Redhat AS 5.0下配置Oracle 10g RAC [ 日期：2007-09-03 ] [ 來(lái)自：本站原創(chuàng ) ]
環(huán)境說(shuō)明:
操作系統: Redhat AS 5.0 (kernel 2.6.18-8.e15xen)
數據庫: Oracle 10g 10.2.0.1
配置步驟:
1.調整系統內核參數
vi /etc/sysctl.conf
=====================================
kernel.shmall = 2097152
kernel.shmmax = 4294967296
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 262144
net.core.wmem_default = 262144
net.core.rmem_max = 262144
net.core.wmem_max = 262144
=====================================
然后執行/sbin/sysctl -p 生效
2.設置oracle用戶(hù)的shell限制
vi /etc/security/limits.conf
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
3.修改登錄配置文件
vi /etc/pam.d/login
=====================================
session required /lib/security/pam_limits.so
vi /etc/profile
if [ \$USER = "oracle" ]; then
if [ \$SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
umask 022
fi
=====================================
4.配置Hangcheck計時(shí)器
vi /etc/modprobe.conf
=====================================
options hangcheck-timer hangcheck_tick=30 hangcheck_margin=180
=====================================
vi /etc/rc.local
=====================================
/sbin/modprobe hangcheck-timer
=====================================
5.創(chuàng )建用戶(hù)和安裝目錄(在集群主機上的用戶(hù)ID和組ID必須相同)
mkdir -p /u01/app/oracle/product/10.2.0/db_1
mkdir -p /u01/app/oracle/product/10.2.0/crs
groupadd -g 115 dba
groupadd -g 125 oinstall
useradd -m -u 175 -g oinstall -G dba oracle
passwd oracle
chown -R oracle:oinstall /u01
chmod -R 775 /u01
6.設置Oracle用戶(hù)的環(huán)境變量
su - oracle
vi .bash_profile
=====================================
# User specific environment and startup programs
umask 022
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1
export ORA_CRS_HOME=$ORACLE_BASE/product/10.2.0/crs
export ORACLE_PATH=$ORACLE_BASE/common/oracle/sql:.:$ORACLE_HOME/rdbms/admin
export ORACLE_SID=qzpoais
export NLS_LANG=AMERICAN_AMERICA.UTF8
export NLS_DATE_FORMAT="mm/dd/yyyy hh24:mi:ss"
export PATH=.:${PATH}:$HOME/bin:$ORACLE_HOME/bin:$ORA_CRS_HOME/bin
export PATH=${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin
export PATH=${PATH}:$ORACLE_BASE/common/oracle/bin
export ORACLE_TERM=xterm
export TNS_ADMIN=$ORACLE_HOME/network/admin
export ORA_NLS10=$ORACLE_HOME/nls/data
export TNS_ADMIN=$ORACLE_HOME/network/admin
export ORA_NLS10=$ORACLE_HOME/nls/data
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:$ORACLE_HOME/oracm/lib
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/lib:/usr/lib:/usr/local/lib
export CLASSPATH=$ORACLE_HOME/JRE
export CLASSPATH=${CLASSPATH}:$ORACLE_HOME/jlib
export CLASSPATH=${CLASSPATH}:$ORACLE_HOME/rdbms/jlib
export CLASSPATH=${CLASSPATH}:$ORACLE_HOME/network/jlib
export THREADS_FLAG=native
export TEMP=/tmp
export TMPDIR=/tmp
====================================
然后執行source .bash_profile 生效
7.編輯Hosts文件
vi /etc/hosts
====================================
10.133.129.181 OraclusterA
10.133.129.182 OraclusterB
10.133.129.183 OraclusterA-vip
10.133.129.184 OraclusterB-vip
10.10.10.1 OraclusterA-priv
10.10.10.2 OraclusterB-priv
====================================
備注:如果127.0.0.1記錄所對應的名稱(chēng)有出現主機名則要去掉,如OraclusterA.localhost.localdomain 改為localhost.localdomain,否則在安裝CRS的節點(diǎn)添加識別時(shí)會(huì )出錯
8.安裝所需軟件包
使用rpm -qa XXX 查看是否已安裝
以下為所需軟件包:
make 系統默認安裝
binutils 系統默認安裝
gcc 系統默認安裝
compat-db cd3中
compat-gcc cd2中
compat-gcc-c++ cd2中
compat-libstdc++ 系統默認安裝
compat-libstdc++-deve 系統默認安裝
openmotif21 cd2中
setarch-1.3-1 系統默認安裝
libxp
備注:RHEL5不同于RHEL4,默認沒(méi)有安裝libxp軟件包,直接導致openmotif無(wú)法安裝(依賴(lài)關(guān)系),并在安裝時(shí)提示:/jre/1.4.2/lib/i386/libawt.so: libXp.so.6: cannot open shared object file: No such file or directory ,必須到光盤(pán)中找到對應的軟件包并安裝,詳見(jiàn):metalink Note:443617.1
