Install Oracle 11g in RedHat Linux 6.0

Steps for installing Oracle in Linux

Preparations before installation

Transmit oracle to the root directory through ssh (this installation is under VMware)

Installation Package for Linux for Oracle 11g

RedHat 6.0 Virtual Machine

1. Create users and groups

Groupadd oinstall

Groupadd dba

Useradd-goinstall-G dba-m oracle

Passwd oracle

(Oracle user login is used below)

2. Modify the environment variable of the orcle User: vi/home/oracle/. bash_profile

ExportORACLE_SID = ORCL

ExportORACLE_BASE =/app

Export ORACLE_HOME =/app/oracle

ExportPATH = $ ORACLE_HOME/bin: $ PATH

3. Create a folder (modify the folder and File Permission chmod 777 folder and file name)

Mkdir/app

Mkdir/app/oracle

Chown-Roracle. oinstall/app

4. Modify the Kernel Parameter file: vi/etc/sysctl. conf (root login)

Fs. file-max = 6815744

Fs. aio-max-nr = 1048576

Kernel. shmall = 2097152

Kernel. shmmax = 2147483648

Kernel. shmmni = 4096

Kernel. sem = 25032000 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. To make the/etc/sysctl. conf change take effect immediately, run the following command.

Input: sysctl-p display

6. Modify the vi/etc/host file (omitted)

A, ifconfig view ip

B. view the Host Name

7. Modify the version number of the Operating System

# Vi/etc/redhat-release

Change 6 to 4

8. install the software package

Rpm-ivh libXp-... rpm

Rpm-ivh libXp-devel-... rpm

9. log out of the oracle user and log on again.

10. decompress the oracle installation package with an oracle user

Unzip ....

11. Go to database./run ....

12. Create an installation directory

Mkdir-p/app/oracle

Chown-Roracle. oinstall/app

13. Set language Variables

Export

14. Log On As the root user and execute two scripts.

#./App/oraInventory/orainstRoot. sh

./App/oracle/root. sh

15. log on to the oracle server and configure the listener netca.

16. Start the database and configure dbca

17. enable the Service after restart (sqlplus system/Sa123456 as sysdba)

Startup

Copy the listener to app/admin/network.

You can create a table and use desc table to query the table.

18. Enter the graphic interface

# Cd/app/oracle/sqldeveloper/

./Sqldeveloper. sh

19. To enable oracle later, modify the oracle Kernel

Modify the Vi installation directory/. bash-profile

Oracle-home/sqldeveloper

If Step 1 is not performed, the listener (lsnrctl start) and Database Service (sqlplussystem/Sa123456 as sysdba) must be started each time the database is run)

# Cd/app/oracle/sqldeveloper/

./Sqldeveloper. sh

20. The following services will be started in sequence each time you start them.

ExportLANG = EN (set to English to prevent garbled characters)

Lsnrctl start (enable listener)

Sqlplus/nolog (go to database settings)

Conn sys as sysdba (Database startup mode, prompting you to enter the password)

Startup (enable all services)

Exit (Exit settings)

Sqldeveloper. sh (start database)
