1. Create oracle User Account
Login as root and create te user oracle which belongs to dba group. su -# groupadd dba# useradd -g dba oracle2. Setting System parametersEdit the /etc/sysctl.conf and add following lines: kernel.shmall = 2097152kernel.shmmax = 2147483648kernel.shmmni = 4096kernel.sem = 250 32000 100 128fs.file-max = 6553600net.ipv4.ip_local_port_range = 1024 65000net.core.rmem_default = 4194304net.core.rmem_max = 4194304net.core.wmem_default = 262144net.core.wmem_max = 262144
Note: You need reboot system or execute "sysctl -p" command to apply above settings.
For RedHat (OEL, Centos, WBL) 4 version: Edit the /etc/pam.d/login file and add following line: session required /lib/security/pam_limits.so
For RedHat (OEL, Centos) 5 version: Edit the /etc/pam.d/login file and add following line:
session required pam_limits.so
Edit the /etc/security/limits.conf file and add following lines: oracle soft nproc 2047oracle hard nproc 16384oracle soft nofile 1024oracle hard nofile 65536
3. Creating oracle directories# mkdir /opt/oracle# mkdir /opt/oracle/111# chown -R oracle:dba /opt/oracle
4. Setting Oracle Enviroment
Edit the /home/oracle/.bash_profile file and add following lines: ORACLE_BASE=/opt/oracleORACLE_HOME=$ORACLE_BASE/111ORACLE_SID=ORCLLD_LIBRARY_PATH=$ORACLE_HOME/libPATH=$PATH:$ORACLE_HOME/bin
export ORACLE_BASE ORACLE_HOME ORACLE_SID LD_LIBRARY_PATH PATH
Save the .bash_profile and execute following commands for load new enviroment: cd /home/oracle. .bash_profile
5. Download & Install1. Download and install required .rpm packagesSome additional packages are required for succesful instalation of Oracle software. To check wheter required packages are installed on your operating system use following command: rpm -q binutils elfutils elfutils-libelf gcc gcc-c++ glibc glibc-common glibc-devel compat-libstdc++-33 cpp make compat-db sysstat libaio libaio-devel unixODBC unixODBC-devel|sort
If some package is not installed then install it from installation media or download it from following locations:RedHat Enterprise Linux 4 - source packages onlyRedHat Enterprise Linux 5 - source packages onlyCentos Linux 4Centos Linux 5
This is example how to build RPM package from source package (libaio-0.3.105-2.src.rpm). Note gcc, make and rpm-build (and dependent) packages must be already installed on your system. # rpm -ivh libaio-0.3.105-2.src.rpm# cd /usr/src/redhat/SPECS/# rpmbuild --target i386 libaio.spec# cd ../RPMS/i386/# rpm -ivh libaio-0.3.105-2.i386.rpm libaio-devel-0.3.105-2.i386.rpm
Install the required packages using the rpm command: rpm -ivh <package_name>.rpm
2. Download the Oracle 11g release 1 (11.1.0.6.0) software from Oracle website.Extract the files using following command: unzip linux_11gR1_database.zip
3. Start the Oracle software installation process.
Now the system is prepared for Oracle software installation. To start the installation process execute the following commands: cd database./runInstaller
Note:If it don't open X-window,there may be something wrong on the xauth setting. list the root xauth setting and add the xauth setting to the oracle user.
[root@localhost oracle]# xauthUsing authority file /root/.Xauthorityxauth> listlocalhost.localdomain/unix:12 MIT-MAGIC-COOKIE-1 159b05bdace313ae273355f2d3e336aalocalhost.localdomain/unix:10 MIT-MAGIC-COOKIE-1 6f089e2055aefa800dbcdbacd0821d65localhost.localdomain/unix:11 MIT-MAGIC-COOKIE-1 e453959bfabbeff89eacfed6553b4042
add to oracle
[oracle@localhost ~]$ xauthUsing authority file /home/oracle/.Xauthorityxauth> add localhost.localdomain/unix:12 MIT-MAGIC-COOKIE-1 159b05bdace313ae273355f2d3e336aa
4. after intallation the database created,we will use sqlplus to access to the oracle.
It may trigger an problem like 'cannot restore segment prot after reloc'
we can use the cmd to resolve the issue. chcon -t texrel_shlib_t /usr/local/rsi/idl_6.1/bin/bin.linux.x86/*.so
