1. Download The oracle11zip package [cloud disk centos details]

1)linux_11gR2_database_1of2.zip

2)linux_11gr2_database204 f2.zip

2. unzip and decompress the Oracle 11g file on the terminal

Decompress the package: Copy to/usr/local/

Unzip linux_11gR2_database_1of2.zip

Unziplinux_11gr2_database204 f2.zip

3. Check and install the installation package

Run the following command on the terminal: rpm-q gcc make binutils setarch compat-db compat-gcc-c ++ compat-libstdc ++-devel unixODBC-devel libaio-devel sysstat
The result is as follows:

Vel sysstat

Gcc-4.1.2-42.el5

Make-3.81-3.el5

Binutils-2.17.50.0.6-6.el5

Setarch-2.0-1.1

Package compat-db is not installed

Package compat-gcc is not installed

Package compat-gcc-c ++ is not installed

Package compat-libstdc ++ is not installed

Package compat-libstdc ++-devel is not installed

UnixODBC-2.2.11-7.1

Package unixODBC-devel is not installed

Package libaio-devel is not installed

Package sysstat is not installed

Analysis:

The package is not installed section above indicates that this package is not installed. You can find it on the CD and install it with rpm-ivh. These packages are used in the centos installation disk; you can also directly use the yum install package to install it. The specific operations are as follows:

Yum install compat-db

Successfully Installed: compat-db.i386. 2.52-5.1 Complete!

Yum install compat .)

Installed: compat * ...... Complete!

Yum install unixODBC-devel

Successfully Installed: unixODBC-devel.i386 0: 2. 2.11-7.1 Complete!

Yum install libaio-devel

Successfully Installed: libaio-devel.i386 0: 0. 3.106-3.2 Complete!

Yum install sysstat

Installed: sysstat. i386. 0.2-1. el5 Complete!

Note: You can run the rpm-q package again as follows:

Gcc-4.1.2-42.el5

Make-3.81-3.el5

Binutils-2.17.50.0.6-6.el5

Setarch-2.0-1.1

Compat-db-4.2.52-5.1

Package compat-gcc is not installed

Package compat-gcc-c ++ is not installed

Package compat-libstdc ++ is not installed

Package compat-libstdc ++-devel is not installed

UnixODBC-2.2.11-7.1

UnixODBC-devel-2.2.11-7.1

Libaio-devel-0.3.106-3.2

Sysstat-7.0.2-1.el5

As mentioned above: there are still four software packages not installed. Ignore this. In fact, the compat package we just installed already contains. You can continue to the next step.

4. System Parameters and user and directory settings
1) system parameter settings
Terminal: vi/etc/sysctl. conf

The following content is changed for this file:

# Kernel sysctl configuration file for Red Hat Linux
#
# For binary values, 0 is disabled, 1 is enabled. See sysctl (8) and
# Sysctl. conf (5) for more details.

# Controls IP packet forwarding
Net. ipv4.ip _ forward = 0

# Controls source route verification
Net. ipv4.conf. default. rp_filter = 1

# Do not accept source routing
Net. ipv4.conf. default. accept_source_route = 0

# Controls the System Request debugging functionality of the kernel
Kernel. sysrq = 0

# Controls whether core dumps will append the PID to the core filename
# Useful for debugging multi-threaded applications
Kernel. core_uses_pid = 1

# Controls the use of TCP syncookies
Net. ipv4.tcp _ syncookies = 1

# Controls the maximum size of a message, in bytes
# Kernel. msgmnb = 65536

# Controls the default maxmimum size of a mesage queue

# Below for oracle11g
Kernel. core_uses_pid = 1
Kernel. shmmax = 536870912
Kernel. shmmni = 4096
Kernel. shmall = 2097152
Kernel. sem = 250 32000 100 128

Net. core. wmem_max = 262144
Fs. file-max = 6553600
Net. ipv4.ip _ local_port_range = 1024 65000

2) add user groups and users

The terminal executes the following command:
# Groupadd dba
# Groupadd oinstall
# Useradd oracle-g oinstall-G dba
# Passwd oracle ----- password Repeat twice. Do not worry about the pop-up box such as root123.
3) create directory permissions

The terminal executes the following command:
# Mkdir-p/u01
# Chown-R oracle: dba/u01
# Chmod-R 755/u01

4) User Environment Variables

The terminal first switches the user to oracle:
Su-oracle

Terminal modify. bash_profile file:
Vi. bash_profile

The content of this file is as follows:
#. Bash_profile
# Get the aliases and functions
If [-f ~ /. Bashrc]; then
.~ /. Bashrc
Fi
# User specific environment and startup programs
PATH = $ PATH: HOME/bin
Export ORACLE_BASE =/u01/app/oracle
Export ORACLE_HOME = $ ORACLE_BASE/product/11.1.0.6
Export ORACLE_SID = orcl
Export PATH = $ PATH: $ ORACLE_HOME/bin: $ ORACLE_HOME/Apache/bin
Export TNS_ADMIN = $ ORACLE_HOME/network/admin
Export LD_LIBRARY_PATH = $ LD_LIBRARY_PATH: ORACLE_HOME/lib
Export NLS_LANG = AMERICAN_AMERICA.ZHS16GBK
Export ORA_NLS10 = $ ORACLE_HOME/nls/data
Unset USERNAME
Umask 022
