Add user oracle
/usr/sbin/useradd -u 502 -g oinstall -G dba,oper oracle
Change password of user:
passwd oracle
Add kernel parameters to /etc/sysctl.conf
kernel.shmmni = 4096 kernel.shmmax = 4398046511104 kernel.shmall = 1073741824 kernel.sem = 250 32000 100 128 fs.aio-max-nr = 1048576 fs.file-max = 6815744 net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048586
Apply kernel parameters
/sbin/sysctl -p
Add following lines to set shell limits for user oracle in file /etc/security/limits.conf
oracle soft nproc 131072 oracle hard nproc 131072 oracle soft nofile 131072 oracle hard nofile 131072 oracle soft core unlimited oracle hard core unlimited oracle soft memlock 50000000 oracle hard memlock 50000000
Edit /etc/hosts file:
[root@1 ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.120.166 ora-c7.zhao.local
Verify your network setting:
ping -c 1 ora-c7.zhao.local
Modify .bash_profile for user oracle in his home directory add at the end file home/oralce.bash_profile.
# Oracle Settings #Oracle Settings export TMP=/tmp export TMPDIR=$TMP export ORACLE_HOSTNAME=O7-unixmen export ORACLE_UNQNAME=orcl export ORACLE_BASE=/u01/app/oracle export ORACLE_HOME=$ORACLE_BASE/product/12.1.0/db_1 export ORACLE_SID=orcl

Check which packages are installed and which are missing.as root copy this and excute this:
yum groupinstall "GNOME Desktop" -y yum groupinstall "Development Tools" -y yum install binutils -y yum install compat-libstdc++-33 -y yum install compat-libstdc++-33.i686 -y yum install gcc -y yum install gcc-c++ -y yum install glibc -y yum install glibc.i686 -y yum install glibc-devel -y yum install glibc-devel.i686 -y yum install ksh -y yum install libgcc -y yum install libgcc.i686 -y yum install libstdc++ -y yum install libstdc++.i686 -y yum install libstdc++-devel -y yum install libstdc++-devel.i686 -y yum install libaio -y yum install libaio.i686 -y yum install libaio-devel -y yum install libaio-devel.i686 -y yum install libXext -y yum install libXext.i686 -y yum install libXtst -y yum install libXtst.i686 -y yum install libX11 -y yum install libX11.i686 -y yum install libXau -y yum install libXau.i686 -y yum install libxcb -y yum install libxcb.i686 -y yum install libXi -y yum install libXi.i686 -y yum install make -y yum install sysstat -y yum install unixODBC -y yum install unixODBC-devel -y yum install zlib-devel -y
Create directory strucrure
mkdir -p /u01/app/oracle/product/12.1.0 chown -R oracle:oinstall /u01/ chmod 775 /u01/app
Disable selinux by editing the “/etc/selinux/config” file
SELINUX=permissive or SELINUX=disabled
Start Install database
Let’s start with database software installation as oracle user.
su - oracle
Unzip the database install files:
unzip linuxamd64_12c_database_1of2.zip unzip linuxamd64_12c_database_2of2.zip [oracle@ora-c7 ~]$ cd database/
Install
./runInstaller !!!This moment,there is a error: This is root... Introducing it in the back section. This does not show the graphical interface for the installation.

download: /2012年资料/8月/28日/Oracle 11gR2执行DBCA报错误
Confirm ORACLE_HOME:echo $ORACLE_HOME
Check perl version:perl -v
Verify the OUI Inventory:opatch lsinventory
//若没有将opath的路径加入到oralce用户的PATH变量中，也可以使用以下命令：$/u01/app/oracle/product/11.2.0/db_1/OPatch/opatch lsinventory
!opatch command is in '$ORACLE_HOME/OPatch/',环境变量PATH中没有包含该目录的话,直接敲入opatch命令是提示找不到改命令的,这时需要将该目录加入到PATH中.
cd 8670579
opatch apply //在8670579下执行
! opatch命令是在$ORACLE_HOME/OPatch/目录下,环境变量PATH中没有包含该目录的话,直接敲入opatch命令是提示找不到改命令的,这时需要将该目录加入到PATH中.
