千家信息网最后更新 2024年11月29日ORACLE 10GR2 DATAGUARD ON RHEL 6

1、OS安装Red Hat Enterprise Linux Server release 6.4 (Santiago)
64位
IP：10.56.1.204 10.55.1.204

2、安装oracle 10Gr2所需rpm包
配置本地yum源，使用系统盘中的yum仓库即可
相关包安装
yum -y install binutils compat-libstdc++-33 compat-libstdc++-33.i686 elfutils-libel
f elfutils-libelf-devel gcc gcc-c++ glibc glibc.i686 glibc-common glibc-devel glibc-devel.i686 glibc-headers ksh libaio libaio.i686 libaio-devel libaio-devel.i686 libgcc libgcc.i686 libstdc++ libstdc++.i686 libstdc++-devel make sysstat
yum -y install libXp
yum -y install libXp.so.6
yum -y install libXt.i686 libXtst.i686

oracle安装参考文档
可参考文档：
http://www.cnblogs.com/mchina/archive/2013/03/08/2934473.html

3、创建用户及目录
~ ]# groupadd dba
~]# groupadd oinstall
~]# useradd oracle -g oinstall -G dba
~]# passwd oracle
~]# mkdir /u01/product/10.2.0/db_1 -p
~]# chown -R oracle.oinstall /u01
~]# mkdir /oradata
~]# chown -R oracle.oinstall /oradata/

4、设定相关内核参数及环境变量
~]# su - oracle
~]$ vim .bash_profile
unset USERNAME

umask 022
ORACLE_BASE=/u01; export ORACLE_BASE
ORACLE_HOME=/u01/product/10.2.0/db_1; export ORACLE_HOME
ORACLE_SID=wip; export ORACLE_SID
PATH=$ORACLE_HOME/bin:$PATH:$HOME/bin; export PATH

~]$ bash .bash_profile
~]$ echo $ORACLE_HOME
/u01/product/10.2.0/db_1
~]$ echo $ORACLE_BASE
/u01

root
vim /etc/sysctl.conf
# Controls the maximum shared segment size, in bytes
kernel.shmmax = 16000000000

# Controls the maximum number of shared memory segments, in pages
kernel.shmall = 4194304
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 = 1048576
net.core.rmem_max = 1048576
net.core.wmem_default = 262144
net.core.wmem_max = 262144

~]# sysctl -p
net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
kernel.sysrq = 0
kernel.core_uses_pid = 1
net.ipv4.tcp_syncookies = 1
kernel.shmmax = 16000000000
kernel.shmall = 4194304
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 = 1048576
net.core.rmem_max = 1048576
net.core.wmem_default = 262144
net.core.wmem_max = 262144

vim /etc/security/limits.conf
#use by oracle
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536

vim /etc/pam.d/login
#use by oracle
session required /lib/security/pam_limits.so

修改release文件
~]# vim /etc/redhat-release
Red Hat Enterprise Linux AS release 4 (Nahant Update 8)

5、oracle软件安装
解压文件
gunzip 10201_database_linux_x86_64.cpio.gz
cpio -idmv <10201_database_linux_x86_64.cpio
unzip p8202632_10205_Linux-x86-64.zip

xhost+进行图形化安装10g和10205patch

6、nsf挂载文件系统至主库，主库进行备份，备库还原
[root@DataGuard ~]# vi /etc/exports
[root@DataGuard ~]# cat /etc/exports
/mnt/rman 10.55.1.201(rw)
[root@DataGuard ~]# mkdir /mnt/rman -p
[root@DataGuard ~]# service nfs start
[root@DataGuard ~]# chown -R oracle.oinstall /mnt
[root@DataGuard ~]# chmod 777 /mnt
主库进行挂载
[root@LCM3RAC1 ~]# service portmap start
Starting portmap: [ OK ]
[root@LCM3RAC1 ~]# mount -t nfs 10.55.1.204:/mnt/rman /mnt/rman

主库进行备份至挂载文件内
rman target/
RMAN>backup database format '/mnt/rman/%d_FULL_%T_%u_%p_%c';

主库创建pfile，密码文件
[oracle@LCM3RAC1 rman]$ orapwd file=orapwwip password=oracle entries=5
[oracle@LCM3RAC1 rman]$ ls
orapwwip test WIP_FULL_20170109_0vrpjknq_1_1
[oracle@LCM3RAC1 rman]$ slqplus / as sysdba
-bash: slqplus: command not found
[oracle@LCM3RAC1 rman]$ sqlplus / as sysdba

Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bit Production
