -g 1202 asmoper
useradd -m -u 1100 -g oinstall -G asmadmin,asmdba,asmoper -d /home/grid -s /bin/bash -c "Grid Infrastructure Owner" grid
passwd grid

2、为 grid 用户帐户创建登录脚本

su - grid
vim .bash_profile

添加内容如下：（其中 ORACLE_SID值根据节点不同来修改"+ASM1、+ASM2......"）

alias ls="ls -FA"
ORACLE_SID=+ASM1; export ORACLE_SID
JAVA_HOME=/usr/local/java; export JAVA_HOME
ORACLE_BASE=/u01/app/grid; export ORACLE_BASE
ORACLE_HOME=/u01/app/11.2.0/grid; export ORACLE_HOME
ORACLE_PATH=/u01/app/oracle/common/oracle/sql; export ORACLE_PATH
ORACLE_TERM=xterm; export ORACLE_TERM
NLS_DATE_FORMAT="DD-MON-YYYY HH24:MI:SS"; export NLS_DATE_FORMAT
TNS_ADMIN=$ORACLE_HOME/network/admin; export TNS_ADMIN
ORA_NLS11=$ORACLE_HOME/nls/data; export ORA_NLS11
PATH=.:${JAVA_HOME}/bin:${PATH}:$HOME/bin:$ORACLE_HOME/bin
PATH=${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin
PATH=${PATH}:/u01/app/common/oracle/bin
export PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:$ORACLE_HOME/oracm/lib
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/lib:/usr/lib:/usr/local/lib
export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/JRE
CLASSPATH=${CLASSPATH}:$ORACLE_HOME/jlib
CLASSPATH=${CLASSPATH}:$ORACLE_HOME/rdbms/jlib
CLASSPATH=${CLASSPATH}:$ORACLE_HOME/network/jlib
export CLASSPATH
THREADS_FLAG=native; export THREADS_FLAG
export TEMP=/tmp
export TMPDIR=/tmp
umask 022

3、为 Oracle 数据库软件创建组和用户

groupadd -g 1300 dba
groupadd -g 1301 oper
useradd -m -u 1101 -g oinstall -G dba,oper,asmdba -d /home/oracle -s /bin/bash -c "Oracle Software Owner" oracle
passwd oracle

4、为 oracle 用户帐户创建登录脚本

su - oracle
vim .bash_profile

添加内容如下：（其中 ORACLE_SID值根据节点不同来修改"racdb1、racdb2......"）

alias ls="ls -FA"
ORACLE_SID=racdb1; export ORACLE_SID
ORACLE_UNQNAME=racdb; export ORACLE_UNQNAME
JAVA_HOME=/usr/local/java; export JAVA_HOME
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1; export ORACLE_HOME
ORACLE_PATH=/u01/app/common/oracle/sql; export ORACLE_PATH
ORACLE_TERM=xterm; export ORACLE_TERM
NLS_DATE_FORMAT="DD-MON-YYYY HH24:MI:SS"; export NLS_DATE_FORMAT
TNS_ADMIN=$ORACLE_HOME/network/admin; export TNS_ADMIN
ORA_NLS11=$ORACLE_HOME/nls/data; export ORA_NLS11
PATH=.:${JAVA_HOME}/bin:${PATH}:$HOME/bin:$ORACLE_HOME/bin
PATH=${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin
PATH=${PATH}:/u01/app/common/oracle/bin
export PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:$ORACLE_HOME/oracm/lib
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/lib:/usr/lib:/usr/local/lib
export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/JRE
CLASSPATH=${CLASSPATH}:$ORACLE_HOME/jlib
CLASSPATH=${CLASSPATH}:$ORACLE_HOME/rdbms/jlib
CLASSPATH=${CLASSPATH}:$ORACLE_HOME/network/jlib
export CLASSPATH
THREADS_FLAG=native; export THREADS_FLAG
export TEMP=/tmp
export TMPDIR=/tmp 
umask 022

5、验证用户 nobody 存在

6、创建 Oracle 基目录路径

mkdir -p /u01/app/grid
mkdir -p /u01/app/11.2.0/grid
chown -R grid:oinstall /u01
mkdir -p /u01/app/oracle
chown oracle:oinstall /u01/app/oracle
chmod -R 775 /u01

7、为 Oracle 软件安装用户设置资源限制

vim /etc/security/limits.conf
------------------------------------------------------------------------------------------
grid soft nproc 2047
grid hard nproc 16384
grid soft nofile 1024
grid hard nofile 65536
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
-------------------------------------------------------------------------------------------

vim /etc/pam.d/login
----------------------------------------------------------------------------------
session required pam_limits.so
----------------------------------------------------------------------------------

vim /etc/profile
--------------------------------------------------------------------------
if [ \$USER = "oracle" ] || [ \$USER = "grid" ]; then
if [ \$SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
umask 022
fi
--------------------------------------------------------------------------

vim /etc/csh.login
--------------------------------------------------------------------------
if ( \$USER == "oracle" || \$USER == "grid" ) then
limit maxproc 16384
limit descriptors 65536
endif
--------------------------------------------------------------------------

8、配置内核参数

vim /etc/sysctl.conf

添加内容如下：

# Controls the maximum number of shared memory segments system wide
kernel.shmmni = 4096

# Sets the following semaphore values:
# SEMMSL_value SEMMNS_value SEMOPM_value SEMMNI_value
kernel.sem = 250 32000 100 128

# Sets the maximum number of file-handles that the Linux kernel will allocate
fs.file-max = 6815744

# Defines the local port range that is used by TCP and UDP
# traffic to choose the local port
net.ipv4.ip_local_port_range = 9000 65500

# Default setting in bytes of the socket "receive" buffer which
# may be set by using the SO_RCVBUF socket option
net.core.rmem_default = 262144

# Maximum setting in bytes of the socket "receive" buffer which
# may be set by using the SO_RCVBUF socket option
net.core.rmem_max = 4194304

# Default setting in bytes of the socket "send" buffer which
# may be set by using the SO_SNDBUF socket option
net.core.wmem_default = 262144

# Maximum setting in bytes of the socket "send" buffer which
# may be set by using the SO_SNDBUF socket option
net.core.wmem_max = 1048576

# Maximum number of allowable concurrent asynchronous I/O requests requests
fs.aio-max-nr = 1048576

执行命令生效：

sysctl -p
