3. Set System Parameters
Modify # vi/etc/sysctl. conf to add the following code:

Kernel. shmall = 2097152
Kernel. shmmax = 2147483648
(Generally, you can set the maximum shared memory to half the physical memory. If the physical memory is 2 GB, you can set the maximum shared memory to 1073741824 (1G = 1024*1024*1024 ))

Run the # sysctl-p command after modification to make the kernel change take effect immediately.

4. Set Shell restrictions for oracle users:
A) edit the file: # vi/etc/security/limits. conf and add the following statement:

Ulimit-n 65536
Else
Ulimit-u 16384-n 65536
Fi
Fi

5. Configure the oracle user environment
Use an Oracle user to log on:
# Su-oracle
$ Vi. bash_profile

The content of the configuration file is as follows:

#. Bash_profile

# Get the aliases and functions
If [-f ~ /. Bashrc]; then
.~ /. Bashrc
Fi
# User specific environment and startup programs

Umask 022
TMP =/tmp; export TMP
TMPDIR = $ TMP; export TMPDIR
Export ORACLE_BASE =/opt/ora10
Export ORACLE_HOME =/opt/ora10/product/10.2.0.1
Export PATH = $ ORACLE_HOME/Apache/perl/bin: $ ORACLE_HOME/Apache/bin: $ PATH
Export ORACLE_OWNER = oracle
Export ORACLE_SID = oradb
Export ORACLE_TERM = xterm
Unset USERNAME

Iii. Installation Process
1. Restart the server to log on as an oracle user and start X-window for local installation.
# Su-oracle
$ Startx
(I started from Xwindow, So I skipped this step, but under root # xhost +)
Copy the Oracle10g CD file to the created installation folder (/tmp/oracle. (If the download is enabled, copy 10201_database_linux_x86_64.cpio.gz to/tmp/oracle,
1. Unzip the file: gunzip
2. Extract the file: cpio-idmv <
To the current directory)
2. Formal Installation
1) Click "Taskbar"> "application"> "System Tools"> "terminal ":
$/Tmp/oracle/runInstaller (CD to/tmp/oracle/$./runInstaller)

It is commendable that the 10g installation requires a Checking operating system certification step compared to 9i. It is particularly practical. The installation file automatically detects the required conditions. If any, the installer will report the cause to you.
2) after A short period of time, the "Select installation method" Information Window appears. Click "Advanced installation (A)". To continue the installation, click "next (N; go to the "specify product list directory and ID card" window: confirm the complete path of the product list directory (D):/oracle/oraInventory; specify the operating system group name (S): oinstall; click "next (N)" to continue installation. In the "Select installation type" window, click "Enterprise Edition (E)". To continue installation, click "next (N; go to the "specify home directory details" window. Name (M): OraDb10g_home1 path (A):/opt/oracle/product/10.2.0.1/. To continue the installation, click "next (N) "button;
3) go to the "product-specific prerequisite check" window. after a short period of inspection, the following check information window will appear. In the "Checking Network Configuration Requirements" project, select the content of the status bar and click "next (N)" to continue the installation. In the "select Configuration Options" window, click "Create Database (C )", click "next (N)" to continue the installation. In the "select database configuration" window, click "general purpose (G)". To continue the installation, click "next (N) "press the key to go to the" specify Database Configuration Options "window; settings in the database name; Global Database Name: oradb SID: oradb; database character set: Simplified Chinese ZHS16GBK; to continue the installation, click "next (N;
4) in the "select Database management options" window, click "manage Database using Database Control". To continue the installation, click "next (N; in the "specify database storage options" window, click "File System", specify the database file location:/oracle/product/10.2.0/oradata/, and click "next (N)" to continue the installation) "press the button. In the" specify backup and recovery options "window, click" do not enable automatic backup ". To continue installation, click" next (N; go to the "password of the specified database solution" window, click "all accounts use the same password", and enter the password. Click "next (N)" to continue the installation. In the "Overview" window, click "next (N)" to continue the installation. In the "installation" window, detailed installation is as follows: A. Installation part; B. copy file part; C. Connect to the data system part; D. Set the data system part;
5) enter the "Configuration Assistant" window: Configuration: Oracle Database Configuration Assistant, A new window "Database Configuration Assistant" will appear. Detailed Configuration process: A. Copying Database files; b. An Oracle instance is being created and started. C. A database is being created. After the preceding three parts are completed, a prompt window is displayed. Click OK.
6) configuration: iSQL * Plus is used to configure the auxiliary program. During the configuration process, a prompt window is displayed for executing the configuration script. Run the script on the terminal and run orainstRoot. sh script process: click "Taskbar"> "application"> "System Tools"> "terminal ",
$ Su root (converted to the root Super User Environment) Password: ****** (enter the root user Password)
#/Opt/oracle/oraInventory/orainstRoot. sh (enter the detailed path for executing the script)
Detailed operation:
#/Opt/oracle/product/10.2.0.1/root. sh (enter the detailed path for script execution)
Execution completed orainstRoot. sh, root. after the sh script is executed, close "superuser terminal" and return to the "execute configuration script" Prompt window. To continue the installation, click "OK" to go to the "installation ended" window, to exit the installer, click exit (X;

Iv. self-starting settings
Oracle 10 Gb needs to start the following services (for oracle Users)
$ Lsnrctl start
$ Dbstart
$ Emctl start dbconsole
$ Isqlplusctl start
Therefore, the following configuration is required:
By default, dbstart does not work. The following configurations are required:
1. Modify/etc/oratab
$ Vi/etc/oratab
Oradb:/opt/ora10/product/10.2.0.1: Y (changed from N to Y)
2. Copy a system-configured PFILE to the dbs directory.
# Cp/opt/ora10/admin/oradb/pfile/init. ora.2292007201045 $ ORACLE_HOME/dbs/init. ora (the $ ORACLE_HOME Path depends on the installation path)
Now you can test it.
$ Dbstart
Note: If the installation version is 10201, this error may occur:
Failed to auto-start Oracle Net Listene using/ade/vikrkuma_new/oracle/bin/tnslsnr
Modify the 78th rows of dbstart ($ ORACLE_HOME/bin/dbstart)
ORACLE_HOME_LISTNER =/ade/vikrkuma_new/oracle
ORACLE_HOME_LISTNER = $ ORACLE_HOME

$ Dbshut

Add the following code to/etc/rc. d/rc. local:
Su-oracle-c "lsnrctl start"
Su-oracle-c "dbstart"
Su-oracle-c "emctl start dbconsole"
Su-oracle-c "isqlplusctl start"

In this way, Oracle will automatically start after the server is restarted.
