Linux Installation Oracle

Under root user, perform the following steps:

1) Modify the user's shell limit, modify the/etc/security/limits.conf file

Input command: vi/etc/security/limits.conf, press I to enter edit mode, add the following content to the file.

oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536

Press ESC when editing is complete and enter ": Wq" to eject

2) Modify the/etc/pam.d/login file, enter the command: Vi/etc/pam.d/login, press the I key to enter the editing mode, the following content to join the file.

session required /lib/security/pam_limits.so session required pam_limits.so

Press ESC when editing is complete and enter ": Wq" to eject

3) Modify the Linux kernel, modify the/etc/sysctl.conf file, enter the command: vi/etc/sysctl.conf, press the I key to enter the editing mode, add the following content to the file

fs.file-max = 6815744 fs.aio-max-nr = 1048576 kernel.shmall = 2097152 kernel.shmmax = 2147483648 kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 4194304 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048576

Press ESC when editing is complete and enter ": Wq" to eject

4) to make the/etc/sysctl.conf change take effect immediately, execute the following command. Input: Sysctl-p display as follows:

linux:~ # sysctl -p net.ipv4.icmp_echo_ignore_broadcasts = 1 net.ipv4.conf.all.rp_filter = 1 fs.file-max = 6815744 fs.aio-max-nr = 1048576 kernel.shmall = 2097152 kernel.shmmax = 2147483648 kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 4194304 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048576

5) Edit/etc/profile, enter the command: Vi/etc/profile, press the I key to enter the editing mode, the following content to join the file.

if [ $USER = "oracle" ]; then if [ $SHELL = "/bin/ksh" ]; then ulimit -p 16384 ulimit -n 65536 else ulimit -u 16384 -n 65536 fi fi

Press ESC when editing is complete and enter ": Wq" to eject

6) Create the relevant users and groups as the owner of the software installation and Support group.

To create an Oracle user and password, enter the command:

useradd -g oinstall -g dba -m oracle passwd oracle

Then will let you enter the password, the password any input 2 times, but must be consistent, enter the confirmation.

7) Create database software directory and data file directory, directory location, according to their own situation, pay attention to disk space, here I put it under the Oracle user, for example:

Enter the command:

mkdir /home/oracle/app mkdir /home/oracle/app/oracle mkdir /home/oracle/app/oradata mkdir /home/oracle/app/oracle/product

8) Change Directory owner is owned by Oracle user, enter command:

chown -R oracle:oinstall  /home/oracle/app

9) Configure the environment variables for the Oracle user, first, switch to the newly created Oracle user,

Input: Su–oracle, and then directly in the input: Vi. bash_profile

Press I to edit. Bash_profile, enter edit mode to add the following:

export ORACLE_BASE=/usr/oracle/app export ORACLE_HOME=$ORACLE_BASE/oracle/product/11.2.0/dbhome_1 export ORACLE_SID=orcl export PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib

Press ESC when editing is complete and enter ": Wq" to eject

Second, the installation process

1) When the above system requires that the operation is complete, log off the system and log in with the Oracle user on the graphical interface. First copy the downloaded Oracle installation package to Linux and copy it with other SSH FTP tools.

Open a terminal and run the unzip command to extract the Oracle installation files, such as:

Enter the command:

unzip linux.x64_11gR2_database_1of2.zip unzip linux.x64_11gR2_database_2of2.zip

After the decompression is complete, the CD enters its extracted directory.

Enter the command:

CD Database

Use the LS command to view the files contained in the extracted database, such as:

2) Perform the installation, enter the command:./runinstaller

In this step, you can see that there are a lot of RPM packages available, we can find the missing packages from the Linux CD or ISO (or go to D:\linux_oracle11g_Package), use FTP to upload to Linux, and then use RPM–IVH xxx.rpm--nodeps–force to install (with the addition of--nodeps-Force on behalf of the mandatory installation, is in direct use RPM–IVH XXX.RPM installation is unsuccessful) wait until the package is all installed, again in the Oracle graphical interface, perform the installation process 2, down in the environmental inspection process, passed.

During the installation process 86% may encounter errors such as error (Error in invoking target ' mkldflags ntcontab.o nnfgt.o ' of makefile) executed in the following sequence of steps.

Upload the installation image Rhel-server-6.1-x86_64-dvd.iso,

Then hang the image file, such as/mnt

Note: The above is the installation of GCC, the software installation sequence can not be wrong.

The error was resolved according to this method.

After the installation is complete, you will be prompted to execute 2 shell scripts with root privileges. Follow the path to its prompt to find its location, such as: Mine is/home/oracle/app/oracle/product/11.2.0/dbhome_1/root.sh.

And/home/oracle/orainventory/orainstroot.sh a new terminal, enter the command:
