oracle 单实例DG(搭建篇一)

一,介绍

　　lodding...

二,安装前环境配置

　　　01,依赖包的安装:

yum install binutils-*
yum install compat-libstdc++-*
yum install elfutils-libelf-*
yum install elfutils-libelf-devel-*
yum install elfutils-libelf-devel-static-*
yum install gcc-*
yum install gcc-c++-*
yum install glibc-*
yum install glibc-common-*
yum install glibc-devel-*
yum install glibc-headers-*
yum install kernel-headers-*
yum install ksh-*
yum install libaio-*
yum install libaio-devel-*
yum install libgcc-*
yum install libgomp-*
yum install libstdc++-*
yum install libstdc++-devel-*
yum install make-*
yum install sysstat-*
yum install unixODBC-*
yum install unixODBC-devel-*

　　　　依赖包检查:

 rpm -q --qf '%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})\n' binutils \
 compat-libstdc++ \
 elfutils-libelf-devel \
 elfutils-libelf-devel-static \
 gcc \
 gcc-c++ \
 glibc \
 glibc-common \
 glibc-devel \
 glibc-headers \
 kernel-headers \
 ksh \
 libaio \
 libaio-devel \
 libgcc \
 libgomp \
 libstdc++ \
 libstdc++-devel \
 make \
 sysstat \
 unixODBC \
 unixODBC-devel \
 libXp

　　　　02,创建对应的用户,及管理用户

 /usr/sbin/groupadd oinstall
 /usr/sbin/groupadd dba
 /usr/sbin/useradd -g oinstall -G dba oracle

 echo oracle | passwd --stdin oracle

　　　　03, 修改内核参数　

 vim /etc/sysctl.conf

 fs.aio-max-nr =
 fs.file-max =
 kernel.shmall =
 kernel.shmmax =
 kernel.shmmni =
 kernel.sem =
 net.ipv4.ip_local_port_range =
 net.core.rmem_default =
 net.core.rmem_max =
 net.core.wmem_default =
 net.core.wmem_max = 

 sysctl -p

　　　　 04,修改系统限制

 vim /etc/security/limits.conf
 oracle           soft    nproc
 oracle           hard    nproc
 oracle           soft    nofile
 oracle           hard    nofile  

　　　　05,修改认证　

/etc/pam.d/login

 session    required     pam_limits.so

　　　　06,修改profile

 if [ $USER = "oracle" ]; then
         if [ $SHELL = "/bin/ksh" ]; then
               ulimit -p
               ulimit -n
         else
               ulimit -u  -n
         fi
 fi

　　　　07,创建需要的目录

 #创建必须目录:
 #ORACLE_BASE:存放各类日志
 mkdir -p /u01/app/oracle
 #ORACLE_HOME:存放程序的目录
 mkdir -p /u01/app/oracle/product/11.2./db_1

 #更改权限:
 chown -R oracle:oinstall /u01/
 chmod -R  /u01/
 chown -R oracle:oinstall /oradata

　　　 08, 更改环境变量

 su - oracle
 vim .bash_profile
 export ORACLE_BASE=/u01/app/oracle
 export ORACLE_HOME=/u01/app/oracle/product/11.2./db_1
 export ORACLE_SID=orcl
 export PATH=$ORACLE_HOME/bin:$PATH

 source .bash_profile

三,安装运行

　　　　./runInstaller

　　　　进入环境配置页面

报错提示:　　

 [oracle@oracle01 grid]$ ./runInstaller

 :q

解决:

 su 登入root 用户

 运行:

 xhost +

 再登入oracle 用户执行命令

原因:

 因为Xserver默认情况下不允许别的用户的图形程序的图形显示在当前屏幕上. 如果需要别的用户的图形显示在当前屏幕上, 则应以当前登陆的用户, 也就是切换身份前的用户执行如下命令
  xhost +

　　

安装界面:

　　　　

重新授权文件

[root@oracle01 ~]# chown -R oracle:oinstall /u01/
[root@oracle01 ~]# chmod -R 775 /u01/

看见有三个问题需要解决:

用root 运行命令

问题二:

　　yum install compat-libstdc++-33

其他问题就过滤把

等待安装完成

需要运行命令

好了到这里安装就完成了

主库搭建安装上诉方式

备库的话选择克隆的方式完成

备库需要跟改oracle 的位置有:

　

四,配置监听netca

　　　　进入oracle用户

　　 　　运行 netca

　　　　可能存在报错没有这个命令,可以查看.bash_profile是否配置环境变量合规,

　　　　并且运行　　source .bash_profile

　　

　　netca 启动各种问题:

　　　　

 .环境变量问题

 环境变量路径设置不对，找不到netca命令，--bash什么balabala提示，设置环境变量到ORACLE_HOME/bin

  

 .无法显示图形界面

 比较容易解决，用root用户执行xhost +命令，切到Oracle用户下再次执行

 如果依旧不行，查看是不是缺少libXp这个rpm包

 此错误的错误提示有java.awt等

 java.lang.NullPointerException

         at oracle.net.ca.NetCA.<init>(Unknown Source)

 .权限问题

 确定oracle用户和root用户分别什么用，重新把ORACLE_HOME赋权给oracle

 错误提示

 java.io.FileNotFoundException:/u01/cfgtoollogs/netca/netca_OraDb11g_home1_0809062PM5029.log(Permission denied)

 .主机名错误

 错误提示：

 Oracle Net Services Configuration:

 # An unexpected error has been detected by HotSpot Virtual Machine:
 #
 #  SIGSEGV (0xb) at pc=0x004f0ab3, pid=, tid=

 $JRE -mx64m $SRVM_PROPERTY_DEFS -Dsun.java2d.font.DisableAlgorithmicStyles=true -classpath

 由于默认主机名错误导致，修改配置文件/etc/hosts，修改

 # Do not remove the following line, or various programs
 # that require network functionality will fail.
 127.0.0.1               localhost.localdomain localhost 你的主机名

　 再root用户下xhost +

　 oracle用户

　　　export DISPLAY=:0.0

　　

最后点击 结束

五,安装数据库 dbca　　

七,从库网络配置netmgr　

　　　　命令行输入命令:　　netmgr

　　　　

八, 从库netca
